   Da es bei solchen Messungen darauf ankommt, dass das Messgerät einen möglichst kleinen Widerstand leistet, so gestaltet man den Hohlkörper 1 derart, dass eine seiner Wände möglichst leicht nachgibt
Fig. 5 stellt eine derartige Ausführungsform dar.

 man die Schraube 5, so zeigt die Steighöhe der Flüssigkeit im Röhrchen 3 die Änderung des Abstandes der Schraubenspitze von der Spitze des Stiftes 6 an. Der Hohlraum in der Kammer 2 mit Röhrchen 4 dient wieder zur   Unschädlichmachung   von Temperaturschwankungen. 



   Statt eines Glasrohres mit Teilung kann man sich auch anderer Mittel zur Messung der Volumenveränderung bedienen. Beispielsweise lässt man eine   Feinmessschraube   in den zu messenden Hohlraum tauchen und dreht die Schraube so, dass die Flüssigkeitssäule stets auf dieselbe Marke einspielt.

   Since it is important in such measurements that the measuring device offers the lowest possible resistance, the hollow body 1 is designed in such a way that one of its walls yields as easily as possible
Fig. 5 illustrates such an embodiment.
 EMI2.1
 If the screw 5 is used, the height of rise of the liquid in the tube 3 shows the change in the distance between the screw tip and the tip of the pin 6. The cavity in the chamber 2 with the tube 4 is again used to render temperature fluctuations harmless.



   Instead of a glass tube with a graduation, other means of measuring the change in volume can also be used. For example, you can dip a micrometer into the cavity to be measured and turn the screw so that the column of liquid always points to the same mark.

Claims

PATENT CLAIM: Measuring devices for force effects resp. to determine small changes in size, ge. characterized by an elastic body which contains two cavities of the same size, lying next to one another or enclosing one another, filled with an equal amount of the same liquid, which are arranged in such a way that one of the two cavities undergoes an elastic change in size due to the force to be measured, which at one is measured with the reading device in connection with the cavity, while the second cavity does not undergo any change in size due to the force to be measured or a change in size in a different ratio than the first cavity and for determination or

The purpose of eliminating temperature fluctuations occurring during the measurement is.
