Liquid Level Control Relay

Code : SKR-DIN

Three electrodes are connected to the “e1”,”e2” and ”e3” terminals. When the liquid level reaches the upper level electrode (e1) then the relay energizes its contacts to turn on the pump. When the liquid level reaches the bottom level electrode (e2) then the relay de-energizes its contact and turns the pump off. Sensitivity ( empedance between electrodes) can be adjusted in the range of 5-100 K using the knob on the front side of the relay.
