ABSTRACT:
A pressure sensor is attached to an engine by inserting a cylindrical metal case having a hollow part into an attaching hole formed in the engine in which engine oil flows. An oil passage is formed in the cylindrical metal case, and oil passages are formed in the housing. The pressure sensor is connected to the engine through an oil transmitting pipe and an oil returning pipe in order to radiate thermal energy of a pressure sensing diaphragm and a pressure sensing chip by flowing the engine oil from the engine to the hollow part of the metal case and by returning the engine oil from the hollow part to the engine.
