Short Range Ultrasonic Level/Distance Transmitter-Switch

This short-range ultrasonic level/distance transmitter switch combines non-contact ultrasonic measurement with switch functionality for level or proximity detection. Ideal for small tanks, vessels or areas with limited distance (dead-band) requirements, it provides accurate, repeatable measurement without physical contact. The device typically includes a teachable or programmable set point, either via buttons or software, with outputs for control or alarm. It handles environmental factors (dust, color, transparency) with minimal effect, making it suitable for liquids or solids, and is built to resist moisture, condensation or moderate temperature fluctuations.

Key Features:

Non-contact ultrasonic sensing ensures no wear or physical interference with the measured medium

Very short dead-band (minimal blind zone) for accurate measurement close to sensor face

Programmable set-point or switch output (e.g. relay or transistor) for alarms or automatic control

Teachable via push-buttons or PC/software for ease of setup

Resistant to optical effects (transparency, color, or turbidity) that disturb optical sensors

Rugged housing for industrial environments, some models with waterproof or sealed enclosures
