Abstract
The measuring cell comprises two systems of transducers (strain gauges) disposed respectively in two regions of concentration of force of the cell, each system comprising a pair of transducers arranged axially within a plane, the angle enclosed between the plane of the first pair and the plane of the second pair being of 60.degree.. This permits the suppression of the third harmonic in the output signal delivered by a bridge in which the transducers are connected. The opposite arms of the bridge comprise, respectively, a transducer of the first and a transducer of the second pair, the transducers of the first pair and the transducers of the second pair being arranged in the cell symetrically with respect to the axis of the cell.
