More Information
Summary:The invention relates to a piezoelectric pressure sensor for measuring high pressures, comprising a housing (1) that can be inserted into a measuring hole and a piezoelectric measuring element (4) arranged between a sensor membrane (5) and the inner housing shoulder (11 a, 11 b), wherein the sensor membrane (5) is arranged on the front side at the housing (1). The piezoelectric measuring element is formed by a single crystal element (6a, 6b) which is tensioned with its base surface (13) and its opposite cover surface (14) between the pressure piston (9) of the sensor membrane (5) and a branched electrode (8) supported at the bearing shoulder (11a; 11b). The sides (7a; 7b) of the crystal element (6a, 6b), which connect the base surface (13) and the cover surface (14) are mostly abuted against positioning sleeves (12a; 12b) arranged in the housing (1).
