    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.
