THE TECHNICAL AND CUSTOMER MAGAZINE Ready for the future! Versatile safety technology according to new European standards. Can you see the light? Our smart camera family is growing and thus ideally prepared for the future. Edition No. 06 04/10 Page 02 Editorial “Good preparation keeps you safe.” A clever man once said: “He who thinks of tomorrow today cannot easily be surprised the day after tomorrow either”. It is this anticipatory view that has characterized Leuze electronic’s specialists from the very beginning. It ensures that our customers are ideally prepared for the future. This is reflected in the most recent developments regarding safety at work. Not only were the new standards EN ISO 13849 and IEC 61508 introduced, but the validity of the old standard EN 954-1 was also extended by two years. Nevertheless: postponed is not abandoned. Machine manufacturers rightly deal with this subject quite intensively. This leaves two years to make clever use of these changes. We have developed our new products according to the future standards and have adapted and recertified proven existing products where necessary. We don’t just support you through competent advice, but can also offer sustainable solutions with our products. Our seminars, workshops and training (“Machine Safety Services”) complement this offer. It becomes apparent in the validation of safety chains that a great deal of attention is paid to the mathematics. Other important aspects surrounding the sensor should not miss out, however. For example, numerous new features offer the opportunity to reduce cost during the life cycle of a machine and to increase efficiency. Our most recent example in this context is the new Multiple Light Beam Safety Device MLD—the first three-beam transceiver for access guarding - high-quality safety technology at minimum cost. The concept of configuration via fixed wiring has been advanced consistently in this case and permits installation without special configuration tools. Read about other examples in this issue that generate a high customer value. Further issues will follow.

Interview with Mr. Matthias Höhl, director of our subsidiary in China Page 04 Fast reading of moving codes Smart camera LSIS 422i reads dot-peened, laser-etched and printed codes With the device version LSIS 422i, which can also read and verify moving codes, Leuze electronic offers users the option of code reading via smart camera. Motor-driven focus adjustment, uniform illumination of free-form surfaces, and connection technology suitable for industry characterize the smart cameras of the LSIS 400i series. Equipped with eight freely configurable I/O ports, one RS232 interface and one Ethernet interface, the code readers can conveniently be configured via a web browser. A display for diagnostics and status display, as well as standalone operation, round out the advantages of the series. The new LSIS 422i also offers all these features. It can read up to 99 barcodes per image, whether printed, laser-etched, or dotpeened, and 2D Data Matrix codes. The fact that “only” one image is captured also allows codes to be read on quickly moving parts. A prerequisite for this is a short exposure time that can be set to a minimum of 54 µs for the LSIS 400i. Determining and evaluating code quality In addition to reading the codes, quality parameters of the read codes can optionally be determined and evaluated. This means the code quality can be checked immediately after printing to ensure readability. The user can specify the quality criteria himself and, if necessary, Adjustable parameters optimize performance One of the options for optimization via software is the specification of pre-filters with certain code features in order to speed up the reading process. For 1D codes, you can also increase the step size of the search. Other options are read direction and inverted codes. Inverted twodimensional codes can also be read. With these, the reading mode can furthermore be set: “fast” for codes of good quality or “robust” for more critical, e.g. directly marked, codes. If Data Matrix codes are not presented as a square shape but as a kind of hole pattern, the algorithm recognizes these codes as well. Even reflected codes can be read by the software. define a value below which a warning is output. In reference code comparison, the reader also outputs a message if the code read does not conform to the specification. Together with the configurable data output, the new code reader can be used just as flexibly as the other Leuze barcode readers. Page 05 Simply innovative — MLD 500, MLD 300 Multiple Light Beam Safety Devices with integrated muting Leuze electronic presents Multiple Light Beam Safety Devices and, for the first time, 3-beam transceiver systems as well in various function classes for access guarding, also with muting. And no additional modules are necessary! It is advantageous from a cost effectiveness and optimum usability standpoint to use safety sensors that are characterized by functions that match the specific requirements of the given application as closely as possible. Leuze electronic developed the new MLD 300 (type 2, PLd) and MLD 