ABSTRACT:
A load cell assembly which includes a deflectable load cell (11) having strain transducers which measure the downward deflection of the load cell (11) in response to a load. The load cell (11) includes grooves (31) in the lower surface thereof in the vicinity of each end thereof. A rocker pin (33) is positioned in each groove (31), the groove (31) being configured in such a manner that the pin (31) is captured therein, so that the pin (33) in the groove (31) acts in operation to restrain the load cell (11), but so that the pin (31) extends below the lower surface of the load cell (11). The pin (33) is generally barrel-shaped, having its greatest dimension at its center, so that the load cell (11) is supported on a small area (35) of the pin (33), generally about the centerline of the load cell (11). The load cell assembly also includes two end mounts (41) for supporting the respective ends of the load cell (11), each end mount (41) including means for receiving the ends of the rocker pins (33), which extend beyond the side surfaces of the load cell.
