PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine weitere Ausbildung des hydrostatischen Differentialmanometers kombiniert mit Manometer nach Patent 243250. Dort ist eine Kombination beschrieben, bei der das den Schwimmer des Manometers aufnehmende Rohr gegen den Meßdruck abgeschlossen, gegen die Atmosphäre offen ist.The invention relates to a further embodiment of the hydrostatic differential manometer combined with manometer according to patent 243250. There a combination is described in which the float of the Manometer receiving tube closed against the measuring pressure, against the atmosphere is open.
Die Einrichtung kann auch so getroffen werden, daß das den Schwimmer des Manometers aufnehmende Rohr i gegen den Meßdruck offen, gegen die Atmosphäre abgeschlossen ist. Bei dieser in der Zeichnung dargestellten Anordnung ist der Registrierraum gegen die Atmosphäre dicht abgeschlossen; der eine der Drucke, deren Differenz gemessen werden soll, wird durch e in den Raum A, der andere durch f in den Raum B geleitet. Rohr i ist hier nach dem einen Meßdruck hin offen und taucht unten in die Flüssigkeit II des nach B hin vollständig geschlossenen Rohres b. Rohr b steht durch m mit der Atmosphäre in Verbindung. Die Bewegung des Flüssigkeitsspiegels in b und i und damit der Hub des Schwimmers s erfolgt proportional dem Druckunterschied zwischen B und der Atmosphäre. Die Bewegung des Schwimmers s wird mittels Schreibstange g auf die Diagrammtrommel ft übertragen, während auf die gleiche Trommel die der Druckdifferenz proportionale Bewegung der in die Flüssigkeit I eintauchenden Druckglocke d mittels Schreibstange K übertragen wird.The device can also be made so that the tube i holding the float of the manometer is open against the measuring pressure and closed against the atmosphere. In this arrangement shown in the drawing, the registration space is sealed off from the atmosphere; One of the pressures, the difference of which is to be measured, is passed through e into room A, the other through f into room B. I pipe is open here after a measurement pressure and dips down into the liquid II of the down completely closed after the tube B b. Tube b communicates with the atmosphere through m. The movement of the liquid level in b and i and thus the stroke of the float s is proportional to the pressure difference between B and the atmosphere. The movement of the float s is transmitted to the diagram drum ft by means of the writing rod g, while the movement of the pressure bell d immersed in the liquid I, which is proportional to the pressure difference, is transmitted to the same drum by means of the writing rod K.
Der Schwimmer s kann auch statt in Rohr i in den Ringraum zwischen i und b eingebaut werden, da dieser Flüssigkeitsspiegel in gleicher Weise wie der in i durch den Druckunterschied beeinflußt wird.The float s can also be installed in the annular space between i and b instead of in pipe i , since this liquid level is influenced by the pressure difference in the same way as that in i.
Natürlich kann auch hier ein Differentialmanometer beliebiger Konstruktion Verwendung finden und Druck und Differenzdruck statt auf die gleiche Trommel auf zwei verschiedene Trommeln aufgezeichnet werden.Of course, a differential manometer of any design can also be used here find and pressure and differential pressure instead of on the same drum on two different ones Drums are recorded.
