Abstract

La presente invención se refiere a un dispositivo para el análisis de gas dentro de una corriente gaseosa en movimiento, caracterizado porque se compone de un medio analizador ubicado dentro de dicha corriente, capaz de analizar dichos gases contenidos allí; y la combinación de un cuerpo substancialmente poroso ubicado próximo a dicho medio analizador y al medio calefactor; dicha combinación permite substancialmente la penetración de la corriente gaseosa a través de ella, de manera que dichos gases pueden entrar en contacto con dicho medio analizador para ser analizados, impidiendo substancialmente las fluctuaciones del movimiento de dicha corriente gaseosa que afectarían substancialmente y harías inexacto dicho medio analizador, mientras que mantiene dicho medio analizador a una temperatura substancialmente constante, substancialmente independiente de las fluctuaciones de temperatura de dicha corriente gaseosa.
