Abstract

SE PROPONE UN SENSOR DE MEDIDA ELECTROQUIMICO PARA DETERMINAR EL CONTENIDO DE OXIGENO EN GASES, ESPECIALMENTE EN LOS GASES DE ESCAPE DE MOTORES DE COMBUSTION INTERNA, DEL QUE EL CUERPO DEL SENSOR DE MEDIDA CONSISTE EN UN ELECTROLITO SOLIDO, EJ. ZRO SUB 2 ESTABILIZADO Y DEL QUE EL ELECTRODO EXPUESTO AL GAS A SER MEDIDO ES UN ELECTRODO CERMET RECUBIERTO CON UNA CAPA DE REVESTIMIENTO DE CONDUCCION DE IONES, MUY POROSA DE UN MATERIAL DE BASTIDOR DE SOPORTE SINTERINACTIVO, DE CONDUCCION DE IONES DEL TIPO NORMAL DE ELECTRODOS CERMET Y UNA CAPA PROTECTORA POROSA. LA CAPA DE REVESTIMIENTO POROSA CONDUCTORA A LOS IONES AUMENTA CONSIDERABLEMENTE LA ACTIVIDAD DEL ELECTRODO CERMET.
