Abstract
UN ELECTRODO DE REFERENCIA, ESPECIALMENTE PARA UNA CADENA DE MEDICION PARA LA MEDIDA DEL VALOR PH, PARA SU CONEXION A UN APARATO DE MEDIDA ELECTRICO CON LA INCLUSION DE LA CONEXION DE UN AMPLIFICADOR DE MEDIDA, AL CUAL SE LE HA CONECTADO UN ELECTRODO DE MEDIDA ADICIONAL. ELECTRODOS CONOCIDOS DE ESTA CONCEPCION SON EN SU MAYORIA SENSIBLES EN RELACION A LA SUCIEDAD Y NO ESTABLES EN RELACION A TEMPERATURAS Y PRESIONES ALTAS, ASI COMO EN RELACION A SOLUCIONES ACIDAS Y ALCALINAS. EN EL ELECTRODO DE REFERENCIA, SEGUN LA INVENCION, SE CONSIGUE UNA ESTABILIDAD EN RELACION A UNA TEMPERATURA ALTA Y UNA PRESION ALTA, ASI COMO UNA ESTABILIDAD EN RELACION A LAS SOLUCIONES MAS ARRIBA CITADAS, DEBIDO A QUE SE HA PREVISTO UN TUBO DE CRISTAL, CUYO EXTREMO INFERIOR ESTA CERRADO POR UN TAPON COMPUESTO DE CERAMICA POROSA. EL TUBO DE CRISTAL ESTA LLENO DE UN ELECTROLITO Y CONTIENE UN ALAMBRE DE PLATA CLORADO SUMERGIDO EN EL ELECTROLITO, EL CUAL ESTA UNIDO CON UN CABLE. EL TUBO DE CRISTAL ESTA RODEADO DE UNA ENVOLTURA COMPUESTA DE UN MATERIAL CONDUCTIVO. COMO MATERIAL PARA LA ENVOLTURA SE PROPONE ESTER DE VINILO ENDURECIDO CON CLORURO DE POTASIO CRISTALINO SATURADO O POLIETILENO, CLORURO DE POLIVINILO O RESINA EPOXIDO, CADA UNO MEZCLADO CON UN ADITIVO CONDUCTIVO.
