Abstract

L'invention concerne un capteur de position angulaire. Elle se rapporte à un capteur qui comprend une partie rotative (14) qui crée un flux magnétique variable, une partie fixe (16) de support de deux sondes (22, 26) ayant chacune une sortie en courant, une première (22) des sondes présentant un courant de sortie ayant des discontinuités au passage à zéro du flux magnétique, la deuxième (26) des sondes étant soumise à un second flux magnétique déphasé de 900 par rapport au premier flux et présentant un courant de sortie qui est une fonction continue du flux magnétique, et un dispositif (30) d'addition des courants des deux sondes. La plage de variation du courant de la première sonde (22) est un peu supérieure à la plage de variation du courant de la seconde sonde (26). Application aux arbres à cames des moteurs.
