Abstract
A piezoelectric element for incorporation in pressure, force or acceleration transducers, in which at least two piezoelectric flat plates loaded in shear mode are arranged on both sides of a central support and are retained under compressive pre-tension by pressure distribution members bearing externally on the piezoelectric plates; a compression form member provided with a location hole for the support, the piezoelectric plates and the pressure distribution members is fitted over the pressure distribution members by direct or indirect shrinking the pressure distribution members are preferably made of two exact fitting cylindrical segments transmitting the tension forces evenly over the piezoelectric plates.
