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.

Abstract: A pressure sensor includes a base having at least one high-pressure contact portion and a diaphragm positioned over the base and having an external top surface facing away from the base and internal surfaces facing the base. The internal surfaces comprising a raised perimeter surrounding an interior, a raised central boss within the interior, and a raised boss arm contiguous with and extending from the raised perimeter toward the interior. At least one of the raised boss arm and raised central boss are aligned with and contact a high-pressure contact portion of the base during an over-pressure event.
