Abstract:
A force-measuring apparatus, particularly a weighing cell, comprising:a stationary part; a load receiver serving to receive a force to be measured; two guides each having a first end and a second end opposite the first end, wherein the first ends are connected to the load receiver and the second ends are connected to attachment areas of the stationary part, respectively; the load receiver being restrained to a mode of parallel motion in relation to the stationary part by the two guides that extend in parallel planes and are rigid in all directions within the planes but movable in a direction transverse to the planes; an adjuster device configured to positionally adjust at least one of the attachment areas in a direction transverse to the planes of the guides, the adjuster device having an arm extending substantially parallel to the planes of the guides and pivotally connected to the stationary part so as to be rotatable about a pivotal axis; the pivotal axis being substantially parallel to the planes of the guides and substantially perpendicular to the arm; an adjusting member configured to tilt the arm about the pivotal axis by acting on an adjustment area of the arm; and the attachment area being located on the arm between the adjustment area and the pivotal axis and wherein the distance along the arm from the adjustment area to the attachment area is at least as long as the distance from the attachment area to the pivotal axis and wherein, when the adjustment area is positionally adjusted by a given amount by tilting the arm with the adjustment member, the attachment area is displaced by an amount less than the given amount.
