Ultrasonic Proximity Sensors - SU, TU and UHZ Series


SU, UK, UT and TU series round body reflective ultrasonic distance sensors emit a sound impulse and measure the elapsed time of the returned echo signal reflected off of a detected object. The ultrasonic beam is well reflected by almost all materials (metal, wood, plastic, glass, liquid, etc.) and is not affected by colored, transparent, or shiny objects.

UHZ series thru-beam ultrasonic sensors use sound wave technology and are specifically designed for applications with limited mounting space. Thru-beam pair sensors are often the most accurate and reliable sensor configurations.

Ultrasonic sensors are ideal for applications in which the sensed object is made of clear, transparent or varying surface color materials. You can standardize on one sensor for many materials, without any extra setup or sensing concerns.

Flowline ultrasonic liquid level sensors replace float, conductance and pressure sensors and are available with single and multi-function capabilities including continuous level measurement, switching and control.
