Ultrasonic sensors are mainly used in machine manufacturing and process control for distance measurement, as proximity switch or for room supervision.

The proximity type sensors work after the principle of time of flight measurement of sound. The time of flight in air (forth and back) is approx. 6ms per meter. The new innovative ultrasonic fork sensors however work after the principle of sound amplitude evaluation.

Compared to other measuring principles ultrasound is very robust. It passes dirty environment as well, and it is reflected by almost all surfaces. Thus it is independent of material, colour and surface structure of the target to be detected.

On the right one sees the remarkable influence of ultrasonic frequency on the sensor characteristics.
