    Magnetic Float-type level switch

    Magnetic Float-type level switch

      Model Number


    Magnetic Float-type Level Switch(Horizontal mounting type)

    General : level switches are engineered to suit the majority of extreme liquid level control applications.

    Operationg Pinciple

        The magnetic float of a level switch transmits a signal through a solid nonmagnetic wall utilizing the repulsion of like poles principle when the liquid rises and falls.

      This causes the float magnet to impart a snap action on the electric switch elements.

    Reed switch-type float level switch

    Reed switch-type float level switch

      Model Number


    Operating Principle

        The reed switch type float level switch consists of a magnetic float and reed switch as the main components, which decrease with the fluid level between two stop rings, and its magnetic field actuates a hermetically sealed reed switch incorporated in the guide pipe.

        It is the advantage of this principle that there is only one moving part, the float, which this actuates the reed switch with its magnetic field without causing any wear and the reed switch itself is totally isolated from the media.

      Those advantages provide the user with a safe, repeatable, accurate, and high operational reliablity with low maintenance over a long and trouble-free life.


      Fresh water, Sea water, and Low viscosity liquids.
