ESS343 Capacitive Pressure Sensing Element
ESS343 Capacitive Pressure Sensing element measure pressure by detecting changes in electrical capacitance caused by the movement of a diaphragm.
The diaphragm can be constructed from a variety of materials, such as plastic, glass, silicon or ceramic, to suit different applications, as for ESS343, we use SS316 as default material to construct diaphragm.
Such capacitive pressure sensing element can be used to fabricate a kind of passive transducer, which converts the non-electric physical quantity into corresponding capacitance. The capacitance is changed to a voltage or current signal, and is then amplified and processed.
Capacitive Pressure Sensing element is utilized where small distance or displacement is to be measured and higher resolution is required.
