Abstract
A pressure transducer is provided for measuring pressure within a measurand environment, the transducer comprising a header which includes a substantially nondeformable molded housing formed from a first thermoplastic material defining a cavity and first and second openings into the cavity and a resilient diaphragm formed from the first thermoplastic material molded to the housing and spanning the first opening; a pressure sensing device disposed within the housing; and a pressure transfer medium disposed within the cavity so as to couple the diaphragm to the pressure sensing device.
