ABSTRACT:
A shear beam load cell system (10) for measuring loads applied to a longitudinally extended beam member (12) having a central axis (24) extending in a longitudinal direction (22). Flexure isolation means (26) are formed on opposing longitudinal end sections (28, 30) of the beam member for minimizing strain on a central section (32) of the beam member (12) responsive to load displacements on the beam member (12). A multiplicity of strain gauge members (14, 16, 18, 20) are secured to the central section (32) of the beam member (12). Web flexure means (58) are formed within the central section (32) of the beam member (12) for mounting the strain gauge members (14, 16, 18, 20) to the beam member (12). The shear beam load cell system (10) minimizes stress changes in the central section (32) of the beam member (12) in response to non-measurement loads applied to the beam member (12).
