The Mobrey ultrasonic liquid level switch with polyphenylene sulphide construction has output type integral SPCO relay (energised when the sensor is wet) and 1-in BSPT dual mount thread. This switch is designed for high or low-level alarm duties to give a voltage-free contact or solid-state transistor output for alarm signalling or as part of a pump control system. It is intended for level detection at a fixed point when liquid fills the gap between the crystals. The supply voltage ranges between 18VAC/DC and 30VAC/DC
Note:
If the liquid to be monitored is flowing, the device should be fitted with the gap inline with the flow. In storage tanks, it should be fitted with the gap vertical unless the liquid is highly aerated when it should be angled.
