Abstract
The invention relates to a load receiver for weighing purposes, of the type comprising a stationary upright integral with a frame, a loaded upright integral with a load-carrying plate, and two arms 21 and 22 hinged onto these uprights in order to form therewith a deformable parallelogram. The two uprights and the two arms form an integral unit, the joints being defined by constrictions of the constituent mounting. A capacitor load transducer is formed by a first electrode mounted integrally with the stationary upright and by a second electrode mounted on the parallelogram elsewhere than on the stationary upright. The load receiver is of use notably for commercial balances.
