Abstract
A device for detecting pressure of a high temperature pressurized fluid. A sensing element having a diaphragm adjacent to one end and a lead wire outlet adjacent to another end in the longitudinal direction of a rectangular parallelopiped configuration of the sensing element including the diaphragm. Thus, the lead wire outlet is a predetermined distance from the diaphragm heated by high temperature fluid. This prevents the lead wire outlet and the other electrical assemblies from suffering deterioration or misoperation caused by high temperature. The reliability of the pressure detecting device can be improved.
