Abstract

MEDIANTE CORRIENTES DE FOULCAULT SE EFECTUAN VARIAS MEDICIONES CON FRECUENCIAS DIFERENTES CUYOS RESULTADOS SE RELACIONAN A POSTERIORI A FIN DE ELIMINAR LOS EFECTOS PERTURBADORES EN LA CONSTRUCCION DE TUBOS. DICHO PROCEDIMIENTO GENERA TRES SEÑALES: LA PRIMERA DETERMINA LOS FALLOS EN LAS ZONAS EL TUBO EXENTAS DE FALLOS O POBRES EN PERTURBACIONES; LA SEGUNDA DETERMINA LOS FALLOS EN LAS ZONAS CON EFECTOS DE PERTURBACION FUERTES, Y LA TERCERA DETERMINA LOS ESFUERZOS FUERTES DE PERTURBACION. ESTAS TRES SEÑALES, QUE SE VIGILAN CONTINUAMENTE Y DE FORMA SIMULTANEA RESPECTO A VALORES DE UMBRAL, PROVOCAN UNA SEÑALIZACION DE FALTO CUANDO SOLO LA PRIMERA SEÑAL, O BIEN LA PRIMERA Y LA SEGUNDA HAN ALCANZADO SUS VALORES DE UMBRAL.
