About Us: http://lowvoltage-product.com/1-3-liquid-level-controller.html

The liquid level controller is equipped with three contacts to start or stop the refilling function of the vessel according to liquid levels sensed by the electrodes (probes). We provide liquid level controllers with different water levels, styles, shapes and sizes.

Voltage: AC 36-380V 50V 60Hz
Operating temperature: -10℃~70℃

Voltage: AC 36V-380V 50/60HZ DC 12V-DC48V
Operating temperature: -10℃-50℃

The three electrodes are connected to the "e1", "e2" and "e3" terminals.

When the liquid level reaches the uppermost electrode (e1), the relay is activated, and the pump starts refilling the vessel. When the liquid level reaches the bottom electrode (e2), the relay is deactivated and the pump stops refilling.

The sensitivity (between the electrodes) is adjustable within a range of 5-100 KQ via the buttons on the front side of the relay.

Top level electrode: Top (e1)
Bottom level electrode: Bottom (e2)
Earth electrode: Earth (e3)
