Abstract

Des magnétisants circonférentiels et axiaux pour un racleur de fuite de flux magnétique sont décrits. Un module de magnétiseur circonférentiel pour un racleur intelligent comprend un arbre central et au moins une barre daimant pour induire un champ magnétique transversal à un axe longitudinal de larbre. La barre magnétique comprend au moins un aimant, et un moyen daffaissement radial vers lintérieur de larbre. Une tête de capteur entre des pôles de circuit au niveau de chaque extrémité polaire de laimant surveille le flux magnétique. Un module magnétiseur axial comprend un arbre central et au moins une barre magnétique pour induire un champ magnétique coaxialement à un axe longitudinal de larbre. Des aimants de polarité opposée sont disposés de manière circonférentielle autour des extrémités de larbre central. Une tête de capteur entre des pôles de circuit au niveau de chaque extrémité polaire surveille le flux magnétique. Larbre central dun magnétiseur circonférentiel ou dun magnétiseur axial peut comprendre une articulation reliant un module racleur intelligent supplémentaire.
