Abstract
L'invention concerne un capteur à jauges de contrainte comprenant un pont de mesure implanté sur un support planaire de circuit électronique, le pont de mesure comportant des première et deuxième barrettes de mesure (BD) ayant une même architecture et comprenant chacune un agencement de mesure de déformation (SDD) et un agencement de compensation de dérive (RDD) intégrant une pluralité de jauges de contrainte, les première et deuxième barrettes de mesure étant agencées respectivement sur des première et deuxième faces opposées du support planaire de circuit électronique. Conformément à l'invention, chaque barrette de mesure comprend au moins une section de mesure de déformation (MD) et la section de mesure de déformation comprend au moins une jauge de contrainte de mesure de déformation (RM) ayant un axe de déformation aligné sur un axe longitudinal central (ACD) de la barrette de mesure et un ensemble de jauges de contrainte de compensation de dérive connectées électriquement (RA1, RA2, RB1, RB2) qui bordent spatialement la jauge de contrainte de mesure de déformation, les jauges de contrainte de compensation de dérive ayant chacune un axe de déformation qui est aligné orthogonalement à celui de la jauge de contrainte de mesure de déformation.
