Abstract

UN SENSOR DE GAS FORMADO COMO UNA CELDA ELECTROQUIMICA QUE TIENE UN PEQUEÑO NUMERO DE COMPONENTES Y QUE ES MUY BARATO DE FABRICAR COMPRENDE UNOS ELECTRODOS (22, 24) FORMADOS COMO ELEMENTOS PLANARES POROSOS SOBRE UN SUSTRATO (20), SIENDO EL SUSTRATO POROSO TAL COMO PARA PERMITIR LA PENETRACION DEL GAS A LOS ELECTRODOS DESDE EL EXTERIOR DEL SENSOR DE GAS, ESTANDO UNOS TERMINALES (10) DE ELECTRODOS EXTERNOS MONTADOS EN LA PERIFERIA DE UNA CARCASA (4), EN EL QUE EN LA REGION DE LOS EXTREMOS TERMINALES, LOS ELECTRODOS, EL SUSTRATO Y LA CARCASA SON SOMETIDOS A UNA OPERACION DE SOLDADURA CON CALOR Y PRESION, CON OBJETO DE RETENER LOS TERMINALES Y LOS ELECTRODOS EN CONEXION ELECTRICA ENTRE SI MIENTRAS SE BLOQUEA LA POROSIDAD DE LOS ELECTRODOS, CON OBJETO DE EVITAR QUE EL ELECTROLITO SE FILTRE A TRAVES DE LOS ELECTRODOS HASTA LA CONEXION ELECTRICA.
