Abstract
A load sensing structure for weighing has a rectangular deck with four flexure members supporting the deck. Each flexure member has attachment portions secured to the deck and oppositely facing attachment portions secured to a fixed platform. U-shaped flexure intermediate portions have parallel legs or beams that are connected to one another by a rigid base of the U, and these legs are also cantilever connected to the attachment portions. Two strain gages on one such leg are so located that these gages must sense tension and compression to indicate weight in the bridge circuit. If both detect tension or both compression no weight indication will occur.
