Abstract

LA INVENCION ES UN DISPOSITIVO DETECTOR AUTOCONTENIDO DE NOX. PUEDE USARSE PARA DETECTAR NIVELES DE NOX EN UNA CORRIENTE DE GAS TAL COMO LA QUE SE PODRIA ENCONTRAR EN UN GAS DE ESCAPE DE UN PROCESO DE COMBUSTION Y PARA PRODUCIR UNA SALIDA ELECTRICA MENSURABLE RELACIONADA CON EL CONTENIDO DE NOX MEDIDO. EL DISPOSITIVO DETECTOR DE NOX TIENE UNA CONFIGURACION TAL QUE PUEDE SER FACILMENTE DESMONTADO Y REEMPLAZADO. EL DISPOSITIVO DETECTOR COMPRENDE DOS ELEMENTOS SENSORES UNO DE LOS CUALES ESTA CONSTRUIDO A PARTIR DE UN CATALIZADOR SOBRE UN DISPOSITIVO MEDIDOR DE TEMPERATURA. EL OTRO ES UN DISPOSITIVO MEDIDOR DE LA TEMPERATURA AMBIENTE DE LA CORRIENTE DE GAS. EL CATALIZADOR SE SELECCIONA Y SE CONFIGURA DE FORMA QUE REDUZCA SELECTIVAMENTE EL NOX Y EL CALOR RESULTANTE DE LA REACCION ELEVA LA TEMPERATURA DEL DISPOSITIVO MEDIDOR DE TEMPERATURAS ASOCIADO. EL DISPOSITIVO DETECTOR CONTIENE TAMBIEN UNA FUENTE REDUCTORA DE NOX. EL DISPOSITIVO SENSOR PUEDE SER COLOCADO EN UN VEHICULO MOVIL PARA MEDIR LOS NIVELES DE NOX EN SUS GASES DE ESCAPE.
