PATENTAMT.PATENT OFFICE.
Die Meßgenauigkeit von Instrumenten, die starken Erschütterungen, beispielsweise auf Fahrzeugen, ausgesetzt sind, leidet bekanntlich stark unter den Stößen, besonders bei solchen Instrumenten, deren messende Systeme infolge ihrer federnden Eigenschaften in Schwingungen geraten können. Insbesondere sind Meßgeräte mit mehreren hintereinander geschalteten Meßdosen, ζ. Β. Staudruckgeschwindigkeitsmesser,The measurement accuracy of instruments that are subject to strong vibrations, for example Vehicles that are exposed are known to suffer greatly from the impacts, especially when they are Instruments whose measuring systems vibrate due to their resilient properties can guess. In particular, measuring devices with several load cells connected in series, ζ. Β. Dynamic pressure speedometer,
ίο gegen Stöße empfindlich.ίο sensitive to shocks.
Bei derartigen Apparaten, bei welchen mehrere Meiödosen aus verhältnißmäßig schwachem Material hintereinander geschaltet sind, werden erfindungsgemäß die bei Stößen auftretenden Mängel dadurch verhindert, daß im Innern der Meßdosen Führungsröhren angeordnet sind, die in den Zuführungsteilen fest gelagert und mit Öffnungen versehen sind, welche in die einzelnen Meßdosen münden, um eine gleichmäßige Druckverteilung in dem gesamten Meßsystem zu erzielen.In such apparatus, in which several meiedoses from a comparatively weak one Material are connected in series, according to the invention are those that occur in the event of impacts Defects prevented by the fact that guide tubes are arranged inside the load cells that are firmly mounted in the feeder parts and provided with openings, which open into the individual load cells to ensure an even pressure distribution in the to achieve the entire measuring system.
Eine Ausführungsform des Gegenstandes istOne embodiment of the subject matter is
beispielsweise aus der Zeichnung zu ersehen.for example to see from the drawing.
Die Ausführungsform stellt zwei Systeme von hintereinander geschalteten Dosen 1 dar, wie sie beispielsweise für die genannten Staudruckgeschwindigkeitsmesser Verwendung finden. Die Beweguug der Kapseln wird bei dieser Anordnung durch die Parallelogrammführung 2, 3, 4 auf ein nicht gezeichnetes Zeigerwerk in an sich bekannter Weise übertragen. Durch die Mittelöffnungen der einzelnen Dosen ragen Führungsröhren 5 und 6 hindurch, welche mit Löchern versehen sind, so daß die Luft gleichmäßig in jede der Dosen gepreßt bzw. aus ihnen abgesaugt werden kann, und die in den Zuführungsteilen 7 und 8 fest gelagert sind.The embodiment represents two systems of cans 1 connected in series, as they are used, for example, for the aforementioned dynamic pressure sensors. With this arrangement, the movement of the capsules is controlled by the parallelogram guide 2, 3, 4 transferred in a manner known per se to a pointer mechanism (not shown). Guide tubes 5 and 6 protrude through the central openings of the individual cans, which are provided with holes so that the air is pressed evenly into each of the cans or can be sucked out of them, and which are fixedly mounted in the feed parts 7 and 8 are.
Der Erfindungsgegenstand ist allgemein anwendbar für Meßgeräte, bei denen mehrere hintereinander geschaltete Meßdosen Verwendung finden, also bei allen barometrischen oder manometrischen Instrumenten usw. Durch die Einrichtung wird vermieden, daß etwa die mittleren Dosen bei seitlich auftretenden Stößen ausweichen können und dadurch Meßfehler hervorrufen.The subject matter of the invention is generally applicable to measuring devices in which several series-connected load cells are used, that is, with all barometric or manometric instruments, etc. The facility avoids having about the medium doses can evade side impacts and thus measurement errors cause.
