<p>The disclosure relates to a pressure transducer for use in measurement of pressures in the range of 3000 to 5000 psi and above wherein the pressure sensing module (7) is physically separated from the electrical connector (13) by a barrier formed from a material which is less readily deformable under high pressure than the connector. This is accomplished in one embodiment by separating the electrical connector (13) from the pressure sensing element (7) by a metal support ring (31) against which the pressure sensing element bears. In accordance with a second embodiment, the electrical connector is disposd externally of the housing with the pressure sensing element being disposed within the housing and bearing against an interior wall thereof. In accordance with a third embodiment, the housing is formed of two inexpensive members, one crimped within the other, with the pressure sensing module (7) bearing against an interior wall of the inner housing member and the connector being crimped to the system by a flange (15) on the outer housing member. Preferably, a conductor, which is connected to the circuit ground of the electronic circuitry (11) is also coupled to the system ground by crimping it between the housing and the electrical connector during the crimping of the connector to the remainder of the transducer.</p> |
