Become a product tester for Panasonic’s measurement sensors
U
sers of measurement sensors now have the possibility to test
Panasonic’s HG-C series exclusively and for free. The aim is to test and evaluate the measurement sensor HG-C, which has been designed for industrial use to measure distances and displacement, in the field. Typical uses for this sensor are automated product lines where products need to be differentiated, identified, checked, measured, or judged. Important criteria for the test are high-speed applications, high repeatability, and object detection under difficult conditions
WORKING TOGETHER TO GET RESULTS Top-quality analogue sensors for measuring should be developed for and together with customers and users. Every newly launched product should meet strict quality standards, offer outstanding features, and fulfil the high requirements of industrial sensors. This challenge is met best by talking directly to the users of the products. For this reason, the R&D departments will be working in close collaboration with product testers in the target group, who provide a valuable and constructive feedback for the development of the sensors. All the findings are analysed and evaluated and then incorporated into the product development cycle. The end results are sensors that are perfectly attuned to the needs of the industry.
WHY BECOME A PRODUCT TESTER? Product testers will learn how triangulation in the field of optical sensors works. You will receive technical support from product specialists on how to solve your application. The aim is that the sensor will undergo extensive tests in real applications under industrial conditions. After the evaluation, the sensor remains in the possession of the tester for free. All European companies or professionals working within the field of industrial production can apply to become a product tester. Applications from people with an adequate technical background or companies with a concrete application which allows them to test the product in the field are also welcome. At the end of the testing phase, the product testers fill out a questionnaire to document and summarise their results and experiences with the sensor. The feedback will be summarized and the resulting ideas, requests, and experiences
will be integrated in the future development process.
THE PRODUCT TO TEST: THE MEASUREMENT SENSOR Built-in measuring technology and quality inspections play an important part in modern industrial manufacturing processes. To optimise processes and to improve product quality, in-line quality inspections have become indispensable - for example, measuring properties like distance, thickness, diameter, and surface contours. The last two decade's progress in laser technology has shaped the development of industrial measuring methods. One important advantage of laser technology is its precision, which traditionally could only be achieved via tactile measuring systems. The trigonometric principle is the
oldest and still most frequent method for measuring distances optically in the industrial sensor technology. The advancement of semiconductor lasers led to the development of measurement sensors suitable for industrial use. Thanks to a visible red laser and an emitting power of less than 1mW within the scope of laser protection class 1 or 2, no special protective measures are required. The complex signal processing of modern laser measurement systems thus meets the precision and speed required by automation technology.
TRIANGULATION MEASUREMENT Up to 10 years ago, PSD (position sensitive devices) were used as detectors in measurement sensors. During the last decade, CCD or CMOS linear sensors have become more and more common. A significant advantage of CCD and CMOS sensors is their ability to read every single
/AUTOMATION
The three models of the HG-C series offer measurement ranges from 30 ±5mm, 50 ±15mm and 100 ±35mm with a typical beam diameter of 10m to 70m. All models are equipped with a red semiconductor laser of class 2 in an aluminium die-cast housing, offer IP67 degree of protection, and have a temperature drift of only 0.03% F.S./°C. You can find more information about the HG-C analogue sensor on the Panasonic website
pixel in sequential order and to measure the amount of light for each cell individually. The use of CCD and CMOS sensors has smoothed the way for implementing measurement sensors throughout industry. They are suitable not only to measure standard objects, but also for demanding applications with complex surface and/or material properties, e.g. highly reflective surfaces, but also highly absorptive materials such as rubber.
THE HG-C SERIES The newly launched HG-C measurement sensors offer high precision with a resolution of 10μm and a response time of no more than 1.5ms. You only need the function keys to configure the sensor and immediately the measured distance will be displayed in millimetres on the built- in four-digit display. Both a digital and an analogue output signal of 0 to 5V are available for integration into the process. Additional digital inputs are used to trigger the sensor, to control the laser power, and to perform zero adjustment. The HG-C series opens up many new
possibilities for industrial automation. For example, the sensor is optimally suited for positioning robot arms, measuring the position of hoops, checking for the presence of very small objects or the overlapping of even the thinnest types of material.
