Abstract

A force-measuring ring includes an annular housing which contains at least one piezoelectric measuring element, and a pressure transmission element which is attached to the housing via inner and outer circular-annular membrane areas. The inner and outer membrane areas of the force measuring ring are situated on opposite sides of a symmetry plane defined by the at least one piezoelectric measuring element.
