Abstract

L'invention concerne une cellule de charge capacitive. Cette cellule comporte un corps réalisé en céramique et comprenant des bras extérieurs sensiblement rigides et un bras central relativement flexible. Des plaques conductrices du courant électrique sont montées sur les bras et disposées face à face. L'application d'une charge au bras central fait fléchir celui-ci et modifie ainsi l'écartement des plaques. Domaine d'application : balances électroniques, etc.The invention relates to a capacitive load cell. This cell comprises a body made of ceramic and comprising substantially rigid outer arms and a relatively flexible central arm. Electric current conducting plates are mounted on the arms and placed face to face. Applying a load to the central arm flexes it and thus changes the spacing of the plates. Area of application: electronic scales, etc.
