Während in dem Haupt-Patente No. 52187 entweder eine einfache Röhre oder ein einfacher Stab, von der zu messenden Kraft angegriffen, elastisch in seiner Länge verändert wird und diese Veränderung und damit die Kraft durch eine Flüssigkeit in Verbindung mit einem Mefsrohr in der angegebenen Weise gemessen wird, können auch zwei in einander gesteckte Röhren in folgender Weise zum Messen von Zug- oder Druckkräften angewendet werden.While in the main patent no. 52187 either a simple tube or a simple rod, attacked by the force to be measured, elastic in its length is changed and this change and thus the force through a fluid in connection with a Mefsrohr is measured in the specified way, two can also be in each other Plugged tubes are used in the following way to measure tensile or compressive forces will.
Die Röhre a, Fig. 1, wird von der Röhre b, mit welcher sie am unteren Ende verbunden ist, umschlossen. Die zu messende Kraft drückt auf die obere Fläche der Röhre a, verkürzt letztere und verlängert gleichzeitig die Röhre b. The tube a, Fig. 1, is enclosed by the tube b, to which it is connected at the lower end. The force to be measured presses on the upper surface of the tube a, shortens the latter and at the same time extends the tube b.
Die elastische Längenverä'nderung, welche dabei die beiden Röhren α und b zusammen erleiden, wird dann wieder auf dieselbe Weise wie bei den Apparaten des Haupt-Patentes gemessen, d. h. durch den Stab c, welcher an der unteren Fläche χ des Bodens der Röhre a befestigt ist, wird die Platte d bewegt; diese schliefst mit einer zweiten, an dem oberen Ende der äufseren Röhre durch f befestigten Platte e einen Raum ein, der mit Flüssigkeit gefüllt ist und mit einer Mefsröhre communicirt.The elastic change in length which the two tubes α and b suffer together is then measured again in the same way as with the apparatus of the main patent, ie by the rod c, which is attached to the lower surface χ of the bottom of the tube a is attached, the plate d is moved; This, with a second plate e, fastened to the upper end of the outer tube by f , encloses a space which is filled with liquid and communicates with a measuring tube.
Schliefst man an die Röhre b, Fig. 1 , das Gehäuse g, Fig. 2, an, so kann man, nachdem es durch Ringe, wie Fig. 2 und 3 andeuten, gedichtet ist, die Kraft auch in Form eines Gasoder in Form eines hydraulischen Druckes auftreten lassen, d. h. den Apparat zum Messen von Gas- und Wasserdruck verwenden.If one connects to the tube b , Fig. 1, the housing g, Fig. 2, after it is sealed by rings, as shown in Figs. 2 and 3, the force can also be in the form of a gas or in the form allow hydraulic pressure to occur, ie use the apparatus to measure gas and water pressure.
Bei sehr hohem Druck, z. B. 3000 bis 4000 Atmosphären und mehr, erhält die innere Röhre, Fig. 3, eine oben konische Gestalt, so dafs zwar dieser obere Theil sehr hoch, gegebenenfalls bis oder über seine Elasticitätsgrenze beansprucht wird, nicht aber der zum Messen des Druckes dienende, abwärts von χ liegende Querschnitt k. At very high pressure, e.g. B. 3000 to 4000 atmospheres and more, the inner tube, Fig. 3, has a conical shape at the top, so that this upper part is stressed very high, possibly up to or above its elastic limit, but not the one used to measure the pressure, cross section lying downward from χ k.
Letzterer wird in solchem Falle so grofs gewählt, dafs seine Beanspruchung auch bei dem höchsten Druck, der gemessen werden soll, unter der Elasticitätsgrenze bleibt, mithin die elastische Längenveränderung und damit auch die Stellung der Flüssigkeit in der Mefsröhre bei jedem Druck diesem immer proportional bleibt.In such a case the latter is chosen so large that its stress also increases the highest pressure to be measured remains below the elastic limit, therefore the elastic change in length and thus also the position of the liquid in the Mefs tube with each pressure this always remains proportional.
Aus diesem Grunde ist es möglich, die Mefsröhre für sehr hohe Drucke einzutheilen bezw. diese zu messen.For this reason it is possible to subdivide the Mefsröhre for very high pressures respectively. measure this.
