Zusammenfassung:The invention relates to a load receiver comprising a deformable parallelogram formed from a one-piece structure and a load transducer for detecting the deformation of the parallelogram under the effect of the applied load. The transducer comprises four series of pretensioned strain-gauge wire windings, each arranged obliquely between the two uprights (12, 16) or between the two arms (20, 22) of the parallelogram, so as to form two series of windings (34), the main strands of which are tensioned, and two series of windings (36), the main strands of which are compressed under the effect of the applied load, the four series of windings being connected in an electrical bridge circuit. The invention is used for commercial balances.
