ABSTRACT:
A weighing module1has a force-transmitting linkage13arranged between the load-receiving portion3of the weighing cell2and the load receiver5, with an overload protection device that precisely maintains its position being an integral part of the force-transmitting linkage13. By means of a positioning element7, 107, 207, the load receiver5is positioned without play relative to the load-receiving portion3in the plane that extends orthogonal to the load direction, and the load receiver5is also guided in the load direction without play. When forces in excess of the pre-tension force of the elastic element8act on the load receiver5, the latter has the capability of being displaced in the load direction and to tip in all directions that are orthogonal to the load direction. The housing part18serves to delimit at least the range of linear downward deflection as well the tipping movement of the load receiver5when the load receiver5is exposed to transverse forces and to overloads. The rotation constraint20is rigidly connected to the load receiver5and engages a housing-connected recess21. To position the load receiver5relative to its operating environment, a positioning device16is provided, whose central longitudinal axis coincides with the central longitudinal axis of the load receiver5.
