WEIGHING APPARATUS WITH DEFORMATION GAUGES, PARTICULARLY PERSON WEIGHING APPARATUS

摘要

measuring device with strain gauges, including weighing, characterized by the fact that it comprises: a single bar (1) bonded at its ends (2, 3) with a plate (5), respectively.(7) for receiving and supporting a seat (10) and at least two sets (12, 13) for strain gage attached to the bar.sensitive to the bending of the bar under the effect of the applied load, the sets.in association with the area of the bar, with which they cooperate with the circuit for processing signals from the strain gauges.with the same sensitivity measurement for a load, at least a third strain gauge (14) fixed to the bar.sensitive to the twist of the bar under the effect of the applied load, and a circuit for processing signals from the three sets of strain gage.including means for combining the signals so as to remove the outgoing signal component resulting from the deformation of the torsion bar.
