RPS-401A-80P Analog Ultrasonic Level Sensor Description
The RPS-401A-80P analog ultrasonic sensor is mounted in a PVC barrel housing and is completely self contained. It is powered by 20-30VDC and is reverse polarity protected. It also has a narrow beam angle which enables it to get into tight places. A flat target can tilt up to 10 degrees and still be detected.

The RPS-401A-80P has two short circuit protected analog outputs, 4-20mA and 0-10VDC. These outputs can easily be inverted and can be scaled over almost any range by means of adjusting the zero (P1) and span control (P2).

For setup purposes an LED strength indicator is provided. The LED is green when not detecting a target. The color can vary from yellow to bright red when detecting a target depending on how strong the reflected signal is from the target. Yellow indicates a weak signal and bright red indicates a strong signal. The frequency of operation for the RPS-401A-80P is 135kHz.

The RPS-401A-80P is constructed of PVC. The barrel measures 30mm x 104mm. A standard 6 foot cable is provided, or a quick disconnect (QD) version is also available.
