Abstract

A.TRANSDUCTEUR MECANIQUE ELECTRIQUE POUR LA MESURE D'UNE PRESSION. B.ENTRE DEUX AIMANTS PERMANENTS QUI SE FONT FACE AVEC LES POLES DE MEME NOM EN FACE DE L'AUTRE, SE TROUVE UN COMPOSANT A EFFET HALL DONT LA DISTANCE PAR RAPPORT A L'UN DES AIMANTS OU PAR RAPPORT AUX DEUX AIMANTS SE MODIFIE EN FONCTION DE LA PRESSION A MESURER. C.L'INVENTION S'APPLIQUE NOTAMMENT A L'INDUSTRIE AUTOMOBILE.A. MECHANICAL ELECTRIC TRANSDUCER FOR PRESSURE MEASUREMENT. B. BETWEEN TWO PERMANENT MAGNETS WHICH ARE FACED WITH THE POLES OF THE SAME NAME IN FRONT OF THE OTHER, IS A HALL EFFECT COMPONENT WHOSE DISTANCE FROM ONE OF THE MAGNETS OR FROM THE TWO MAGNETS CHANGES INTO FUNCTION OF THE PRESSURE TO BE MEASURED. C. THE INVENTION APPLIES IN PARTICULAR TO THE AUTOMOTIVE INDUSTRY.
