Description
The sensor of the PMP - 052 level is intended for control 1.. . 4 levels of filling of the tank by means of switching of "dry" contacts at achievement of preset values of level of liquid. The sensor of level can be used in technological systems and units to automatic control of the pumping - over pump or electromagnetic valve - prevention of overflow of the tank - prevention of the "dry" course of the pump and other purposes. -

PMP consists of a guide – the pipe welded on the metal case with cable input and the cover wrapped on a carving. On a guide there are freely moved floats (1 … 4 pieces) which course is limited by stoppers. The principle of action of PMP is based on application of the gerkon located in a guide, changing the state (will close/will open) at influence of magnetic field of the magnet which is built in a float. Further change of level does not lead to the return switching of a gerkon since the course of a float is limited by a stopper.
