□ Overview

Liquid level control switch 52 by the reed switch and circuit modules, compact, durable. It can be divided by end-use type normal BJ-52 level control switch, ZBJ-52 belt to maintain (memory) type liquid level control switch and GZBJ-52-type high-temperature zone to maintain (memory) type control switch. The liquid level control switch in the form of bundled fixed UHZ-52 or UQZ-55-type magnetic float level gauge on the outside, it is in the same magnetic level gauge system, when the magnetic float moves up and down with the liquid level, the corresponding Reed level position by the magnetic field of the float pull, through the conversion module will change the signal into passive switch signal output, if ZBJ-52 type or GZBJ-52-type signal can be cited to keep until you return sensor signal reaches only release, so you can easily use with various types of instruments necessary to achieve control and alarm purposes.
