ABSTRACT:
A load cell stamped from a single plate includes a pair of strain gauges mounted on each lateral edge of the plate and a slot extending between laterally opposite strain gauges. The load cell so formed can be widened to provide increased torsional stiffness and resistance to off-center loading while providing good load cell performance in all other respects. In a low profile scale including the load cell, one longitudinal end of the load cell is connected to a load receiving element and the other fixed to a base plate and ground.
