Capacitive Pressure Sensor Diagram

Capacitive Pressure Sensor Diagram. The capacitive pressure sensor operates on the principle that, if the sensing diaphragm between two capacitor plates is deformed by a differential pressure, an imbalance of capacitance will occur between itself and the two plates. The diaphragm membrane with edges built in, suspended over a sealed cavity on a silicon nitrate substrate.

Any difference in pressure across the cell will cause the diaphragm to flex in the direction of least pressure. However, for the convenience of understanding, if we model the capacitance between two flat electrodes (c = εa/d); Measuring air pressure using a capacitive pressure sensor is a robust and precise technique.
