スイツチ。 The pressure of the primary side chamber and the secondary side chamber separated by the filter element is introduced through passages, and a mover is provided that responds to the differential pressure between the primary side pressure and the secondary side pressure introduced from these passages, In a filter device that detects clogging of a filter element by detecting the differential pressure based on the amount of movement of the movable element, a diaphragm is used to close the two passages, and the diaphragm and the movable element are interlocked;
A clogging alarm switch for a filter device, characterized in that the mover is provided with a magnet, and a Hall element is provided that senses the movement of the magnet and outputs an on/off signal.
