Abstract

Perfeccionamientos en sondas para la verificación de tubos por corrientes parásitas, especialmente en generadores de vapor de centrales electronucleares, con una cabeza guía que acaba en punta cónica y un cuerpo de bobinas cilíndrico, caracterizados porque entre la cabeza guía y el cuerpo de bobinas está dispuesta una envuelta flexible en dirección radial que está bajo una tensión previa que actúa uniformemente hacia afuera y presenta un diámetro mayor que el cuerpo de bobinas.
