Abstract

Psychromètre ou capteur de mesure de la teneur en eau d'un gaz en mouvement. Il comprend : une sonde de mesure de température sèche placée directement dans le flux de gaz, une sonde de mesure de température dite humide 7, entourée par une gaine 8 en matériau apte à être imbibé par un liquide, cette sonde humide gainée étant également placée dans ledit flux de gaz, et des moyens de mouillage constitués par des moyens 11, 12, 13 injectant le liquide directement dans la gaine 8 et de façon discontinue. L'invention s'applique notamment à la mesure de la teneur en eau de l'air.
