These ultrasonic sensors evaluate the sound reflected by the object. They detect almost every object and are suited especially for the filling level monitoring of fluids or bulk material or the detection of transparent objects. The sensor detects objects independent from their material, aggregate state, color or transparency. The sensors can be adjusted easily by the 4-digit 7-segment display. Convenient programming and quick diagnosis is possible via the IO-Link interface. The sensor can only be used in reflex mode operation.

Characteristic response curve
Characteristic curves show the position of the center or the front edge of the measured object (100 × 100 mm plate) at the time of switching. Ob = Object Sc = Sonic cone width Standard sonic cone (center of the measured object) Extra-narrow sonic cone (center of the measured object) Standard sonic cone (front edge of the measured object)
