Abstract

Ce capteur de champ magnétique comporte :- un transducteur (60) pour transformer un champ magnétique à mesurer en une grandeur électrique,- un inducteur (68) de réaction apte à rapprocher un champ magnétique extérieur d'une valeur de référence,- un amplificateur linéaire intégré (62) apte à amplifier la grandeur électrique,- une boucle (64) de contre réaction principale cette boucle ayant deux extrémités dont l'une est raccordée à une sortie (94) de l'amplificateur, et l'autre extrémité est raccordée à l'inducteur de réaction.
