USP 4.0 (Ultrasonic Positioning Sensor)
Charakteristische Ansprechkurve The USP 4.0 Ultrasonic Positioning Sensor measures the di- stance to objects without contact. The sensor emits ultrasonic waves. If these hit an object, they are reflected. The resulting echo is picked up by the sensor and the distance to the object is calculated from the time between the transmission and re- ception of the sound pulse.
The USP 4.0 Ultrasonic Positioning Sensor for distance measurement makes it possible to detect objects made of different materials such as metal, wood or plastic. Only sound-absorbing materials, such as absorbent cotton or smooth sloping sur- faces, can be poorly detected by the ultrasonic sensor.
