Ultrasonic sensors work on a principle similar to radar or sonar, which evaluate attributes of a
target by interpreting the echoes from radio or sound waves respectively. Active ultrasonic
sensors generate high frequency sound waves and evaluate the echo which is received back
by the sensor, measuring the time interval between sending the signal and receiving the echo
to determine the distance to an object.

No other measuring method can be successfully put to use on such a wide scale and in so
many different applications. This device is extremely robust, making it suitable for even the
toughest conditions. The sensor surface cleans itself through vibration, and that is not the only
reason why the sensor is insensitive to dirt. The physical principlethe propagation of sound
works, with a few exceptions, in practically any environment and is suitable for both liquid and
solid applications (e.g. plastics, metals, powders and granular materials).

In automotive and industrial applications, ultrasonic sensors are characterized by their
reliability and outstanding versatility. Ultrasonic sensors can be used to solve even the most
complex tasks involving object detection or level measurement with millimetre precision,
because their measuring method works reliably under almost all conditions.

Typical applications

  • Crop sprayers: Automatically adjusts sprayer to proper height over crops
  • Agricultral harvesters: Detects fill level, automatically adjusts harvester unit to
    proper height
  • Waste / Rubbish trucks: Monitors emptying process for efficiency, contactless
    monitoring of waste container content, rubbish bin recognition, control and speed of
    one or double grabbing / gripper / lifter arm position and operation, control of free
    space during operation
  • Fire Engine / Cherry pickers: Prevents collision of ladder by monitoring the working
    area
