US.52 is a sensor for the distance measurement of an object without contact. The sensor is able to detect the distance of reels of any kind of material, color and transparence. Fog, dust and impurities in the working environment are not a problem for the detection.
Thanks to the sensor high resolution and small blind spots, US.52 sensor guarantees the highest reliability and the highest precision. To calculate precisely the reel diameter in order to detect the web tension, US.52 can be used both with Re tension controllers or other devices such as PLC.
