摘要： A piezoelectric sensor, preferably a pressure sensor, comprising at least two piezoelectric measuring elements placed in a housing, which are clamped between a membrane on the pressured side of the housing and a pick-up electrode electrically insulated against the housing. The piezoelectric measuring elements are fixedly attached to the pick-up electrode by thermo-compression or soldering and together with said pick-up electrode form a compact measuring element stack, which will significantly simplify assembly of the piezoelectric sensor.