500 (type 4, PLe) series Multiple Light Beam Safety Devices especially with this in mind. The individual models of the respective series are equipped with certain features and capabilities (function classes). By selecting a given function class, the user can appropriately determine the performance of his safety sensor for the application and the respective requirements. For example, the start/restart interlock and contactor monitoring functions are available and, if necessary, various muting modes can be selected. As a result,the series can be used both as standard access guarding as well as for applications where sequential, parallel or partial muting is required. Additional muting devices are not required, thus simplifying construction and lowering costs during setup of the muting application. Higher MLD function classes, such as MLD 330 or MLD 530, feature an integrated muting indicator and a 7-segment display, which the user can use to immediately determine the cause of sensor behavior and initiate the proper countermeasures. The series is predestined for wide-area perimeter guarding, which is realized with Deflecting Mirrors. Ranges of up to 70 m and operating temperatures up to –30 °C are here possible. With the integrated laser alignment aid, alignment of such safeguards is noticeably simplified. A reflective element integrated in the cap on the receiver side of the system ensures clear visibility of the alignment laser spot, even over long distances. The Deflecting Mirror columns necessary for perimeter guarding can be simply and quickly aligned, step-by-step. The setup time is considerably reduced. In addition, with the new BT-240 swivel mount, the safety sensor can be flexibly turned 240° on its own axis, easily aligned and reliably mounted—an extremely practical solution for further simplifying and accelerating use of the devices. We l l wo r t h s e e i n g! MLD video clip at www.leuze.com/mld-clip Page 06 inside — BCL 548 548i World’s first barcode reader with integrated PROFINET interface Thanks to the integrated interface, the barcode reader BCL 548i can be operated directly in a PROFINET network. Furthermore, thanks to integrated switch technology, the BCL 548i can also be used in a line network structure. This minimizes cabling requirements and offers a high level of transparency and flexibility. Simple start-up and operation The integrated PROFINET interface permits the BCL 548i to be connected directly to a control. The usual detour via an additional gateway becomes unnecessary. Moreover, with the integrated PROFINET interface, the user can easily operate the device via the control. The device is configured by selecting modules in the control and then transferring them from the control directly to the BCL 548i. Should it be necessary to swap out a device, the configuration is automatically taken over by the new device. By means of the integrated switch function, additional devices can be connected to one another in the PROFINET in a line structure, as is typical for fieldbuses. d Worl t firFsINET PRO ide ins Fail-safe connection and short mounting times High system availability through code reconstruction technology The BCL 548i connects via standardized M12 plugs and ready-made cables, making wiring economical, transparent and fail-safe. The well-designed fastening concept contributes to easy handling and, in particular, reduces mounting time. The proven dovetail technology and four M4×6 threaded holes make possible simple and convenient fastening in the system. Alignment and configuration are simplified by a well-structured and transparent presentation of the values in a multi-language display. The menu navigation is user friendly and is performed using four buttons. Two additional LEDs provide a quick overview of the device status. During operation, the superior performance of the BCL 548i ensures high reading reliability. The innovative code reconstruction technology (CRT) guarantees this even in fast processes. The advantages are particularly apparent with turned labels, with short label heights or with codes that must be read at extreme inclines relative to the center axis. Even partly damaged or soiled codes can be decoded. In addition to equipment and technology, the new, future-oriented barcode readers of the BCL 548i series convince with a level of performance that flexibly satisfies every application-specific requirement, thereby saving time and ensuring high system availability, even under difficult conditions and increasingly faster processes. Flexibility through a wide range of models The wide range of barcode readers offers the user a high level of flexibility for a variety of applications. The user can select from four different optics models for various module widths ranging from 0.25 to 1.0 mm. With identical reading fields, all are available as line scanners, oscillating mirror models or deflecting mirror models of the latest generation. The high-performance optics, with a symmetrical, optical opening angle of ±30°, permit wide opening of the reading field with large depth of field, even at close range. Page 07 In the third dimension 3D sensor system—high-tech