Abstract

La présente invention a pour objet un instrument de pesage utilisant un système de pesée par jauges de contraintes du genre comprenant un plateau accouple à une lame flexible équipée de jauges de contraintes montées en pont, suivies d'un conditionneur, d'un amplificateur et aboutissant à un dispositif de lecture électrique ou autre. Ce système est caractérisé par le fait que les extrémités de la lame sont recourbées soit en U vers l'intérieur, soit en S vers l'extérieur et fixées au socle formant le fond de l'instrument.
