Description

Verfahren zur Messung des absoluten Feuchtigkeitsgehalts von Luft und Gasen. Bekanntlich kann man mit Hygrometern, die direkt die relative Feuchtigkeit angeben, die absolute bestimmen, indem man die Temperatur mißt und nach der Dampfdrucktabelle die absolute Feuchtigkeit berechnet.Method for measuring the absolute moisture content of air and gases. As is well known, one can use hygrometers that directly measure the relative humidity state which determine the absolute by measuring the temperature and according to the vapor pressure table the absolute humidity is calculated.

Diese doppelte Messung und Berechnung kann man nun, wie gefunden wurde, dadurch ersparen, daß man das Gas durch einen Thermostaten o. dgl. auf einer konstanten Temperatur hält. Die vom Hygrometer angezeigten Werte sind dann direkt dem absoluten Feuchtigkeitsgrad proportional. Man kann auch direkt z. B. ein Haarhygrometer so eichen, daß es dann die absoluten Feuchtigkeitsgrade direkt anzeigt.This double measurement and calculation can now, as has been found, save the fact that the gas through a thermostat o. The like. On a constant Temperature. The values displayed by the hygrometer are then directly absolute Proportional humidity level. You can also directly z. B. a hair hygrometer like this calibrate so that it then shows the absolute degrees of humidity directly.

Es wurde nun ein besonders einfaches Verfahren für derartige, in manchen Betrieben wichtige Messungen gefunden. Das zu mes-. sende Gas wird durch Räume, z. B. Rohrspiralen o. dgl., geleitet, die von einer mit konstantem Siedepunkt siedenden Flüssigkeit umströmt werden. Vor Eintritt in diese Räume wird das Gas auf eine über dem Siedepunkt der Heizflüssigkeit liegende Temperatur erhitzt, das Gas hält dann selbst die Flüssigkeit am Sieden, während es die Temperatur des Siedepunktes annimmt.It has now become a particularly simple process for such, in some Operated important measurements found. To measure that. sending gas is through rooms, z. B. spiral tubes o Liquid flowed around it. Before entering these rooms, the gas is turned over to one The temperature of the boiling point of the heating fluid is heated, the gas then holds even the liquid is boiling while it assumes the temperature of the boiling point.

PATENTANSPRUCH: Verfahren zur Messung des absoluten Feuchtigkeitsgehalts von Luft und Gasen unter Konstanthaltung der Temperatur des Gases oder der Luft vor Eintritt in das Hygrometer, dadurch gekennzeichnet, daß das zu messende Gas über den Siedepunkt der Flüssigkeit erwärmt wird und diese beim Sieden erhält, indem es die Siedetemperatur annimmt. PATENT CLAIM: Method for measuring the absolute moisture content of air and gases while keeping the temperature of the gas or air constant before entering the hygrometer, characterized in that the gas to be measured is heated above the boiling point of the liquid and maintains this when it boils by the boiling point assumes.
