Mini Float Level Switch

FCX/FDX Mini Float Level Switch

The FC/FD Series is a mini magnetic float level switch product line that is very cost-effective and compact. As such these magnetic float level switch units are easily installed on small machinery and in areas where very little space is available inside/outside the vessel in which they are installed. FC/FD series is a magnetic float level switch type of product line that is very compact and cost effective.

These mini magnetic float level switch devices operate based upon two scientific principles, buoyancy and magnetism. The float portion of the mini float level switch is designed for a specific minimum fluid density, specific gravity, based upon the volume and weight of the float element.

The float contains a magnet and the stationary stem incorporates a reed switch which opens or closes its electrical contact when the magnetic element in the float comes in contact with the stem. The reed switch reverses its contact state when the magnet in the float element moves away from the stem.