reduced to the basics . Ulrich Balbach, Head of the Optoelectronic Sensors Division at Leuze electronic . contact What is a 3D sensor system? What does it mean? . For optical sensors, we have so far talked about measuring or switching systems that determine the distance or the presence of an object by emitting a light beam. These so-called one-beam systems usually contain all distance information that is energetically or geometrically usable. In addition, there are and have been surface-illuminated camera-based systems that evaluate surface elements (called pixels) two-dimensionally in the plane with regard to their light/dark distribution, usually at a higher resolution. If one combines the distance information of the one-beam systems and the high energy deposit of their illumination with the surface evaluation of a camera chip, one can obtain additional depth information—known as the third dimension. Along a laser line, one obtains not only the location of each pixel in an x/y-coordinate system and its brightness value, but also the distance via the z-coordinate. Balbach contact Now what are the benefits of 3D sensor systems? . The advantages are obvious. The additional distance information means that you depend far less on brightness or color differences on the object. A body’s edge, for example, can safely be distinguished from a light/dark transition in the scene in this way. This provides detection reliability. In addition, the energy deposit is higher by a factor of 1,000 for the applied, structured illumination when eye safety is taken into account. Balbach . contact This sounds pretty complicated. Doesn’t this result in quite a lot of downstream effort? . No, just the opposite. The processing of a 3D signal can be considerably simpler. Body edges, highest points and lowest points, just to mention a few examples, are contained directly in the signal and can be extracted via simple pair comparisons. Extensive intermediate storage of the image data for feature extraction is no longer required. If the user wishes to accept all data unfiltered in their entirety from the sensor, he can use a high-performance 100 MBit/s (MBaud) Ethernet interface. Balbach . contact What are the areas of application for such a 3D sensor? . For many applications, simple point-shaped information is more than insufficient nowadays. For example, determining a pick position for the robot’s grabber requires a 3D coordinate in space. Or, if one wants to determine the volume of an object, this does of course require the height in addition to the length and width. Balbach . contact All of this sounds like a lot of high-tech. Aren’t these 3D sensors very expensive? . Our developers at Leuze electronic have landed a big coup. They have taken this highly challenging technology and, with a few smart tricks, have reduced it to the basics, so that the new light section sensor family LPS can offer the right product model at the right price and performance for the situation. The products range from “simple” Line Range Sensors (LRS) suitable for object detection to models for measuring the position and width, i.e., the Line Edge Sensors (LES). For high-end applications in 3D measurement, various versions of Line Profile Sensors (LPS and LPS plus) are available.

The company has put a new high-bay warehouse into operation which, due to the conditions present, is made of a somewhat unusual building material: wood. As the general contractor, the Voralberg (Austria) branch of LTW Intralogistics GmbH supervised the project and used sensors from Leuze electronic for this extraordinary project. With the expansion of production capacity to more than one million tons, it was necessary for Salinen Austria AG to construct a new high-bay warehouse at the production facility in Ebensee (Austria). “In addition, the construction of an automatic, single-level distribution system reduces transport costs by up to 40%,” explains the responsible logistics director of Salinen Austria AG. The entire logistics infrastructure was realized by LTW Intralogistics: “As the general contractor, LTW supplied multiple complete systems, consisting of high-bay storage devices, conveyor systems, control technology and software,” reports Ralf Becker from the marketing department of LTW Intralogistics in Wolfurt, home to the Austrian headquarters of the company. Leuze electronic sensors are essential Sensor technology from Leuze electronic, such as the BPS 34 barcode positioning systems, DDLS 200 data transmission photoelectric sensors, HRT 96 light scanners or ROBUST Multiple Light Beam Safety Devices used in Ebensee, have, for years, played an important role in the performance of LTW projects. “They provide us with the necessary process availability for fully automatic operation,” confirms LTW, where, in the context of the system constructed for Salinen Austria AG, the largely corrosion-resistant device versions are particularly valued. These are also the reasons for the wooden construction of the warehouse at Salinen Austria: the special challenge is the salt, which would necessitate extensive corrosion-protection measures on the steel typically used to construct