Product Description
The reed switch relies on two basic scientific principles namely: buoyancy and magnetism. Buoyancy causes the float (which contains a magnet) to rise with the liquid and magnetism helps open and close the switch. A change in liquid levels raises or lowers the float up or down. The end of the pivot arm (non float side) contains a permanent magnet that can repel the switch magnet (inside the stationary ‘stem’ of the entire structure). When the float magnet moves close to the switch’s stationary stem, the float magnet repel the switch magnet which either opens or closes the Electrical circuit.
The FF Series is a magnetic float level switch specifically designed for mounting on the side of a vessel where float orientation is horizontal. It is suitable for industrial use with a wide range of fluids where the float level switch will operate with fluid density as low as 0.25 S.G..
