Abstract

PROCESO DE DETECCION Y DE MEDICION DE GRIETAS EN ESTRUCTURAS METALICAS DE MALLAS. ESTE PROCESO PERMITE LA DETECCION Y LA MEDICION DE UNA GRIETA (14) EN UNA ESTRUCTURA METALICA DE MALLAS QUE COMPRENDE ELEMENTOS ESTRUCTURALES QUE CONSTITUYEN UN CIRCUITO ELECTRICO CERRADO (12); CONSISTE EN RODEAR UNO DE LOS ELEMENTOS ESTRUCTURALES (6) CON UN CIRCUITO MAGNETICO (16) CERRADO; FORMAR AL MENOS UN TRANSFORMADOR ENROLLANDO UN BOBINADO (22, 25) SOBRE UNA PARTE DEL CIRCUITO MAGNETICO PARA CONSTITUIR EL PRIMARIO DEL TRANSFORMADOR, CONSTITUYENDO LA ESTRUCTURA METALICA EL SECUNDARIO DE ESTE TRANSFORMADOR; ALIMENTAR (38, 40A-42A, 40B-42B) CON CORRIENTE ALTERNA O DE IMPULSOS DE BAJA FRECUENCIA EL PRIMARIO DEL TRANSFORMADOR, PARA QUE ESTE CREE LONGITUDINALMENTE EN EL ELEMENTO A CONTROLAR UNA CORRIENTE ELECTRICA DE FUERTE INTENSIDAD; DESPLAZAR UN DETECTOR MAGNETICO (30) A LO LARGO DEL ELEMENTO A CONTROLAR Y MEDIR EL CAMPO MAGNETICO INDUCIDO POR LA CORRIENTE ELECTRICA QUE CIRCULA EN EL CIRCUITO ELECTRICO CERRADO.
