Abstract
A measuring device is provided with a piezoelectric measuring element which is positioned between two force-transmitting supports and exhibits anisotropic thermal expansion and lateral extension behavior relative thereto in a plane normal to the direction of force application. The piezoelectric measuring element, or the end regions of the two supports adjacent to the piezoelectric measuring element, are divided into several rod-, roller-, or rib-shaped elements, the two supports and the piezoelectric measuring element exhibiting essentially the same thermal expansion or lateral extension in longitudinal direction of the rod-, roller-, or rib-shaped elements.