high-bay warehouses. Wood was, therefore, the better choice here. Even without any special treatment, wood is largely resistant to direct contact with salt and to the high level of salt present in the air in the warehouse (Figure 1). Even metal screw connections were eliminated, opting instead for traditional carpentry dovetail joints. Everything that could be made of wood, was. This includes ladders, provided for accessing the high-bay storage devices for maintenance work, or the stands for the control panels. Many other system parts, such as the high-bay storage devices, were hot-dip galvanized and then coated in three layers. A total of six high-bay storage devices with a height of approximately 23 m, with travel speeds of up to 4 m/s and lifting speeds of up to 1.5 m/s, ensure a rapid flow of goods. Each of the high-bay storage devices moves up to 92 pallets per hour. Figure 1: Wood is an unusual building material for a high-bay warehouse. For the Salinen Austria AG salt warehouse, however, it is ideal. Figure 2: Absolute distances are encoded on the plastic tape of the BPS 34. Shown here is the tape affixed to the vertical axis of a high-bay storage device. Page 11 Precise positioning with barcodes The positioning of the high-bay storage devices in the high-bay warehouse and of the side-tracking skates in the pre-zone occurs with BPS 34 barcode positioning systems, each of which consists of two easy-to-handle components: a read head and the barcode tape. With a high level of functional reliability and minimal maintenance, the BPS from Leuze electronic are predestined for use in such demanding applications. The plastic code tape, on which the absolute distances are encoded, is a key contributing factor here (Figure 2). The code is nearly indestructible and insensitive to UV light and many industrial environmental influences, such as various oils and chemicals, humidity, etc. For simple mounting, the tape, produced by Leuze’s Austrian partner, Schmachtl GmbH of Linz, is self-adhesive and affixed to V4A stainless steel. It can easily be attached to the floor with plastic holders. With the reader system, a laser scans the position information with a reproducibility of ±1 millimeter. The positioning system transmits the respective, calculated position value to the control every 2 milliseconds. One unique feature here is that the read head always reads multiple codes on the code tape simultaneously (Figure 3). Thus, individual soiled or damaged codes do not affect the measurement system, which operates using absolute values, thereby ensuring reliable position detection. Optical data transmission without interference All data is exchanged between the high-bay storage devices, the side-tracking skates and the control via data transmission photoelectric sensors DDLS 200. They permit contact- and wear-free optical communication without interference at a transmission rate of up to 2 Mbit/s over distances of up to 500 meters (Figure 4). The device versions used here are designed for aisle lengths of up to 120 meters. Each consists of a pair of two transmitter and receiver units, which transmit and receive the data on different frequencies via a pulsed, invisible, infrared laser beam. Here, the laser beam of the transmitter is precisely tuned to the frequency of the opposing receiver. This enables bidirectional communication and prevents mutual interference or reflections. In addition to the device performance, LTW Intralogistics is particularly pleased with the simple commissioning. The patented SHA (Single Hand Adjustment) process for one-man adjustment allows a single person to precisely align the data light beam. Salinen Austria AG also uses other products from Leuze electronic in the area of space occupancy detection within the scope of double-deep storage in the highbay warehouse. For example, reflection light scanners with background suppression of the 96 series are used. The laser light scanners have a large detection range. They operate according to the principle of light propagation time measurement and facilitate use under extreme conditions with respect to light and gloss. Furthermore, they offer good black/white behavior over the entire adjustment range and a switching behavior that is independent of the direction of movement. Figure 3: The read head of the BPS 34 always reads multiple codes on the code tape simultaneously (source: LTW Intralogistics GmbH) Figure 4: DDLS 200 data transmission photoelectric sensors on high-bay storage devices facilitate contactand wear-free optical communication. Page 12 Safe in a few steps Premounted Safety Sensor Sets simplify the setup of access guarding it is often necessary for the material that is being processed to be able to pass through the protective device without restricting productivity. For this purpose, robust protective devices that include the so-called muting function and that can be easily integrated in the safety system of the system are required. - Freedom from interference— the system does not need to be adapted to the safety technology This was easily solved with CPSET from Leuze electronic, based in the Swabian town of Owen/Teck (Figure 2). CPSET are customized complete systems consisting of optical protective devices for access safeguarding and feature an integrated muting function. CPS E T-M24 Components increase complexity Figure 1: Systems for transport and handling in the wood industry. Machine manufacturers wishing to implement access guarding with muting are often confronted with the problem that numerous individual components need to be ordered, installed and matched to one another. This can be performed faster and easier with premounted and preconfigured Safety Sensor Sets, such as the CPSET from Leuze electronic. J. B. Maschinen- und Anlagenbau GmbH has been able to experience this, too. J. B. Maschinen- und Anlagenbau, based in the northern German town of Lamstedt, has produced machines and systems for transport and handling in the wood industry since 1997 (Figure 1). Because these highly efficient systems contain various hazard locations, they must be appropriately safeguarded in accordance with the European machinery directive. In this regard, Up to now, this was accomplished by ordering various components—in some cases, even from different suppliers— and then, with great effort, connecting them to create a safety system. This considerable effort associated with the installation, alignment and integration of the safety technology into the switch-off circuit of the machines was impetus for J. B. Maschinen- und Anlagenbau GmbH to shop around for a complete system for the safeguarding of access points with material infeed. General Manager Mr. von Holten said in this regard: “We need economical, easyto-mount and reliable complete systems.” The requirements on such a system included, among others: - Complete system with integrated muting control - Simple integration in the safety circuit of the machines and systems - High availability, even in noisy environments The core element of CPSET is a COMPACTplus muting transceiver or a Multiple Light Beam Safety Device of type 4 acc. to IEC/EN 61496-1 or SIL 3 acc. to IEC 61508. The CPSET-M24 Safety Sensor Set includes the muting transceiver and is used for 2-beam access guarding with 4-sensor sequential muting. The set is preconfigured. Nevertheless, adaptation by means of switches in the sensor or via the SafetyLab PC software are generally possible. Page 13 One order—everything is delivered ready for use The CPSET-M24 used by J. B. Maschinen- und Anlagenbau includes, in addition to the COMPACTplus muting transceiver, the device columns, Deflecting Mirrors, muting sensors, mounting brackets, connection cables and the display and control unit (Figures 3 and 4). This operating box has a Figure 2: CPSET in a handling system for the wood industry. reset button for the start/restart interlock and for overriding following a muting fault (muting restart/ override). It also includes a LED indicator and is prepared for direct mounting on the hard guard. The set, with all necessary components, can be ordered by specifying just a single CPSET part no.—instead of many individual items. This simplifies the ordering process immensely. Everything needed arrives on the same day—premounted and ready for use. The customer-specific presetting of the “intelligent” muting transceiver, i.e. configurable for various application cases, effectively prevents false alarms caused by interference, such as wood shavings or gaps in the muting object. With its secure relay output, the system can easily—and with no additional costs for safety relays—be integrated in the switch-off circuit of the machine. At J. B. Maschinen- und Anlagenbau, CPSET-M24 ensures that access safeguarding can be put into service quickly out-of-the-box and that a safe system with high availability is delivered to the end customer. The good cooperation with the Leuze electronic field staff has resulted in the CPSET-M24 being adapted to meet the specific requirements of the customer. The system is now used both quickly and trouble-free as standard access guarding by J. B. Maschinen- und Anlagenbau. Mr. von Holten summarized this as follows: “With the CPSET series, Leuze electronic has brought an economical solution to the market for the customer.” Figure 3: Detailed view of the UDC device column with muting transceiver (in the column) and mounted MMS Muting Mounting System, including prewired muting sensors. Figure 4: CPSET-M24 with display and control unit (right). Page 14 On track with trend-setting sensors Laser scanner ROD 4 unlocks new dimensions for driverless transportation systems Driverless transportation systems (FTS) perform transport tasks economically and fully automated. With the innovative ROD 4 laser scanner from Leuze electronic, SIEMENS guides such systems by means of 3D laser navigation on the hall ceiling, thereby reaching a new dimension: both navigationally and economically (Figure 1). The cost effectiveness of driverless transportation systems (DTS) stems primarily from the automatically operated transport vehicles, i.e. with no human operator. However, depending on the navigation system that is used, structural measures requiring high planning effort are usually necessary in the surrounding environment. These