Abstract: A pressure sensor assembly includes a pressure sensor, a pedestal and an electrically conductive header having a header cavity. The pressure sensor includes, an electrically conductive sensing layer having a sensor diaphragm, an electrically conductive backing layer having a bottom surface that is bonded to the sensing layer, an electrically insulative layer having a bottom surface that is bonded to a top surface of the backing layer, and a sensor element having an electrical parameter that changes based on a deflection of the sensor diaphragm in response to a pressure difference. The pedestal is bonded to the electrically insulative layer and attached to the header within the header cavity.
