Abstract
En un método de ensayo por corrientes parásitas que comprende utilizar una sonda giratoria para ensayos por corrientes parásitas en donde una bobina de detección se dispone dentro de una bobina de excitación, se reduce un cambio en la sensibilidad de detección (una desviación de la sensibilidad de detección) que cambia dependiendo de la posición rotacional de a bobina de detección. La sonda para ensayos por corrientes parásitas incluye una bobina de excitación EC1, una bobina de detección DC1, una bobina de excitación EC2 y una bobina de detección DC2, las cuales están montadas en un disco DS. La sonda para ensayos por corrientes parásitas se dispone de manera de enfrentar una superficie circunferencial de un objeto a ser inspeccionado T, el cual tiene la forma de un cilindro circular, y el disco DS se hace girar. Luego, la distancia (despegue) entre las bobinas de detección DC1 y DC2 y una superficie de inspección cambia. Por lo tanto, también la sensibilidad de detección de una senal de defecto o falla cambia. Para reducir el cambio en la sensibilidad de detección, la sensibilidad de detección se ajusta mediante la detección de la posición rotacional (ángulo rotacional) de las bobinas de detección DC1 y DC2.
