Abstract: In piecoelectric measuring elements comprising two or more crystal elements that are jointly subject to the mechanical variable to be measured and are provided with electrically conductive electrodes on opposite surfaces located essentially normal to the electric (x) axes of these crystal elements, disadvantages arising from shearing stresses can be prevented by using crystal elements (2) from crystals of point group 32, in which exist two opposite types of enantiomorphism, l and r, in which part of the crystal elements used belong to one of the two enantiomorphic types l or r, and have one of the two absolute orientations of the x-axis, .alpha..sub.1 or .alpha..sub.2, while the remaining crystal elements belong to the opposite enantiomorphic type and have the opposite orientation of the x-axis.

Abstract: In order to reduce the water content in piezoelectric GaPO.sub.4 crystal elements the proposal is put forward that each GaPO.sub.4 crystal element should be cut in its entirety from one uniform growth zone of a GaPO.sub.4 raw crystal bar and should not contain any zone boundaries, and that the piezoelectric GaPO.sub.4 crystal elements should be treated with a dehydrating solution, until an infrared coefficient of .alpha.<1.5 cm.sup.-1 is obtained at a wavelength in the vicinity of 2.0 .mu.m.

Abstract: A transducer comprising a flexible piezoelectric layer as a sensor element for measuring mechanical quantities in hollow bodies, above all pressures in pipes, the opposite sides of this layer being bonded to electrically-conductive contact layers and being connectable via leads to a display and evaluation unit. In order to achieve a high temperature stability in such transducers and to make them suitable for use at temperatures exceeding 80.degree. C., the piezoelectric layer is proposed to consist of wurtzite or sphalerite. One of the electrically-conductive contact layers can be of some heat-resistant, flexible supporting material, for instance flexible metal foil, such as Cu-Be foil, or a sheet of plastic, one or both of whose sides are metallized, and the other electrically-conductive contact layer can be a metal coating applied by evaporation.
