Abstract:
A force-measuring apparatus, particularly a weighing cell, with a stationary part, a load receiver that serves to receive a force to be measured, and a lever combined in an arrangement wherethe load receiver is coupled to the stationary part independent of the lever so that, in response to the force, the load receiver is movable in relation to the stationary part without being guided by the lever; the lever is connected to the load receiver through a first connector element and to the stationary part through a second connector element, the load receiver and the stationary part each having coupling areas for fastening the first and second connector elements, the second connector element is distanced from the first connector element in a lengthwise direction of the lever in an arrangement that allows a lever ratio to be changed; the second connector element forms a fulcrum axis for a rotation of the lever as the latter transmits a displacement of the load receiver to a lever output area located at a distance from the first and second connector elements in the lengthwise direction of the lever, comprising the improvement that the lever has at least three attachment areas for fastening one of the first and second connector elements, that the attachment areas are located at a distance from each other in the lengthwise direction of the lever, and that the coupling areas of the load receiver and the stationary part are arranged vertically above or below the attachment areas in a common plane with the attachment areas, respectively.
