Abstract

Una sonda de corrientes parásitas para detectar defectos asimétricos en estructuras axialmente simétricas, que incluye: al menos dos bobinas yuxtapuestas que están en un primer plano y bobinadas de forma que cuando se suministre energía eléctrica a dichas bobinas, produzcan campos electromagnéticos que se opongan uno a otro; y al menos dos bobinas yuxtapuestas que están en un segundo plano y bobinadas de forma que cuando se suministre energía eléctrica a dichas bobinas, produzcan campos electromagnéticos que se opongan uno a otro, espaciándose axialmente el mencionado segundo plano del primer plano y siendo paralelo a éste, y haciéndose girar las bobinas yuxtapuestas aludidas del mencionado segundo plano, en dicho segundo plano, un ángulo con respecto a las bobinas yuxtapuestas indicadas de dicho primer plano.
