Abstract

La présente invention porte sur un capteur de gradient de champ magnétique (4) qui est pourvu d'une première tête de capteur (1) et d'une seconde tête de capteur (2) qui ont chacune un noyau magnétique (110, 120) auquel un courant CA d'excitation et un courant CC d'excitation sont appliqués et une bobine de détection (11, 12) enroulée autour du noyau magnétique et qui délivrent chacune une tension de détection correspondant à un champ magnétique dans les directions d'extension de la tête de capteur, et d'un circuit de capteur sur lequel est appliquée la tension combinée de la sortie de tension de détection par la première tête de capteur et de la sortie de tension de détection par la seconde tête de capteur et qui émet un signal de détection de gradient de champ magnétique correspondant à la tension combinée. La première tête de capteur et la seconde tête de capteur sont disposées de manière à être séparées et ont des directions d'extension qui sont coaxiales ou parallèles.
