摘要： Members as an upper fixing screw, piezoelectric element (15), a pressure transmitting member (14) are located closer to region of an engine to be measured and the like than a fitting thread portion of a sensor casing so that a pre-stress on the piezoelectric element can be constantly maintained at a predetermined value, thus enabling pressure measurement with a high degree of accuracy. Further, a projecting portion or a spacer is provided on the backside of a pressure receiving surface (13) in order to ensure the surface contact between the pressure transmitting member (14) and the back surface of the pressure receiving surface, thus preventing the stress from concentrating on corners of the bottom surface of the pressure transmitting member.

摘要： A piezoelectric pressure sensor is provided with a sensor housing including an inner sensor housing (12), accommodating an piezoelectric element (15), and an outer sensor housing (10) threaded to a test article. The inner sensor housing is attached to the outer sensor housing in such a manner that a prestress applied to the piezoelectric element does not change due to an axial strain in the outer sensor housing. The axial strain is produced when the outer sensor housing is mounted to a test article.
