Ultrasonic sensor AFEs

Enhance your system with ultrasonic sensing solutions for flow, level, proximity, position, imaging and distance measurements

parametric-filterView all products
Ultrasonic sound waves are vibrations at a frequency above the range of human hearing (>20kHz) that can travel through air or fluid mediums. It is possible to measure flow, detect objects, perform concentration analysis, and measure distances using techniques such as time of flight or Doppler without ever making physical contact. Ultrasonic sensors can detect a variety of materials regardless of shape, transparency or color.
