Abstract

Un sistema (10) y el método asociado para detectar una discontinuidad de material en un artículo magnetizable (12), que tiene una unidad de sensor (16) que incluye un magneto (18) y al menos un sensor de acoplamiento de campo magnético S. El magneto (18) es soportado a una distancia por encima del riel (12) de modo que las líneas de flujo magnético (22) forman un bucle a través del riel (12). El campo magnético del magneto (18) hace que la superficie (14) del riel (12) directamente debajo del magneto (18) se polarice de manera opuesta al polo del magneto (18) que está frente a la superficie, y las regiones distantes al magneto (18) se polarizan de manera inversa. El sensor de acoplamiento S se coloca y se sostiene en una posición fija respecto al campo magnético, y se encuentra dentro del campo magnético activo del magneto (18). El sensor de acoplamiento S mide el acoplamiento de flujo entre el riel (12) y el magneto (18).
