<p>A flat, mass-produced, multiple-beam load cell made from a metal plate includes: a load receiving member with a transverse section (4) integral with a load receiving tongue (5); a clamping member (3) having a transverse section (7) and possibly a pair of clamping tongues (18); and two flexure beams (2) connecting the two transverse sections of the metal plate. When a load is applied to the load receiving tongue, the flexure beams bend into symmetrical double-cantilever S-shapes (14), and each pair of sensors (8 & 10, 9 & 11) mounted on the flexure beams produce electronic signals which are equal and opposite each other while rejecting the effect of lateral or eccentric loads. Also disclosed are low profile weighing scales incorporating such load cells.</p> |
