Abstract:
1. Load-cell for signaling the magnitude of a force, wherein: the load-cell includes a saucer; the saucer includes a chunky outer-ring; the saucer includes a thin disc, which extends radially inwards from the outer-ring; the arrangement of the load-cell is such that when an axial load is applied to the disc, the load-cell being supported at its outer-ring, the disc deflects in a conical deflection mode; the disc has an oversurface and an undersurface; the outer-ring projects axially, beyond the undersurface of the disc, whereby the saucer defines and includes an annular recess under the disc, inside the outer-ring, termed the gauge-recess; the load-cell includes a plurality of strain-gauges; the strain-gauges are located on the undersurface of the disc, and within the gauge-recess; the strain-gauges are secured to the undersurface of the disc in such manner as to sense strains induced in the disc due to conical deflection of the disc; the load-cell includes a conductor, for conducting signals indicating the sensed strains to a receiver; the load-cell includes a fixing-flange, which extends radially outwards from the outer-ring.
