Abstract
METODO Y APARATO PARA DETECTAR LA CONCENTRACION DE OXIGENO DE UN GAS. EL METODO COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE APLICA A UN ELECTROIMAN UNA CORRIENTE DETERMINADA PARA PRODUCIR UN CAMPO MAGNETICO EN EL NUCLEO DEL MISMO, CON UNA DENSIDAD DE FLUJO MAGNETICO NOMINAL CONOCIDA; SEGUNDA, SE SUMINISTRA EL GAS AL NUCLEO DEL ELECTROIMAN; Y POR ULTIMO, SE MIDE LA VARIACION DE LA DENSIDAD DE FLUJO MAGNETICO, SIENDO DICHA VAIRACION PROPORCIONAL A LA CONCENTRACION DE OXIGENO EN EL GAS. LA MEDIDA DE LA VARIACION DE LA DENSIDAD DE FLUJO MAGNETICO SE REALIZA CON UN SENSOR DE EFECTO HALL. DE APLICACION EN LA DETERMINACION DEL CONTENIDO DE OXIGENO EN LOS GASES DE ESCAPE DE LOS PROCESOS DE COMBUSTION.
