Differential pressure switch device responsive to differential pressure and temperature change |
摘要 |
A differential pressure switch device having a flexible diaphragm between two chambers subject to differential pressure, a permanent magnet movable with the diaphragm against a biasing force when pressure differences occur in the chambers, a thermo ferrite combined with the magnet for cooperation therewith, and a reed switch assembly actuated by the movement of the magnet and through the action of the thermo ferrite which becomes magnetic or non-magnetic depending on the temperature.
