Description

Beschreibung des ileuchtigkeitsmeßgerätes für beliebige Gas-(Luft-) Xemperaturen Dieses Gerät ermöglicht ohne fremde hilfsmittel außer einer elektrischen Stromversorgung die Messung der Feuchtigkeit (Luftfeuchtigkeit) bei beliebigen Temperaturen0 Das Gerät kann als kompaktes Gerät aufgebaut werden. Es kann mit einer für höhere Temperaturen geeigneten Rohr- oder Schlauchverbindung an eine zu untersuchende Kammer oder Rohrleitung angeschlossen werden. Description of the moisture meter for any gas (air) X Temperatures This device enables without any external aids other than an electrical one Power supply the measurement of humidity (air humidity) at any temperature0 The device can be constructed as a compact device. It can be with one for higher Temperatures suitable pipe or hose connection to a chamber to be examined or pipeline.

tber ein Filter (1) wird aus der zu untersuchenden Kammer oder Rohrleitung eine geringe Menge Gas über eine Rohr- oder Schlauchverbindung (2) stetig abgesaugt. Dieses Gas gelangt nun in eine Heiz- und Kühlkammer (3), um es an deren Ausgang auf eine möglichst konstante Temperatur zu bringen. Die Eeiz-und Kühlkammer (3) kann elektrisch beheizt (4) und durch Raumluft an der Oberfläche (5) gekühlt werden. Bei Bedarf kann ein Gebläse (6) diese Kühlwirkung verstärken0 Von dieser ein und Kühlkammer gelangt das Gas in die Xeßkammer (7). Die Gastemperatur in der Meßkammer (7) wird durch die Heiz- und Kühlkammer (3) so eingeregelt, daß für den höchsten zu messenden Feuchtigkeitsgehalt noch keine Kondensation in der Meßkammer (7) erfolgen kann. Die Meßkammer (7) enthält zwei elektrische Temperaturfühler (8) und (9).The chamber or pipeline to be examined is removed via a filter (1) a small amount of gas is continuously sucked off through a pipe or hose connection (2). This gas now enters a heating and cooling chamber (3) in order to exit it to bring to a temperature that is as constant as possible. The heating and cooling chamber (3) can be heated electrically (4) and cooled by room air on the surface (5). If necessary, a fan (6) can increase this cooling effect In the cooling chamber, the gas enters the measuring chamber (7). The gas temperature in the measuring chamber (7) is regulated by the heating and cooling chamber (3) so that for the highest moisture content to be measured, no condensation has occurred in the measuring chamber (7) can. The measuring chamber (7) contains two electrical temperature sensors (8) and (9).

Der Temperaturfühler (9) ist mit einem Gewebestrumpf (11) umgeben. Dieser Gewebestrumpf (11) führt durch einen engen Spalt in eine lmebenkammer (10), die ständig mit Kondenswasser gefüllt wird. Aus der Meßkammer (7) wird das Gas in eine Kühlkammer (12) geleitet, in der durch Kondensation die vorhandene Feuchte als Wasser ausgefällt wird. ueber die Anzapfung (13) wird dieses Kondenswasser der Nebenkammer (10) zugeführt. Die Kühlkammer (12) wird mit einem Peltier-Element (14) gekühlt. Die dem Gas entzogene Wärme wird über einen Kühlkörper (15) an den Umgebungsraum abgeführt. Das Gas wird hinter der Kühlkammer (12) mit einer Pumpe (16) stetig abgesaugt. überflüssiges Kondenswasser wird ebenfalls mit dieser Pumpe (16) mit abgesaugt. Bei Bedarf wird das der Pumpe (16) entströmende Gas der Kammer oder Rohrleitung mit einer zweiten Verbindung (17) wieder zugeführt.The temperature sensor (9) is surrounded by a fabric stocking (11). This fabric stocking (11) leads through a narrow gap into a lignite chamber (10), which is constantly filled with condensed water. From the measuring chamber (7) the gas is in a cooling chamber (12) in which the existing moisture is condensed as water is precipitated. Via the tap (13) this condensation water becomes the Secondary chamber (10) supplied. The cooling chamber (12) is fitted with a Peltier element (14) chilled. The heat extracted from the gas is transferred to the surrounding area via a heat sink (15) discharged. The gas is continuously sucked off with a pump (16) behind the cooling chamber (12). Superfluous condensed water is also sucked out with this pump (16). If necessary, the gas flowing out of the pump (16) is used in the chamber or pipeline with a second connection (17) fed back.

Die Messung der Feuchtigkeit erfolgt nach dem bekannten psychrometrischen Verfahren mit zwei elektrischen Temperaturfühlern (8) und (9), wobei der Temperaturfühler (8) trocken und der Temperaturfühler (9) ständig befeuchtet ist.The measurement of humidity is carried out according to the well-known psychrometric Method with two electrical temperature sensors (8) and (9), the temperature sensor (8) dry and the temperature sensor (9) is constantly moistened.
