Title (EN) HIGH RESOLUTION CURRENT AND MAGNETIC FIELD SENSOR
(FR) CAPTEUR DE COURANT ET DE CHAMP MAGNÉTIQUE À HAUTE RÉSOLUTION
Abstract:
(EN) A sensor for detecting an amount of current flowing in a wire wherein displacement of a sensing mirror is used in an interferometer to enable determination of the amount of current. The sensor includes a magnetostrictive element located within a magnetic field formed by the wire. The sensor also includes a position sensor that detects a size increase of the magnetostrictive element. In addition, the sensor includes an amplifying device that amplifies the size increase of the magnetostrictive element by a predetermined amplification factor to provide an amplified size increase. Further, the sensor includes a displacement device that displaces the sensing mirror by an amount corresponding to the amplified size increase.
(FR) La présente invention concerne un capteur pour détecter une quantité de courant circulant dans un fil, le déplacement d’un miroir de détection étant utilisé dans un interféromètre pour permettre la détermination de la quantité de courant. Le capteur comprend un élément magnétostrictif situé à l’intérieur d’un champ magnétique formé par le fil. Le capteur comprend en outre un capteur de position qui détecte une augmentation de taille de l’élément magnétostrictif. En outre, le capteur comprend un dispositif d’amplification qui amplifie l’augmentation de taille de l’élément magnétostrictif par un facteur d’amplification prédéterminé pour produire une augmentation de taille amplifiée. En outre, le capteur comprend un dispositif de déplacement qui déplace le miroir de détection d’une quantité correspondant à l’augmentation de taille amplifiée.
