Abstract: A general pressure sensor for an automobile comprising a sensor shell, a silicon piezoresistive sensitive core, a sensor core seat, a signal conditioning circuit, and an automobile electric device interface is disclosed. The silicon piezoresistive sensitive core, the sensor core seat and the signal conditioning circuit are disposed in the inner cavity of the sensor housing. The sensor housing is installed to the automobile electric device interface, and the silicon piezoresistive sensitive core comprises a silicon piezoresistive sensitive element and a glass ring sheet. The silicon piezoresistive sensitive element is welded and fixed to a surface of the glass ring sheet. An insulation oxidation layer is formed on one surface of the glass ring sheet and the silicon piezoresistive sensitive element. The other surface of the glass ring sheet is hermetically fixed to the ring-shape recession surface provided on the sensor core seat. The sensor core seat is hermetically and rotationally fixed to a pressure inlet on the sensor housing, after the inner lead wire on the silicon piezoresistive sensitive core is led to an interposing board provided on one end of the central hole through the other end of the central hole on the ring-shape recession surface of the sensor core seat, and then is led out by the automobile electric device interface via the signal conditioning circuit.
