  • Linear displacement sensor apparatus
    Patent number: 6553840
    Abstract: A linear displacement sensor (10) has a capacitive transducer (24) having a flexible diaphragm (24c) disposed in a housing (12) which also slidingly mounts a plunger (18) movable toward and away from the diaphragm. The plunger has a spring seating end slidably received in a hollow tubular button (14) with a coil spring disposed in the tubular button between the spring seating end of the plunger and a spring seat of the button. Movement of the button caused by an element whose movement is to be monitored causes a change in the force applied to the diaphragm which is proportional to the movement of the button to provide a corresponding output signal by means of signal conditioning electronics (28) disposed in the housing.
