Abstract

SE PROPONE UN DISPOSITIVO PARA LA VERIFICACION DE LA POROSIDAD DE LAMINAS DIELECTRICAS, EN PARTICULAR PRODUCTOS DE GOMA, TAL COMO CONDONES (2) CON UN SOPORTE DE COBERTURA, A TRAVES DEL CUAL SE APLICA EL PRODUCTO DE GOMA, Y UNO O MULTIPLES ELECTRODOS (5) EXTERIORES, DONDE EL SOPORTE (1) DE COBERTURA Y LOS ELECTRODOS (5) EXTERIORES ESTAN CONECTADOS A UNA FUENTE DE TENSION Y A UN INSTRUMENTO DE MEDICION ELECTRICO. LOS ELECTRODOS (5) EXTERIORES TIENEN FORMA DE PUNTA, PUDIENDO MOVERSE LOS ELECTRODOS (5) EXTERIORES Y EL SOPORTE (1) DE COBERTURA EN RELACION DE UNO CON OTRO DE TAL FORMA, QUE LA PIEL DEL PRODUCTO DE GOMA PUEDE SER CONTACTADA SUCESIVAMENTE MEDIANTE LOS ELECTRODOS (5) EXTERIORES, MIDIENDO LOS INSTRUMENTOS DE MEDICION EL FLUJO DE CORRIENTE EN CADA ELECTRODO INDIVIDUAL E INDICANDO UN DEFECTO COMO UNA MEDICION QUE CORRESPONDE A UN VALOR DE REFERENCIA PARA EL ESTADO LIBRE DE MATERIAL SIN LA PRESENCIA DEL PRODUCTO DE GOMA.
