Abstract

Un procédé consiste à effectuer la magnétisation de l'objet commandé avec un champ magnétique pulsé, la lecture des composantes normales des gradients du champ résiduel de cet objet dans la zone de valeur maximum du champ résiduel, la conversion des signaux lus selon la loi logarithmique, à effectuer leur somme et la conversion de la somme obtenue selon la loi antilogarithmique. Le dispositif comprend des bobines de magnétisation (2) et des capteurs magnétosensibles (4) qui sont connectés par l'intermédiaire de convertisseurs logarithmiques (6) à l'additionneur (7). La sortie de l'additionneur (7) est connectée par l'intermédiaire d'un convertisseur antilogarithmique (8) à la sortie du dispositif.
