USP 4.0 250 (Ultrasonic Positioning Sensor)
The USP 4.0 250 Ultrasonic Positioning Sensor for distance measurement makes it possible to detect objects made of dif- ferent materials such as metal, wood or plastic. Only sound- absorbing materials, such as absorbent cotton or smooth slo- ping surfaces, can be poorly detected by the ultrasonic sensor.
The USP 4.0 250 Ultrasonic Positioning Sensor measures the distance to objects without contact. The sensor emits ul- trasonic 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 transmis- sion and reception of the sound pulse.
