Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA DETERMINAR LA CONCENTRACION DE UN GAS EN UNA COLADA METALICA, POR MEDIO DE UN GAS PORTADOR, EL CUAL PUEDE SER CONDUCIDO AL MENOS A UN ANALIZADOR, INDISTINTAMENTE O BIEN PARA SER CALIBRADO POR EL CAMINO DIRECTO, O BIEN A TRAVES DE UN CIRCUITO DE MEDIDA CON UNA SONDA DE MEDIDA INMERSA EN LA COLADA METALICA, POR LO QUE EL GAS PORTADOR ENTRA EN UN INTERCAMBIO DE GASES CON LA COLADA METALICA PARA LA MEDIDA, Y ESTA MEZCLA DE GASES ES CONDUCIDA AL ANALIZADOR. PARA PODER DETERMINAR LA CONCENTRACION DE UN GAS EN UNA COLADA METALICA CON SUMA VELOCIDAD Y DE FORMA MUY PRECISA, ES CONDUCIDO EL GAS PORTADOR PARA UN CICLO DE MEDIDA EN UN SECTOR, TANTO DIRECTAMENTE AL ANALIZADOR PARA SER CALIBRADO, COMO TAMBIEN AL CIRCUITO DE MEDIDA PARA LA DEPURACION Y RECEPCION DEL GAS A MEDIR, DE TAL MODO QUE ESTE DISPUESTO EL GAS A MEDIR POR EL ANALIZADOR, QUE A CONTINUACION EL GAS PORTADOR SEA CONDUCIDO A TRAVES DEL CIRCUITO DE MEDIDA, AL MENOS PARCIALMENTE, AL MENOS A UN ANALIZADOR, Y QUE UNA PRESION PARCIAL COMO UNA PRIMERA EVALUACION PARA LA PRESION PARCIAL DEL GAS A MEDIR, SEA DETERMINADA EN LA FUSION METALICA DESPUES DEL INTERCAMBIO DE GASES CON LA COLADA METALICA.