may be carriages, induction loops or magnets in the floor, or laser scanners that normally scan over an area, i.e. two dimensionally, and require reflectors on walls, shelves, machines etc. The possible flexibility with respect to changes of Figure 1: With innovative transport tasks 3D laser navigation on the hall is more or less ceiling, SIEMENS driverless limited. corridor supply vehicles operate Furthermore, reliably and safely. production-related or structural changes in the surroundings, such as modified machines and systems or relocated shelves, interfere with the transport process. The laser scanner ROD 4 by Leuze electronic in the new Autonomous Navigation System ANS by SIEMENS (Siemens Division Industry Automation and Drive Technologies) unlocks new dimensions for driverless corridor supply vehicles. This applies both to the spatial plane used for navigation, namely the hall ceiling, as well as to the cost effectiveness, achieved through lower installation costs, as no navigation aids need to be installed on the floor, walls or system parts. Last, but not least, ANS also facilitates maximum flexibility for route changes in today’s rapidly changing production environments. Figure 2: ROD 4 laser scanners from Leuze electronic, with their laser distance measurement technology for 3D contour measurement, serve as the basis for the innovative Autonomous Navigation System (ANS) from SIEMENS. Spatial representation of the hall ceiling For the navigation of driverless transportation systems, the ROD 4 laser scanner is mounted on a swivel motor on the top of the vehicle (Figure 2). The fast, pulse propagation time technology of the ROD 4 enables the detection of 3D profiles that can be generated by means of swiveling and a linear forward motion of the vehicle relative to one another. This creates spatial representations of the surrounding environment - in this case the hall ceiling - which then serve as the basis for free navigation. “The new 3D laser navigation system can be installed on a wide range of different types of indoor vehicles, from high-lift trucks to industrial trucks,” explains engineer Walter Beichl, the project manager responsible for ANS at Siemens. “We are able to attain a navigation quality that is sufficient for most logistics requirements,” Beichl adds. Absolute operational reliability included Compared to conventional DTS installations, the installation effort associated with the Autonomous Navigation System with the ROD 4 laser scanner is much lower. This system requires absolutely no structural measures and can be quickly commissioned, because the route is defined by means of 3D laser navigation on structural contours present in the vicinity of the hall ceiling. Even subsequent route changes can be integrated at short notice and in just a few minutes. Even the integration of individual vehicles into existing productionand logistics processes is an economical possibility, independent of the current production layout. Flexibility in a future-proof logistics plan is, thus, no longer bound by any limits. Page 15 Always well positioned! Light-section sensors LPS in rails of a robot application for door manufacturing To be also able to determine 3D gripping positions even for large-sized objects, Leuze electronic has deliberately designed its LPS series light-section sensors for a large measurement range of 200 to 800 mm. The compact construction of the sensor permits its integration directly into the grabber, which makes the LPS series the ideal solution for robot applications for special-purpose machine manufacturer G. Kraft Maschinenbau. Often, the stacked doors are not all of the same model, and may not lie exactly on top of each other. The stack also decreases in height each time a door is grabbed. This means that the robot needs an intelligent position detection system for grabbing, such as an LPS made by Leuze electronic. “The robot see within a short distance and must position itself within just a few millimeters. The LPS light-section sensor is exactly the right product for this purpose” says Berthold Sudahl, head of the robotics department at G. Kraft Maschinenbau. Line profile sensors (LPS) measure the dimensions or the due to a lack of alternatives. These sensors are used wherever products are on a pallet or have a large variation in position. In addition to its 160 × 74 × 56 mm compact construction, the LPS 36 is characterized by a response time of 10 ms, a 600 mm laser line at 800 mm distance and an Ethernet interface. With a 100 Hz measurement rate, the sensor achieves a resolution between 1 and 3 mm; its transmitter and receiver are accommodated in a single unit and are already adjusted. The sensor has many advantages for G. Kraft Maschinenbau: It has no moving parts and permits easy G. Kraft Maschinenbau GmbH is based in Rietberg-Mastholte, Westphalia. It manufactures specialpurpose machines for the wood processing industry and the production of radiators, wooden flooring, sandwich panels, packaging, doors and frames. For the embedding of fittings into doors with the CNC fitting embedder TCF 70, the unmachined doors are manually stacked on a roller conveyor.

