Dust Proof Ultrasonic Sensors use ultrasonic waves for non-contact and wear-free detection of a large variety of objects. These Ultrasonic Sensors can detect variety of objects like transparent or opaque, metallic or non-metallic, or of liquid, solid or powdery consistence. These Ultrasonic Sensors can easily withstand spray, dust or rain. Dust Proof Ultrasonic Sensors provide optimum performance for longer period of time.
