Ultrasonic sensors

Reliable detection of objects with critical surfaces and highly transparent objects

Sensoren Made in Germany 

Typical Ultrasonic sensors

Ultraschallsensor UMT 30

Ultrasonic sensors may be a useful alternative where optical sensors come up against their physical limits. This applies, for example, for objects with uneven surfaces or under difficult ambient conditions, or with highly transparent media as well as moving,highly reflective liquid surfaces.

Typical uses of ultrasonic sensors are therefore checking the presence of highly transparent foils and measuring the filling levels in liquid containers. A major advantage of ultrasonic sensors is the absolutely reliable background suppression resulting from their sound time-of-flightmeasurement principle.
