Capacitive pressure sensors measure changes in electrical capacitance caused by the movement of a diaphragm. A capacitor consists of two parallel conducting plates separated by a small gap. One of the plates acts as the diaphragm that is displaced by the pressure, changing the capacitance of the circuit.
All welded structure, suitable for measuring many kinds of media;
Isolated diaphragm material: 316L, Hustelloy-C, Monel, Tantalum;