Page 16 Moving bridges with Leuze electronic ODSL laser sensors measure distances as the Oakland Bay Bridge is moved within the scope of an extensive repair Leuze electronic BV of Waardenburg (Netherlands) and Syrinx Industrial Electronics, also of the Netherlands, play an important role in the construction of the Bay Bridge in San Francisco in the U.S. state of California. The Oakland Bay Bridge connects Oakland and San Francisco. Every day, 300,000 vehicles travel over this important, five-lane, doubledeck toll bridge. Following the severe earthquake in San Francisco in 1989, it was decided to replace part of the link between Oakland and San Francisco with a new bridge. To realize this connection, it was necessary to temporarily move part of the old, existing bridge (expected to be completed by 2013) in order to make space for the construction of the new bridge. The final construction step in the realization of this detour was the separation of a 100 m long, 3200-ton section and the subsequent moving of this section of the bridge. Afterward, a new, 3600-ton bridge section was pushed into the resulting gap to complete the detour section—all at a height of 50 m. This work was performed on Labor Day weekend in 2009 and had to be completed within three days. In the spring of 2009, Syrinx Industrial Electronics was contracted by Mammoet, the well-known Dutch specialist for transport and assembly solutions in the heavy-load sector, to develop a central monitoring system for this project. The system was to allow all movements to be displayed on a large, 42-inch screen as the bridge parts were moved. time. Affixed to a mounting plate, the Leuze electronic sensors could be easily applied and positioned through the use of strong magnets (Figure 1). Measurement of both small and large distances while moving the bridge During the move, the bridge was pushed upward at four points approximately 30 cm and then moved laterally by means of hydraulic winches with a stroke of 1.5 m (Figure 2). The height and position of the various hydraulic winches were converted to 4 to 20 mA measurement signals with the aid of the Decision for laser distance sensors from Leuze electronic A total of 31 laser distance sensors and 16 pressure sensors were used. For the monitoring of this challenging project, Syrinx Industrial Electronics chose ODSL laser distance sensors from Leuze electronic. Decisive here was their precision, robust design and the display, which allows measurement values to be read on the spot. As a result, it was not necessary to constantly run back to the central laptop to make adjustments during installation. Considering the large distances, this saved considerable Figure 1: The mounting plate with the sensor is attached and aligned by means of a magnet (source: Syrinx Industrial Electronics, www.syrinx.nl) Page 17 Leuze electronic ODSL 96B laser distance sensors. The horizontal movement was over a distance of approx. 30 m and was measured with Leuze ODSL 30 laser distance sensors. This model was chosen on account of its RS485 output. Syrinx Industrial Electronics constructed a converter box for this output to convert the RS485 information to an exact, 16-bit analog signal of 4 to 20 mA. In this way, it was possible to attain even greater precision over the entire measurement range up to 50 m. In addition to the converter boxes, Syrinx Industrial Electronics also developed eight measurement boxes to which all laser sensors and the used pressure sensors could be connected (Figure 3). Together, all of the measurement boxes formed the complete measurement network that was connected to the laptop. The laptop was then connected to the 42-inch monitor, on which the processes could be Figure 2: The distances during the bridge movement are visualized, as Syrinx measured by the ODSL 96B (source: Syrinx Industrial Industrial Electronics Electronics, www.syrinx.nl) also programmed a solution for the complete visualization for this project (Figure 4).

Projects involve the development and production of customer-specific hardware and software. All necessary steps, even series production, take place inhouse. Syrinx Industrial Electronics specializes in the area of industrial weighing technology and interfaces. The company was present onsite during the entire Bay Bridge project and constructed the measurement system together with its client Mammoet on location. This is only one of many projects that the Dutch engineering firm has realized in cooperation with Mammoet. The next projects are already in the planning stage. Here, too, Syrinx Industrial Electronics will again use Leuze electronic sensors. www.syrinx.nl www.mammoet.com Figure 4: Syrinx Industrial Electronics handled all visualization (source: Syrinx Industrial Electronics, www.syrinx.nl) Page 18 中国欢迎您! Matthias Höhl is the director of our subsidiary in China, which he founded back in 2005. After operating for 5 years in a rapidly growing country, it is time to report on some interesting developments of the company, the country and its people. China has changed extensively, and who would be in a better position to talk about it than someone who has lived in China for the past 10 years? . contact Good day, Mr. Höhl. To start, could you please briefly introduce yourself to our readers and tell us how you came to Leuze electronic in China? . It’s a pleasure. 