Differential Pressure Sensors | Setra Systems

A capacitive pressure sensor is a sensor that measures differential pressure using capacitive technology. Capacitive pressure sensors have a thin diaphragm that flexes as pressure is applied. The distance of flex is measured and translated as a pressure reading. This technology allows capacitive pressure sensors to report in near real-time with extraordinary accuracy.
