Abstract

Dispositif de surveillance et d'avertissement de teneur en oxygène pour système respiratoire, comprenant un détecteur 76 mesurant la concentration en oxygène d'un échantillon de fluide respirable fourni par une source 130 à une enceinte à travers une chambre 26 qui communique avec cette source par un orifice d'entrée 28 et avec l'atmosphère environnante par un orifice de sortie 46. L'invention prévoit l'inclusion de moyens (soufflet anéroïde 67) pour maintenir dans la chambre 26 une valeur minimale et constante de pression absolue afin de conserver au détecteur sa précision de mesure en dépit d'éventuelles variations de la pression ambiante (par exemple au dessus d'une altitude déterminée). Application notamment aux systèmes respiratoires pour avions.
