Abstract
A Weigh-In-Motion force transducer includes a housing profile and a piezoelectric measuring arrangement that generates electric polarization charges from a reaction force acting along a force introduction axis via the housing profile, which includes a tubular part internally defining a cavity containing the piezoelectric measuring arrangement under mechanical prestress along the force introduction axis. The tubular par is configured to be expanded along the force introduction axis by a mounting force acting along a mounting force axis and applied to the tubular part. The configuration of the tubular part in a cross-sectional plane defined by the force introduction axis and the mounting force axis is elliptical in shape with a major semiaxis extending along the mounting force axis and a minor semiaxis extending along the force introduction axis.
