Title (EN) MAGNETORESISTIVE LINEAR POSITION SENSOR
(FR) CAPTEUR MAGNÉTORÉSISTIF DE POSITION LINÉAIRE
(ZH) 一种磁电阻线性位置传感器
Abstract:
(EN) A magnetoresistive linear position sensor, comprising a permanent magnet (1) and a magnetoresistive sensor chip (2); one of the permanent magnet (1) and the magnetoresistive sensor chip (2) is fixed; the permanent magnet (1) and the magnetoresistive sensor chip (2) are in relative motion along a fixed motion path; the sensitive direction of the magnetoresistive sensor chip (2) is a direction perpendicular to the fixed motion path; the magnetoresistive sensor chip (2) senses the change in the magnetic field caused by the change in the relative positions of the magnetoresistive sensor chip (2) and the permanent magnet (1), outputs a voltage signal changing with the position, and converts same into position information by means of signal processing.
(FR) La présente invention concerne un capteur magnétorésistif de position linéaire comprenant un aimant permanent (1) et une puce de capteur magnétorésistif (2); l'aimant permanent (1) ou la puce de capteur magnétorésistif (2) est fixe; l'aimant permanent (1) et la puce de capteur magnétorésistif (2) sont en mouvement relatif le long d'un trajet de mouvement fixe; la direction de sensibilité de la puce de capteur magnétorésistif (2) est une direction perpendiculaire au trajet de mouvement fixe; la puce de capteur magnétorésistif (2) détecte un changement de champ magnétique provoqué par un changement des positions relatives de la puce de capteur magnétorésistif (2) et de l'aimant permanent (1), délivre un signal de tension changeant avec la position et le convertit en informations de position au moyen d'un traitement de signal.
