Abstract: A load-cell balance in which strain gauges are mounted on a recess portion of the flexible arms of the balance. The circuitry for the strain gauges is mounted on a printed circuit board which is fixed to the stationary portion of the balance and extends along the length of the flexible beams. An electrically shielding cover may be provided for the load balance, as well as compensating resistances.

Abstract: A weighing scale with a load cell is disclosed. The load cell is integrally formed by casting and transmits only vertical motions to the strain gauges so tht moment forces induced by off center loads will not cause inaccurate readings. A stopper limits the movement of the load transmission section to prevent excessive beam movements and to prevent the pivot shaft from falling out of the cell. The gauge circuitry includes a temperature compensation circuit and is attached to one surface of the load cell. Blank or runner ribs are formed in the load cell during casting and are later removed by machining.
