Abstract
a. Procédé pour mesurer l'humidité de gaz, de préférence l'humidité de l'air et/ou des paramètres qui lui sont liés, en utilisant de préférence un appareil de mesure de l'humidité au chlorure de lithium, qui comporte un palpeur de température entouré d'un support absorbant imbibé d'une solution saturée de LiCl et, s'appliquant sur ce support, un enroulement bifliaire, ouvert, formant des électrodes, pouvant être connecté sur une source de tension; b. Procédé caractérisé en ce que, à l'aide d'une thermistance servant de palpeur de température, on produit une indication de mesure électrique, qui varie de façon sensiblement linéaire avec l'humidité de l'air, ou avec un paramètre qui lui est lié; c. Appareil applicable dans des installations de régulation.
