WEIGHING APPARATUS WITH DEFORMATION GAUGES, PARTICULARLY PERSON WEIGHING APPARATUS

摘要

Measuring apparatus with strain gauges, particularly person weighing apparatus, characterized in that it comprises a single bar (1) integral at both its ends (2, 3) respectively with a load reception platen (5, 7) and with a support base (10); at least two assemblies (12, 13) with a deformation gauge secured to the bar, sensitive to the flexion of the bar under the effect of the load applied, those assemblies, associated with the bar area with which they cooperate and with the circuit for processing the signals provided by the gauges, having the same measuring sensitivity for a same applied load, at least a third assembly (14) having a deformation gauge secured to the bar, sensitive to the torsion of the bar under the effect of the load applied, and a circuit for processing the signals generated by said three deformation gauge assemblies, comprising means to combine said signals in order to eliminate in the output signals the component resulting from the deformation of the bar under torsion effect.
