AutomationDirect added new ProSense CLC series conductive liquid level controllers to its line of level sensors and controllers. The CLC series level controllers detect and control levels of conductive liquids (tap water, seawater, sewage, chemical solutions, coffee, milk, etc.) in dual-probe pump-up (fill) and/or pump-down (drain) applications. These controllers compare the measured resistance value between the high/low probes and a common (either the tank wall or a third probe) with the set point controlled by the onboard potentiometer. A wide adjustable sensitivity range is included to meet a large variety of liquid types. These level controllers pulse the probes with a DC voltage to prevent potential electroplating issues and the output relay can control pumps, solenoids or valves to automatically lower, raise or maintain the liquid level in the tank.
