Abstract
A cantilever beam is located under the pan of the scale and carries a strain gauge bridge circuit. The beam has a bore perpendicular to its longitudinal axis. A rigid force transmitting arm is screwed to the free end of the beam and extends back so that a conical peg in the arm projects into the bore. The conical peg engages a rod which transmits a force from the load to be weighed. The beam has two arcuate recesses symmetrical to the bore on its underside. Strain gauge resistors are positioned so that their centers coincide with the thinnest, and therefore maximum bending sections of the beam.
