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 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.
