The WPS3000plus electronic level differential switch is suitable for automatic level monitoring of conductive liquids in containers, wells, water tanks or the like. The device can be configured as either a refill or as a discharge device with a slider on the front. The liquid level is automatically measured between two water sensors (min. And Max) are held. Upon penetration of water or the reach of a certain level, a relay attracts and switches, for example, mains-operated pumps, valves or warning devices on and off. Suitable for all concrete, plastic or metal memories and installed quickly since all connections are plug-in. Due to the omission of moving float switches it works absolutely disturbance-free. Switching point selectable at any water level The switching output (relay) can be configured as NC or NO contact via switch on the front side. Teledetection up to 25 m over two core line No dangerous mains voltage at the sensor. Operation without operation or monitoring. Very easy an
