Abstract
A pressure port has a diaphragm at one end for exposure to combustion pressure, an electrical connector attached to the other end, terminal blades and a lead frame molded in the connector and carrying an optoelectronic circuit, and a fiber optic assembly between the circuit and the diaphragm. The fiber optic assembly illuminates the diaphragm which reflects light according to its deflection to two fiber elements that carry reflected light to the circuit. The assembly includes a high temperature plastic body and a ceramic tip for temperature isolation to protect the plastic body and the optoelectronic circuit.
