Abstract

Un sensor diferencial para la detección de anomalías en materiales conductores de la electricidad que tienen un imán permanente (PM), una primera bobina (Si) con uno o mas primeros embobinados, que corren alrededor del imán permanente y definen un primer eje de bobina (Al), y una segunda bobina (S2) con uno o mas segundos embobinados que corren transversalmente en particular, perpendicularmente al primer eje de bobina. De preferencia una tercera (S3), orientada perpendicularmente al mismo, también es proporcionada. Los componentes de los cambios en el flujo magnético se pueden detectar de forma separada para múltiples direcciones espaciales y ser evaluados. El sensor es parte de un sistema de inspección, que comprende al sensor y al dispositivo de evaluación (A), que esta configurado para detector de forma separada para cada uno de las bobinas, los voltajes inducidos en los embobinados de las bobinas (Si, S2, S3) del sensor diferencial o de las señales derivadas del mismo, correlacionarlos al aplicar por lo menos un método de evaluación. (Figura 1).
