Abstract
A sensor assembly includes a stainless steel tubular housing. Within the housing is a polyetheretherketone tube and a sensor. An optical fiber joins the sensor to a transmission cable and is fixedly positioned within the tube. A first end of the housing includes a pressure transmission device or bellows and the second end of the housing is crimped about the tube to fixedly position the tube and the sensor within the housing. The sensor assembly is positioned within a channel of a gasket to obtain pressure data from a combustion chamber. This abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
