PRESSURE DETECTING APPARATUS

摘要

A pressure detecting apparatus is provided to prevent contamination of a pressure sensor by improving the structure of the apparatus. A sensor supporting part(208) has a sensor cell for detecting pressure and a convert part(206) for covering the sensor cell from contaminations. The sensor supporting part(208) has a cylindrical appearance. A sensor cell receiving part(218) is provided in the cylinder. The sensor cell receiving part(218) is connected to the cylindrical structure through a plurality of connection parts(224). Each connection part(224) has a contamination discharging port(222) in such a manner that contamination is enough discharged. The outer surface of the sensor supporting part(208) has four protrusions(226).
