The Liquid Level Monitoring Relay is designed for filling or draining monitoring. It has a measuring range of 5 to 100 kohm and uses three electrodes. The relay operates with a rated control supply voltage of either 110-130 VAC or 220-240 VAC. It features a 1 CO (SPDT) output and double-chamber cage connection terminals. This relay is specifically designed to monitor the liquid levels of conductive fluids. It provides protection against dry running for pumps and prevents tanks from overflowing. The relay operates according to the open-circuit principle. One of the key features of this relay is that its sensitivity can be adjusted using front-face potentiometers. This allows for customization based on specific requirements. Overall, the Liquid Level Monitoring Relay offers reliable and precise monitoring of liquid levels, ensuring efficient operation and preventing potential damage or accidents.
