Ultrasonic Sensors

Ultrasonic sensors are used for reliable position detection and precise continuous distance measurement of solids, powders and liquids. They transmit and receive sound waves in the ultrasonic range. The object to be detected reflects the sound waves and the distance information is determined via time of flight measurement. The non-contact detection is independent of colour, transparency, surface characteristics or surface shine of the object. Blister packages in packaging technology or transparent plastic bowls in the food industry, for example, can be reliably detected. Even in operating conditions with heavy soiling, dust or mist the sensors detect objects reliably and without interference.
