WEIGHING DEVICE HAVING A PLURALITY OF DIGITAL WEIGHING CELLS, WEIGHING CELL, AND METHOD

摘要

The invention relates to a weighing device having a plurality of digital weighing cells (164), each comprising a sensor connected to a force transmission unit (163), each generating a digital measurement value corresponding to a transmitted force at a measurement time point, a data processing device that converts the digital measurement values to transmission units that may be transmitted over a data communications line (20) and transmits the transmission units to a central control unit (18) connected to all weighing cells for analysis of the transmission units, wherein the central control unit (18) calculates a digital combination value based on the transmission units originating from the various weighing cells (164), said combination value representing a weight force with which the weighing device (16) is loaded at a weighing time point, wherein the conversion of the measurement values to transmission units or the analysis of the transmission units comprises a pairing of each converted measurement value with a time value determined by timer means representing the associated measurement time point, the central control unit (18) estimating a chronological progression of force exerted on a single weighing cell (164) from a plurality of such pairs associated with said weighing cell (164) and generates the combination value by combining estimated values for various weighing cells (164) that each correspond to the weighing time point in the estimated force progressions.
