Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA MEDIR LA OVALIZACION DE UNA CONDUCCION O CONDUCTO DE SECCION CIRCULAR, DE MATERIAL FERROMAGNETICO, ESPECIALMENTE DE UNA CONDUCCION DE ACERO REVESTIDA DE HORMIGON Y MAS PARTICULARMENTE REVESTIDA CON UN MATERIAL ANTI-CORROSION Y CON HORMIGON PROVISTO DE ARMADURAS GRUESAS. EL PROCEDIMIENTO CONSISTE EN DESPLAZAR UN CAPTADOR ELECTROMAGNETICO DE MEDIDA A LO LARGO DE UN CAMINO QUE RODEA A LA CONDUCCION, DE MANERA QUE PUEDA ESTABLECERSE UNA COMPARACION ENTRE LAS SEÑALES EMITIDAS POR DICHO CAPTADOR Y UN CONJUNTO DE VALORES DE SEÑALES PROPORCIONADAS POR MEDIDAS PREVIAS EFECTUADAS SOBRE UNA CONDUCCION ANALOGA.
