LK series liquid level controllerDetailed product description：

Overview
The LK series liquid level controller is used as a matching instrument for measuring and top mounted magnetic level gauges. The controller is installed tightly against the magnetic level gauge and is in the same magnetic coupling system as the magnetic level gauge. Under the action of the magnetic float, the reed switch in the liquid level controller is activated to emit a contact opening (closing) signal. The liquid level controller, in conjunction with the corresponding circuit, can achieve level control, alarm and on-site display for various occasions

Precautions
Due to the small current flowing through the on-site switch when using the LK series liquid level controller, in order to ensure the reliability, safety, and usability of the control switch, the control signal can be driven by the UD-1 conversion amplifier to activate the JTX type small universal high-power relay contacts, thereby achieving electrical control and interlocking of the liquid level
