摘要:
A loadcell for a weighing scale includes an elongate beam having mounting and free ends spaced apart along a beam axis to define a cantilever. The beam includes an upper surface spaced above the beam axis, and a lower surface spaced below the beam axis. A central aperture extends through the beam to define a plurality of spaced apart necks. The beam lower surface at the free end is spaced closer to the beam axis than at the mounting end to define a step. And, a plurality of strain gages are mounted to the beam adjacent to the necks for measuring strain thereat. Mounted in a scale housing, the beam free end abuts a housing mounting pad for limiting travel of the loadcell and providing overload protection therefor.
