Während beim bekannten Luftthermometer der Druck, welchen das im Luftgefäfs bei constantem Volumen erhitzte Gas ausübt, gemessen und die Temperatur desselben dann berechnet wird, gestattet das den Gegenstand dieser Erfindung bildende Luftthermometer, die Volumenänderung des Gases bei angenähert constantem Druck und somit die Temperatur unmittelbar zu messen.While with the known air thermometer the pressure, which that in the air vessel at constant Volume heated gas exerts, measured and the temperature of the same then calculated the air thermometer object of this invention allows the volume change of the gas at approximately constant pressure and thus the temperature can be measured directly.
Das Luftgefäfs L steht durch eine Röhre R mit einem Gefäfs A in Verbindung. In letzterem befindet sich Quecksilber, in welches eine Röhre B, die oben mit einer Erweiterung W versehen ist, eingetaucht ist. An diese schliefst sich die mit Scala versehene, möglich waagrecht gestellte Röhre M. Die Röhre B und ein Theil der Erweiterung W sind mit Quecksilber, der Rest der Erweiterung mit Alkohol gefüllt. Der zwischen Luftgefäfs und Mefsröhre sich befindende Theil des Thermometers ist das Neue an demselben.The air vessel L communicates with a vessel A through a tube R. In the latter there is mercury, into which a tube B, which is provided with an extension W at the top, is immersed. The tube M , provided with a scale and possibly placed horizontally, is attached to this. Tube B and part of the extension W are filled with mercury, the rest of the extension with alcohol. The part of the thermometer between the air vessel and the measuring tube is what is new about it.
Statt Quecksilber und Alkohol können auch andere Flüssigkeiten genommen werden, auch kann statt der Erweiterung W ein Gefäfs zwischen B und M eingeschaltet werden.Instead of mercury and alcohol, other liquids can also be used, and instead of the extension W, a vessel between B and M can be inserted.
Durch das im Luftgefäfs erhitzte Gas wird nun der Alkohol in die Mefsröhre M getrieben, ohne dafs die Länge der dazwischen sich befindlichen Quecksilbersäule und somit der auf dem Gase liegende Druck wesentlich geändert wird.By the gas heated in the air vessel, the alcohol is now driven into the measuring tube M without the length of the mercury column located in between and thus the pressure on the gas being significantly changed.
