Abstract

Procédé et dispositif de mesure de la vitesse d'un objet sans contact. Un champ magnétique est mobile avec l'objet 2. L'objet se déplace latéralement devant une bobine au moins 3 ou 4, de façon que l'axe de cette dernière soit sensiblement perpendiculaire à la direction du mouvement Le signal de tension induit dans la bobine, qui représente la vitesse de l'objet, est mesuré.