40 years ago, I was born near Frankfurt. After an apprenticeship as a communications technician, I studied Electrical Engineering and started my career as product manager in a mechanical engineering company. I got to know international business early on through numerous travels, leading me to Asia in particular. Since 2000/2001, I live here in China, with intermediate stations in Hong Kong and Taiwan. My wife was born in Taiwan and my son in Hong Kong, I think you can well and truly call this an international family! In 2005, I founded a new company for Leuze electronic in China. Having gained experience in mechanical engineering, the transition to automation products wasn’t that hard. Höhl . contact How has Leuze electronic developed in China until now? . Leuze electronic started in 2003 with a representative’s office. After establishing our wholly-owned Höhl subsidiary Leuze electronic Trading (Shenzhen) CO., LTD in September 2006, we progressed to a team of 15 staff in Shenzhen, Shanghai and Beijing. Today, there are over 40 “sensor people” in China. I would like to mention in particular our aim to provide the same technical competency in China as we do in Europe. Professional consulting and finding individual solutions for the customer are always top priority. . contact You assemble locally for the Chinese market? . Yes, the first photoelectric sensors and scanners of the 318 Series were assembled in China in May 2007. Starting with the simpler models, we now manufacture the entire range. I am very proud that we have not just managed to maintain the original quality, but that we were even able to improve on it. This requires detailed goal setting, of course, maintaining specifications and continu- Höhl G re a t W a ll o f C hin a ous monitoring of the quality. This applies in particular to purchasing parts and materials. As in Germany, we concentrate on the final assembly and function test of the sensors. . contact What role does ‘Made in Germany’ still play in China? . In China, “Made in Germany” is still number 1. German companies can take advantage of this view and improve their positioning against products from other countries. It still applies: Products from Germany are of high quality and robust, but unfortunately also expensive. I would like to see the Chinese appreciate the quality more and hope that this will improve over the coming years. Höhl Fo rb id de n Traditional Chinese clothing Page 19 IN SIDER TIP Shenzhen . contact On which industries do you focus your attention and how will they develop in the next few years? . The packaging technology, intralogistics, and the automotive industry show enormous growth potential in China. We hope for the biggest growth rate in packaging technology as the shopping habits of the Chinese change increasingly. In the past, food was grown in the backyard or bought daily on the market. Today, the supermarket is the norm. Firstly, this leads to an immense increase in packaging, and secondly products need to be stored and the flow of goods must be managed logistically. This requires distribution centers with high-bay warehouses, leading us to our second industry, the intralogistics. Chinese salaries increase continuously. 10 years ago, the focus was on owning a flat, today it is on owning a flat and a car. This development is extremely rapid and since last year, China is the largest car manufacturer in the world. In the city of Shenzhen alone, 1,000 new cars are registered each day, with an increasing trend. So Höhl far, however, only 10 – 15% of the population live in the metropolitan and industrial areas and can afford this “luxury”—we now have over one thousand billionaires in China! The local market is just beginning the journey, certainly the saturation will occur only in a few years. . contact What are the particular challenges in the Chinese market? . China is a large country— and every day, this is the biggest challenge for our team. The promotion of the provinces in the hinterland and the low salaries that still prevail there increasingly attracts industry there. The biggest challenge is to follow and serve the market, which requires the right number of sales representatives and good regional business associates/distributors. The start of each discussion is about technical solutions, but also about the price. Our trained staff always offer the customer the ideal solution under both price and technology aspects. The need to deliver products with higher quality increases the demand for hightechnology products in China. In combination with products adapted to the local market, this leads to a very good situation for us in the near future. Höhl . contact Are there particular things one should take into account when traveling to China? . China has changed. The particular features that Höhl Ci ty in Be ijing Sk ylin ng e of Ho ng Ko Shenzhen used to be a small fishing town known as “The kingdom of the last Chinese leader Deng Xiaoping.” Founded in 1979 for experimenting and playing with capitalism using the parameters of Chinese socialism, the total area today is 1,948 square kilometers with a registered population of about 12 million. The summer is exceptionally long (about six months) and warm (up to 38°C). The temperatures during winter rarely fall below 10°C. With a blue sky and 25°C, the months of November and December are best for visiting Shenzhen. Accommodating 56 different Chinese ethnic groups, the city offers a wide range of food and drinks. My top location for relaxing with exceptional local food: Laurel Restaurant: 1F. Portofino Club House • Overseas Chinese Town • OCT, GD China ‘I hope I could give you a small insight into Shenzhen—China is just too large for a few words.’ you might know from presentations can often only still be found far away from the big cities. On the one hand, this is a pity since China abandons a part of its culture. On the other hand, awareness about the environment increases. The younger generation in particular has changed many customs and traditions. Spitting and eating dogs is no longer practiced. Nowadays, many Chinese walk their dog or cat on a Sunday. For journeys into the hinterland, I recommend local or professional guides. Welcome to China!
