Operating principle of ultrasonic sensors
Ultrasonic sensors are among the all-rounders in the category of position sensors, as they use ultrasound to detect both powdery, liquid and solid media.
Ultrasound is the sound that is not perceptible to humans because it is above the human hearing frequency. In the case of ultrasonic sensors, the position is detected by the ultrasonic waves, which are reflected by the object to be detected. The transit time of the sound pulse is proportional to the distance. Regardless of many object properties, ultrasonic sensors can reliably detect objects and measure fill levels. Even over longer distances, the sensors detect lattice baskets and flat transparent glass panes.
Ultrasonic sensors are always used when photoelectric sensors reach their limits.
Areas of application for ultrasonic sensors are numerous, for example:
- Positioning and recognising products
- Presence detection of objects and people
- Distance measurement
- Loop regulation
- Level measurement
