Abstract: Apparatus is provided for mounting a load cell unit between the fixed support and shiftable force responsive structures of a weighing scale or other force measuring equipment in an improved manner minimizing to a point of virtual elimination the accuracy impairing effects of "side loading" of the load cell unit due to lateral and rotational movements of the shiftable structure relative to the fixed structure caused by spurious factors. The load cell unit is disposed between, and in oppositely engaged type coupling relationship with, a rigid plate and a flexure plate spaced from the latter in a carrier assembly, and the carrier assembly is disposed between, and in oppositely engaged rolling contact type coupling relationship with, opposed portions of the fixed and shiftable structures. The engagement coupling relationship between the load cell unit and the flexure plate of the carrier assembly is also of the rolling contact type.

Abstract: Described is a dual guided-beam transducer provided with constant-strain characteristics by forming the two end sections of each beam with opposed edges that converge towards each other along straight lines crossing at the center of the beam, the strain gages being bonded to the end sections within their opposed converging edges.Two embodiments of the invention are described. One embodiment includes a body mountable to a fixed support in cantilever fashion with the load applied normal to the axis of the support. A second described embodiment is a folded-end transducer of cylindrical shape for accommodating loads applied axially to the cylinder.
