Abstract

L'INVENTION CONCERNE UN DISPOSITIF POUR LA DETERMINATION DE LA PRESSION PARTIELLE DES VAPEURS D'EAU DANS DES FLUIDES GAZEUX. SELON L'INVENTION, IL COMPREND UNE CELLULE ELECTROCHIMIQUE 1, UNE SOURCE DE COURANT ELECTRIQUE CONTINU 2, ET UN SYSTEME 3 POUR LA MESURE DE COURANT FAIBLE; LA CELLULE SE COMPOSE D'UN BOITIER 1, ABRITANT UNE PLAQUE DE SEPARATEUR 4, TREMPEE D'UNE SOLUTION D'UN ELECTROLYTE FORTEMENT HYGROSCOPIQUE ET INTERPOSEE ENTRE DEUX ELECTRODES INERTES 5, ET DEUX MEMBRANES DE DIFFUSION DE GAZ 7 AVEC UNE PERMEABILITE DEFINIE AU GAZ SEPARANT CES ELECTRODES DE L'ATMOSPHERE AMBIANTE. L'INVENTION PERMET NOTAMMENT LA MESURE DE TRES FAIBLES CONCENTRATIONS EN VAPEUR D'EAU.THE INVENTION RELATES TO A DEVICE FOR DETERMINING THE PARTIAL PRESSURE OF WATER VAPORS IN GASEOUS FLUIDS. ACCORDING TO THE INVENTION, IT INCLUDES AN ELECTROCHEMICAL CELL 1, A CONTINUOUS ELECTRIC CURRENT SOURCE 2, AND A SYSTEM 3 FOR LOW CURRENT MEASUREMENT; THE CELL CONSISTS OF A BOX 1, HOUSING A SEPARATOR PLATE 4, SOAKED WITH A SOLUTION OF A STRONGLY HYGROSCOPIC ELECTROLYTE AND INTERPOSED BETWEEN TWO INERT ELECTRODES 5, AND TWO GAS DIFFUSION MEMBRANES 7 WITH A PERMEABILITY DEFINED WITH GAS SEPARATING THESE ELECTRODES FROM THE AMBIENT ATMOSPHERE. THE INVENTION ALLOWS IN PARTICULAR THE MEASUREMENT OF VERY LOW CONCENTRATIONS OF WATER VAPOR.
