Abstract
Appareil permettant de détecter les anomalies dans un long objet conducteur d'électricité à inspecter. L'objet peut être un pipeline ou tout autre tube creux. L'appareil peut avoir un générateur de champ magnétique et une panoplie de détecteurs espacés autour du générateur de champ. Comme un mouvement relatif, dans la direction longitudinale, est observé entre l'appareil et l'objet à inspecter, le champ (ou flux) magnétique mobile qui passe du générateur de champ vers l'objet à inspecter peut avoir tendance à faire en sorte que des courants de Foucault passent dans l'objet. Les détecteurs peuvent être espacés, sur le plan tant de l'axe que de la circonférence, pour permettre que la variation du flux magnétique, ou la divergence de courant de Foucault, soit détectée relativement à la position axiale par rapport au front d'onde du champ magnétique (ou, de façon équivalente, toute autre donnée connue comme le plan radial du point milieu du générateur de champ), soit relativement à la position circonférentielle autour de la périphérie de l'appareil telle que mesurée à partir d'une donnée angulaire - ou aux deux. Par la suite, le calcul post traitement peut avoir tendance à permettre que des inférences surviennent pour ce qui est de l'emplacement, de la taille, de la forme et peut-être même de la nature des anomalies repérées dans l'objet. Les détecteurs, et possiblement le générateur de champ entier, peuvent être entretenus à une certaine distance de l'objet à inspecter, par exemple par un boîtier scellé qui pourrait protéger les détecteurs et réduire la nécessité ainsi que les coûts de l'entretien. Le générateur de champ peut comprendre deux pôles primaires de nature semblable, maintenus dos à dos sans contact, et peut comprendre des circuits magnétiques secondaires placés pour façonner le flux du circuit magnétique primaire en une forme plus concentrée par rapport à l'objet à inspecter.
