Abstract

L'invention concerne un élément sensible muni de jauges extensométriques destiné à équiper un capteur servant à mesurer une force. Cet élément sensible est essentiellement constitué d'une membrane en forme de couronne destinée à être encastrée à sa périphérie à l'embase du capteur et solidaire en son centre d'une pièce de renforcement sur laquelle est appliquée la force à mesurer. La membrane, au lieu d'avoir une épaisseur constante, est usinée de telle sorte que celle-ci soit croissante de la périphérie vers le centre ce qui a pour effet d'assurer une répartition homogène des contraintes. L'invention s'applique au capteur de force notamment à ceux qui sont utilisés dans le domaine du pesage.
