Other Details

The magnetic level switch consists of Polyurethane Foam Float carrying permanent ring magnet and non-ferrous stem carrying one magnetic reed switch in its assembly. This model of SS Float sensor has no rigid mounting arrangement and has flexible connection cable holding the sensor assembly in suspended state. This has an advantage that the level at which the sensor has to operate can be easily adjusted by altering cable length. As the water level varies in the storage tank, the float moves vertically along the stem and when the float reaches the vicinity of reed switch, the magnetic field of the permanent magnet forces the reed contact to close, thereby completing the external electrical circuit.
