Another great addition to our lineup of level sensors and controllers, the ProSense CLC series conductive liquid level controllers detect and control levels of conductive liquids (tap water, seawater, sewage, chemical solutions, coffee, ice cream, etc.) in dual-probe pump-up or pump-down applications. These relays compare the value of the measured resistance between the probe and common with the setpoint controlled by the onboard potentiometer. The output relay can control pumps, solenoids or valves to automatically lower, raise or maintain the level of the liquid in the tank. These level controllers pulse the probes with a DC voltage to prevent potential electroplating issues.
