Abstract
A pressure sensor for sensing a pressure of a process fluid includes a sensor body having a cavity formed therein. A deflectable diaphragm is positioned in the cavity and deflects in response to a pressure applied to the cavity. An electrode on the diaphragm forms a variable capacitor with the pressure sensor body. The capacitance varies in response to the applied pressure.
