Abstract

um sistema (10) e um método associado para detectar uma descontinuidade de material em um artigo magnetizável (12) que possui uma unidade de sensor (16) que inclui um ímã (18) e pelo menos um sensor de acoplamento de campo magnético (s). o ímã (18) é suportado a uma distância acima do trilho (12) de modo que as linhas de fluxo magnético (22) passam através do trilho (12). o campo magnético do ímã (18) faz a superfície (14) do trilho (12) diretamente abaixo do ímã (18) ser polarizada oposta ao polo do ímã (18) voltado para ela e as regiões distantes do ímã (18) se tornam inversamente polarizadas. o sensor de acoplamento (s) é colocado e mantido em uma posição fixa com relação a e no campo magnético ativo do ímã (18). o sensor de acoplamento (s) mede o acoplamento de fluxo entre o trilho (12) e o ímã (18).
