Abstract
A load sensing structure for a weighing scale deck includes two or more low profile flexure members, each of which is shaped like the letter E with two outer legs secured to the deck and the inner leg to the platform. The latter has twice the bending strength and stiffness of the former. All legs have their ends connected cantilever fashion to either a common base or to one or the other of the deck and platform. Strain gases on one leg provide complementary inputs to a bridge circuit under weight loads but tend to cancel their effects on the bridge circuit under other load conditions.
