Laser positioning systems

Optical laser positioning systems calculate distances to moving system parts contact-free, quickly and with absolute precision. In cycles lasting just milliseconds, the laser distance measuring system provides the position values required for dynamic control functions with millimeter accuracy using a selection of Industrial Ethernet and fieldbus interfaces. With these sensors, distances of up to 300 m can be calculated with maximum accuracy through the use of the latest signal processors. Borderline situations are detected and also diagnostic data indicated with the integrated, extensive functionality catalog. Repeatability of 1 mm, with tested absolute measurement accuracy from ±2 mm to ±5 mm. With the PROFINET and PROFIBUS variants, a parallel SSI interface is available to directly supply the frequency inverter with position data.
