Patent ID: 7596984

Claim:
A force-measuring cell for installation in a receiving structure, as one of a plurality of the same type of force-measuring cells, each force-measuring cell having a force-transmitting device that defines a load direction, such that each force-measuring cell occupies a design space in the receiving structure, each design space having dimensions, projected into a plane extending orthogonal to the load direction, that are delimited by the design spaces of adjacent force-measuring cells and/or correspond to the largest dimension of the force-measuring cell in the plane, each force-measuring cell comprising: parallel-guiding diaphragms arranged on upper and lower surfaces of the force-measuring cell; and a calibration weight arrangement, comprising: a calibration weight which can be coupled to the force-measuring cell; a drive mechanism, comprising: an actuator, having at least two elements which interact with each other through the repeated engagement and release of a frictional contact force which occurs during a travel movement in one direction; and a piezoelectric element that drives the actuator; and a transfer mechanism, co-acting with the actuator for the guided movement of the calibration weight.
