The Liquid Level Monitoring Relay is designed for filling or draining monitoring. It has a measuring range of 5 to 100 kohm and features 3 electrodes. This relay operates with a rated control supply voltage of 24 to 240 VAC/DC and offers a 1 CO (SPDT) output with screw terminals. It effectively monitors the liquid levels of conductive fluids and provides protection against dry running for pumps or overflow for tanks. The relay works based on the open-circuit principle. Additionally, the sensitivity can be easily adjusted using the front-face potentiometers.
