Abstract
A pressure sensor assembly for sensing a pressure of a process fluid includes a sensor body having a cavity formed therein and first and second openings to the cavity configured to apply first and second pressures. A diaphragm in the cavity separates the first opening from the second opening and is configured to deflect in response to a differential pressure between the first pressure and the second pressure. A capacitance based deformation sensor is provided and configured to sense deformation of the sensor body in response to a line pressure applied to the sensor body.
