Migatron RPS-401A&RPS-426A liquid level switch

RPS-401A,RPS-426A analog ultrasonic sensors are installed in a 30 mm barrel-shaped housing and are completely independent. It is powered by 20-30VDC and has reverse polarity protection. It also has a narrow beam,allowing it to get into tight places. A flat target can be tilted 8 degrees and still be detected. RPS-401A and RPS-426A have 2 short-circuit protected analog outputs,4-20mA and 0-10VDC. These outputs can be easily inverted and scaled over almost any range by adjusting the zero and span controls. For ease of setup,an LED intensity indicator is provided. This LED is green when not detected and turns red when the target is moved into position,depending on the amount of reflected signal returning from the target. These analog ultrasonic sensors can be used as level sensors,loop controls,roll diameters,and many more applications requiring continuous distance measurement.
