The load cell means which in load sensing unbalance of its network produces an output voltage proportional to the weight of the scale loading, is included in the electrical system of the present invention, to function as the activating agency in such system. The load cell means herein employed is of known construction, providing an electrical network normally balanced under zero strain condition of the cell means, and producing an output voltage the magnitude and phase direction of which are directly dependent upon the extent and direction of unbalance of the network as determined in the load sensing function of the cell means, by the application of load to and load removal from the scale load support means. In general, the weighing scale organization of the present invention includes load support means which for example, may be a scale platform and lever system of any well known type, and strain gage load cell means coupled to the load support means for sensing the loading of the support.
