Working Principle of a Pressure Sensor - Variohm EuroSensor

The capacitance 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. This imbalance is detected in a capacitance bridge circuit and converted to a output current of 4 to 20 mA.

Pressure sensor - Wikipedia

A pressure sensor is a device for pressure measurement of gases or is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed. For the purposes of this article, such a signal is electrical.
