Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA LA DETERMINACION CONTINUA DE LA CONCENTRACION DE AL MENOS UN COMPONENTE GASEOSO DE MEZCLAS DE GASES QUE CONTIENEN OXIGENO. EL DISPOSITIVO EN CUESTION TIENE AL MENOS DOS SENSORES QUE SON SENSIBLES A DIFERENTES COMPONENTES GASEOSOS DE LA MEZCLA DE GASES Y ESTAN DISPUESTOS SOBRE UNA BASE COMUN. CADA SENSOR ESTA PROVISTO DE MITADES DE CELULAS ELECTROQUIMICAS CON UN ELECTROLITO SOLIDO EN FORMA DE UN MATERIAL CONDUCTOR DE IONES DE OXIGENO TAL DIOXIDO DE ZIRCONIO INMOVILIZADO EN ITRIO, Y CON LOS ELECTRODOS CONTENIENDO PREFERIBLEMENTE METAL Y/O OXIDO DE METAL, EN FORMA DE PELICULAS FINAS; UNA SEÑAL ELECTRICA DE MEDIDA QUE VARIA CON LA CONCENTRACION DEL COMPONENTE GASEOSO MEDIDO POR EL SENSOR ES PRODUCIDA POR LOS DOS ELECTRODOS DE CADA SENSOR, Y LA BASE ESTA OPCIONALMENTE PROVISTA DE UN ELEMENTO DE CALENTAMIENTO ELECTRICO. SE DISPONE UN CANAL DE DIFUSION PARA LA MEZCLA DE GASES Y SE EXTIENDE LONGITUDINALMENTE DESDE UNA ABERTURA DE ENTRADA; EL CANAL ESTAPROVISTO DE UNA BARRERA DE DIFUSION Y, A LO LARGO DE SU LONGITUD DESPUES DE LA ABERTURA DE ENTRADA, CON UNO, EL PRIMERO, DE LOS SENSORES ANTES MENCIONADOS SENSIBLE AL COMPONENTE DE OXIGENO GASEOSO Y CON AL MENOS UN SEGUNDO SENSOR QUE ES SENSIBLE A UN COMPONENTE GASEOSO DIFERENTE DEL OXIGENO. UNO DE LOS DOS ELECTRODOS DE CADA SENSOR ESTA DISPUESTO EN EL ELECTRODO INTERIOR SOLAMENTE EN EL CANAL DE DIFUSION Y EL OTRO ELECTRODO ESTA DISPUESTO FUERA DEL CANAL.
