Abstract

PROCEDIMIENTO PARA DETERMINAR LA CONCENTRACION DE UNA SUSTANCIA EN UN MEDIO GASEOSO CON UN SENSOR QUIMICO QUE PRESENTA UNA GAMA DE MEDICION NOMINAL DE LA CONCENTRACION DE LA SUSTANCIA, QUE CONSISTE EN: A) RETIRAR UN FLUJO DE GAS (1) DEL MEDIO GASEOSO (100), B) MEZCLAR EL FLUJO DE GAS (1) CON UN FLUJO DE DILUCION (2) DENTRO DE UN MEZCLADOR (16) PARA OBTENER UN FLUJO DE GAS DE MEDICION (3) EN UNA PROPORCION DE DILUCION AJUSTABLE, C) CONDUCIR EL FLUJO DE GAS DE MEDICION (3) AL SENSOR QUIMICO (20) PARA GENERAR UNA SEÑAL DE DETECCION (22), D) REGULAR LA PROPORCION DE DILUCION DE MANERA QUE LA CONCENTRACION DE LA SUSTANCIA DETECTADA POR EL SENSOR QUIMICO (20) SE MANTENGA DENTRO DE LA GAMA DE MEDICION NOMINAL, E) CALCULAR LA CONCENTRACION DE LA SUSTANCIA PROCESANDO LA SEÑAL DE DETECCION (22), TENIENDO EN CUENTA LA PROPORCION DE DILUCION, CARACTERIZADO POR CONDUCIRSE EL FLUJO DE GAS PROBETA (1) Y EL FLUJO DE GAS DE DILUCION (2) SUCESIVA Y ALTERNATIVAMENTE CON UN CAUDAL VOLUMETRICO DEFINIDO, DE FORMA CICLICA, AL MEZCLADOR (16), Y UN DISPOSITIVO ADECUADO PARA ESTE PROCEDIMIENTO.
