Abstract

A force measuring system with at least two load cells (1, 2), which detect and convert partial forces of the force to be measured into a digital output signal, and with an electronic circuit (5), which calculates a total signal from the output signals of the individual load cells according to the amount of the force to be measured and transmits this total signal to another electronic unit (3) for further processing or data output. The electronic circuit (5) is integrated into at least one load cell (2), whereby the hardware requirements are minimized while detection of the measured values is clearly separated from further processing of the measured values. Advantageously the electronic circuit (5) can be integrated into each load cell (2).
