Abstract:
1. A weighing sensor for an electronic scale according to the principle of electromagnetic force compensation, with elements that extend in a first direction (X), a second direction (Y) perpendicular to the first direction, and a third direction (Z) perpendicular to the directions (X) and (Y), with at least one electromagnetic force compensation system that comprises a coil (S) or a magnet (M) or a part of a position detection system (P), the weighing sensor further comprising: a) a stationary base element section to which parallel guide elements are coupled that extend essentially along the X direction and guide a load receiver moving in the Y direction relative to the base element; b) wherein at least one of one or more levers and at least one of one or more coupling elements are provided as a series of elements effectively connected one behind the other, and wherein the series of elements are constructed for the transmission or conversion of a load acting on the load receiver and for passing the load on to the electromagnetic force compensation system; c) wherein components of the electromagnetic force compensation system (M, S, or P) are arranged on a lever arm of a selected last lever of the one or more levers; and d) wherein the load receiver has a stop in the Y direction or in the Z direction for the selected last lever of the one or more levers or for at least one component arranged on the selected last lever.
