Produced by Meite CompanySpecial alarm switch for magnetic flap level gaugeComposed of reed switches and circuit modules, the structure is compact, sturdy, and durable. It can be divided into BJ-5 ordinary liquid level switch, BJB-25 holding (memory) liquid level control switch, and GBJB-25 high temperature holding (memory) control switch according to their purposes

The liquid level control switch is fixed in a bundled form on the outside of the UHZ type magnetic flap level gauge, so that it is in the same magnetic field system as the level gauge. When the magnetic float moves up and down with the liquid level, the reed switch corresponding to the liquid level position is attracted by the magnetic field inside the float, and the changing signal is converted into a passive switch signal output through a conversion module. If it is BJB-25 or GBJB-25, the signal can still be maintained until the return induction signal arrives before being released. Therefore, it can be easily used with various instruments to achieve the purpose of control and alarm. Each magnetic flap level gauge is equipped with multiple alarm switches.
