Abstract
The invention relates to a weighing sensor (1) for an electronic balance which is based on the principle of electromagnetic force compensation. The flow of force is by-passed across at least two lever arms (8, 9) and around a protruding section (7) of the stationary base and the components of the force compensation system are arranged next to the load sensor (6).

1-18. (canceled)
A weighing sensor for an electronic scale on the principle of electromagnetic force compensation, with elements that extend in a first direction (X), a direction (Y) perpendicular thereto, and a direction (Z) perpendicular to directions (X) and (Y), with at least one electromagnetic force compensation system that comprises a coil (S) or a magnet (M) or a position detection system (P), the weighing sensor further comprising:
- a) a base element section to which parallel guidance elements are articulated that extend substantially along direction (X) and guide, relative to the base element, a load receiver movable in the measurement direction (Y);
- b) at least two levers including a first and a last lever, and at least one coupling element, provided as a series of successively functionally connected elements wherein the elements are formed for transfer or transmission of a load acting on the load receiver and for passing it on to the electromagnetic force compensation system;
- c) wherein a component (M, S or P) of the at least one force compensation system is arranged on a lever arm of the last lever;
- d) wherein at least one component (M, S or P) is arranged closer to the load receiver in the X direction than to the base element section;
- and
- e) wherein the series of levers and at least one coupling element runs between parallel guidance elements around a projecting section of base element in functional effect.
