he Ultrasonic Sensor UH01 / UH01A is designed especially to detect transparent film and photosensitive material in EPC(Edge Position Control)system.

It can detect the edge of a web with high accuracy, not affected by irregularities in the coating near the edge of transparent film and printed patterns, which is conventionally impossible by optical sensors. Combined with Nireco,s controller, an electrical EPC system and electro-hydraulic EPC system can be constructed. The UH01A is a version of our UH01 ultrasonic sensor with a longer internal length(the distance from the sensor center position to the inner side of the casing). Internal lengths of 200mm, 300mm, 400mm and 500mm are available. The internal length of the UH01 is 60mm (fixed).
