Abstract

L'invention concerne un transducteur de pression comportant au moins deux capteurs dont les caractéristiques sont sensiblement similaires. Chaque capteur est disposé de façon à être soumis à une pression et leurs sorties sont couplées électriquement de sorte que des erreurs associées à un capteur soient compensées par des erreurs associées à l'autre capteur. Ces capteurs peuvent être des capteurs au silicium sensiblement identiques, formés tout près les uns des autres sur la même tranche.
