摘要： A piezoelectric pressure sensor which includes piezoelectric measuring elements is inserted in a housing having a membrane element located on the pressure side of the housing. The membrane element has a centered membrane stamp at the centre of a thin annular membrane. The piezoelectric measuring elements being radially disposed outwards from a prestressing element extending essentially along the longitudinal axis of the sensor, which prestressing element passes through the housing base, serves as a lead for the sensor signal and is attached to a pressure body at its end adjacent to the membrane. The centered membrane stamp is attached to the pressure body, and the prestressing element is prestressed against the housing base, having a gas-tight insulating element interposed. Furthermore, the pressure body is provided with a sealing shoulder which fits against a sealing seat in the interior of housing upon destruction of the measuring elements, thus forming a gas-tight zone.
