Title (EN) SYSTEM FOR MEASURING A MAGNETIC FIELD COMPRISING A THREE-AXIS SENSOR FOR MEASURING A MAGNETIC FIELD THAT IS ABLE TO MOVE TOGETHER WITH A CARRIER THAT DISRUPTS THE MEASUREMENTS, AND ASSOCIATED METHOD
(FR) SYSTEME DE MESURE DE CHAMP MAGNETIQUE COMPRENANT UN CAPTEUR TRIAXIAL DE MESURE DE CHAMP MAGNETIQUE MOBILE CONJOINTEMENT AVEC UN ELEMENT PORTEUR PERTURBANT LES MESURES ET PROCEDE ASSOCIE
Abstract: front page image
(EN)The system for measuring a magnetic field comprises a main three-axis sensor (1) for measuring the magnetic field that is able to move together with a carrier (2) capable of generating at least one additional magnetic field that disrupts the measurements of the said main three-axis sensor (1), the said three-axis sensor (1) being designed to provide orthonormal measurements for a reference magnetic field in the absence of magnetic disturbances due to the said carrier (2). The system comprises means (5, 6, 7, 9, 4a, 4b) of adjusting the said main three-axis sensor (1) comprising a removable additional sensor for measuring a magnetic field, that is able to move together with the said carrier (2) and positioned on the outside of the said carrier (2) away from the additional magnetic field or fields.
(FR)Le système de mesure de champ magnétique comprend un capteur principal triaxial (1) de mesure de champ magnétique mobile conjointement avec un élément porteur (2) capable de générer au moins un champ magnétique additionnel perturbant les mesures dudit capteur principal triaxial (1), ledit capteur triaxial (1 ) étant adapté pour fournir des mesures orthonormées pour un champ magnétique de référence en l'absence de perturbations magnétiques dues audit élément porteur (2). Le système comprend des moyens de réglage (5, 6, 7, 9 4a, 4b) dudit capteur principal triaxial (1) comprenant un capteur additionnel amovible de mesure de champ magnétique, mobile conjointement avec ledit élément porteur(2), et disposé à l'extérieur dudit élément porteur (2) en dehors du ou des champs magnétiques additionnels.
