Abstract
A pressure sensor header uses a layered assembly of a first and a second metal layer with an intermediate ceramic layer having a radial surface groove providing a fluid passage between a peripheral fluid port and a hole extending through the first layer between the groove and an outer surface of the first layer. A plurality of electrically conductive pins are arranged to extend through the layered assembly and are sealed to the upper and lower metal headers with glass seals to provide a fluid-tight seal. The seals on the metal pins provide a means for retaining the layered assembly in a predetermined configuration while the radial groove and the hole through the first layer provide a fluid path to a pressure transducer element supported on the first layer of the header and having an internal fluid path aligned with the hole through the first layer. Electrical connections to the metal pins provide electrical signal paths between the transducer element and associated electrical circuits.
