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.

摘要： A measuring sensor comprises at least one SAW (surface acoustic wave) element (20) serving as a sensor and identification unit, which is installed in a contactless manner inside a housing part (10) forming, in essence, a coaxial conductor. The housing part (10) is connected to the shield (13) of the connection cable whose signal conductor (12) extends in a contactless manner over a superficial coupling structure of the SAW element (20) without contact. In order to improve the near-field coupling, the coupling structure of the SAW element (20) comprises additively coupling partial structures, which are arranged on both sides of the signal conductor (12) and which, preferably with at least one strip conductor, encircle, at least for the most part, the SAW element (20) in the peripheral area, and which serve as an integrated discharge loop for pyroelectric charges.

摘要： A piezoelectric pressure sensor includes—an outer housing separated by an annular gap from an inner housing, which inner housing is attached to the outer housing on the pressure side. At least one piezoelectric measuring element is positioned between a diaphragm placed on the pressure side of the inner housing and a base part of the inner housing. The inner housing is provided with a massive cylindrical wall throughout whose wall thickness essentially corresponds to the thickness of the adjacent outer housing. In the annular gap between the outer housing and the inner housing a heat-transfer liquid is contained, or in the space between the base part of the inner housing and an interior shoulder of the pressure sensor a heat-transfer spring or bellows is located.
