ABSTRACT:
A force-measuring cell is designed for a receiving structure having multiple force-measuring cells of the same type. Each cell in the receiving structure occupies a design space whose dimensions, projected into a plane orthogonal to the load direction, is delimited by the design spaces of neighboring and/or is equal to the largest dimension of the cell in the plane. The cell has parallel-guiding diaphragms arranged on upper and lower surfaces thereof. The cell includes a calibration weight arrangement with a calibration weight which can be coupled to the cell, as well as a drive mechanism and a transfer mechanism for guidedly moving the calibration weight. An actuator works together with the transfer mechanism and a piezoelectric element that drives the actuator. The actuator has at least two interacting elements to repeatedly engage and release each other by frictional contact force which occurs during the travel movement in one direction.
