 EMI1.1 
 



   Es sind Vorrichtungen bekannt, bei denen zum Messen kleiner Druckdifferenzen dat
Steigen einer Flüssigkeitssäule in einem unter beliebiger Neigung angeordneten Glasrobr benutzt wird. Diese Vorrichtungen sind dann nicht anwendbar, sobald die Messung auf einer Unterlage, z. B. auf Fahrzeugen, vorgenommen werden soll, die Schwankungen aus- gesetzt ist. Bei Apparaten für grösseren Messbereich wird selbst durch ihre pendelnde
Aufhängung die zureichende Stabilität der Flüssigkeit nicht erreicht. 



   Gemäss vorliegender Erfindung werden diese Nachteile dadurch vermieden, dass das unter einem der geforderten Empfindlichkeit entsprechenden Winkel ansteigende Messrohr um eine senkrechte Achse gewunden ist,   sowie eine zu Gewindegängen aufgewundene schiefe  
Ebene darstellt. Am unteren Ende eines zylindrischen, senkrechten Glasbehälters a sind zwei
Glasrohre c und d um 1800 versetzt angeschmolzen, die in geringem Abstand vom Behälter au parallelen Gängen aufgewunden sind und offen endigen. Mittels   Anschlussrohr   b wird der Glas- behälter mit demjenigen Raum verbunden dessen   Über. bzw.   Unterdruck gemessen werden   @oll.   



   Zwischen dem Glasbehälter und der Rohrschlange wird eine mit Skala versehene
Trommel angebracht. Die Nullstellung kann, je nach dem Verwendungszweck, durch ver- schiedene Füllung in beliebiger Höhe angebracht werden, so dass man mit dem gleichen
Apparat Über-oder Unterdruck oder beides messen kann. Das Ablesen des Druckes kann von jeder Seite aus erfolgen, die Beobachtung des gauzen Rohres ist sowohl von oben wie auch allseitig möglich. Nötigenfalls wird der Druckmesser zwecks Beibehaltung der senkrechten Stellung mittels der angeschmolzenen Ösen in ein Pendel eingeschaltet.

 EMI1.1
 



   There are known devices in which dat for measuring small pressure differences
Rising a column of liquid in a glass tube arranged at any incline is used. These devices cannot be used as soon as the measurement is carried out on a surface, e.g. B. on vehicles, which is exposed to fluctuations. In the case of devices for a larger measuring range, their pendulum
Suspension does not achieve sufficient stability of the liquid.



   According to the present invention, these disadvantages are avoided in that the measuring tube, which rises at an angle corresponding to the required sensitivity, is wound around a vertical axis, as well as an oblique one wound into threads
Represents level. At the lower end of a cylindrical, vertical glass container a are two
Glass tubes c and d melted, offset by 1800, wound on parallel corridors at a short distance from the container and ending openly. The glass container is connected to the space above by means of a connecting pipe b. or negative pressure can be measured @oll.



   Between the glass container and the pipe coil there is a graduated
Drum attached. The zero position can, depending on the intended use, be attached at any height using different fillings, so that you can use the same
Apparatus can measure positive or negative pressure or both. The pressure can be read from either side, the whole tube can be observed from above as well as from all sides. If necessary, the pressure gauge is switched into a pendulum by means of the fused eyelets in order to maintain the vertical position.
