About the RPS-450
The RPS-450 is a self-contained, 120VAC powered, ultrasonic proximity sensor in a 30mm barrel housing. The sensor is range or distance sensitive, which enables the sensor to detect objects only within the desired range and reject objects outside the desired range. The RPS-450 product line features solid state construction including the solid state relay outputs. The sensor operates in the ultrasonic spectrum and is therefore not heard. For initial setup purposes, a built in potentiometer and LED indicator are provided.
The LED indicator illuminates when the ultrasonic wave from the sensor is reflected back to the sensor within the desired range. The sensor provides precise proximity or level sensing regardless of target color, density, or transparency. The sensor is equally effective on liquid, metal, plastic, or glass targets.
