Abstract

EL DISPOSITIVO PARA LA PUESTA EN MARCHA DEL PROCEDIMIENTO, SEGUN EL INVENTO, CONSTA DE UNA FUENTE DE TENSION (5) PARA ALIMENTAR AL PUENTE DIVISOR FORMADO POR LOS DOS CONDUCTORES (1,3) DE UN CABLE ELECTRICO, UN CONVERTIDOR ANALOGICO-NUMERICO CON FIJACION (7), UN ORGANO DE SUJECION DEL CABLE AL DISPOSITIVO, UN CIRCUITO DE ENTRADA DE AUMENTO VARIABLE MONTADO EN SERIE A LA ENTRADA DEL CONVERTIDOR Y UN CONMUTADOR (6) PREVISTO PARA CONECTAR EN EL CURSO DE UNA PRIMERA FASE EL CIRCUITO DE ENTRADA A LA FUENTE DE TENSION Y EN EL CURSO DE UNA SEGUNDA FASE ESTE CIRCUITO DE ENTRADA AL PUENTE DIVISOR. LA LONGITUD CONOCIDA DEL CABLE ESTA FIJADA EN EL CURSO DE LA PRIMERA FASE POR AJUSTE DEL AUMENTO DEL CIRCUITO DE ENTRADA Y LA DISTANCIA A LA QUE SE SITUA EL DEFECTO, ES LEIDA DIRECTAMENTE EN LA FIJACION EN EL CURSO DE LA SEGUNDA FASE.
