Weighing apparatus.

摘要

A weighing apparatus has a scale cell (1) and a dummy cell (5), both similarly structured and cantilevered. A load to be measured is applied to the free end of the scale cell and a standard weight (6) is attached to the free end of the dummy cell. Analogue electrical signals from these cells are converted to digital data. The effect of the standard weight (6) is removed from the digital data from the dummy cell (5) to obtain the effect of external vibrations which effect is multiplied by a suitable coefficient dependent on the applied load and subtracted from the digital data from the scale cell (1). <IMAGE>
