Patent ID: 6938491

Claim:
A pressure sensor comprising: a) a housing having a first end and a second end and a bore extending therethrough, the housing adapted to be mounted to an engine cylinder; b) a heat shield mounted in the bore adjacent the first end, the heat shield adapted to be exposed to the cylinder; c) a barrel mounted in the bore adjacent the heat shield, the barrel having a cavity d) a piezoelectric body mounted in the cavity, the piezoelectric body having a first and second surface, the piezoelectric body generating an electrical signal that is indicative of a pressure being sensed; e) a first electrode mounted on the first surface, the heat shield located adjacent the first electrode; f) a second electrode mounted on the second surface; g) a first and second terminal mounted to the housing and electrically connected to the first and second electrodes, the first and second terminals adapted to provide an electrical connection to the electrical signal.
