COMBUSTION PRESSURE SENSOR AND FABRICATION METHOD THEREOF

摘要

A body of a combustion pressure sensor is divided into two parts, a cylindrical lower body and a cylindrical upper body. A diaphragm and a pressure sensing element are attached to the lower end and the upper end of the lower body, respectively, and a pressure transmission member connects between the diaphragm and the pressure sensing element. The upper body is connected to the lower body to cover the pressure sensing element in such manner that the connection part is disposed remote from the pressure sensing element.
