Description

Aus einem Metallrohr mit isoliert eingesetzten Kontaktstiften bestehende Kontaktsäule für Meßvorrichtungen mit elektrischer Anzeige oder Messung, insbesondere für Differentialmanometer. Die Anordnung einer großen Zahl einander nahe liegender Kontaktstifte in einem Metallkörper verursacht gewisse Schwierigkeiten in der Abdichtung, die im Hauptpatent durch eigenartige Gestaltung der Kontaktstifte beseitigt werden. Die Erfindung gibt eine weitere Lösung für die Aufgabe der dichten Lagerung der Kontaktstifte, die auch in Verbindung mit der Lösung nach dem Hauptpatent Anwendung finden kann. Diese Lösung besteht darin, daß die Kontaktstifte auch auf der Außenseite unter den an ihren inneren Enden herrschenden Flüssigkeits- oder Gasdruck versetzt werden. Ihre äußeren Enden und die an diese anschließenden Widerstände werden zu diesem Zwecke in einer Kammer eingeschlossen, die mit derselben Druckleitung in Verbindung steht wie der Raum, in dem die inneren Kontaktenden münden.Consists of a metal tube with insulated inserted contact pins Contact column for measuring devices with electrical display or measurement, in particular for differential manometer. The arrangement of a large number closer together Contact pins in a metal body cause certain difficulties in sealing, which are eliminated in the main patent by the peculiar design of the contact pins. The invention gives a further solution to the problem of the tight storage of the Contact pins, which are also used in connection with the solution according to the main patent application Can be found. This solution is that the contact pins are also on the outside displaced under the liquid or gas pressure prevailing at their inner ends will. Their outer ends and the resistors connected to them become too for this purpose enclosed in a chamber connected to the same pressure line in Connection is like the space in which the inner contact ends flow.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel. In der Kontaktsäule b sind die Kontaktstifte g angeordnet. Die an den äußeren Enden der Kontaktstifte angeschlossenen Widerstände h liegen in einer Kammer i, die in dem dargestellten Ausführungsbeispiel durch eine auf der Kontaktsäule b dicht aufgeschraubte Kappe gebildet wird und durch eine Bohrung h mit der Gas- oder Dampfzuleitung zur Kontaktsäule in Verbindung steht.The drawing illustrates an embodiment. The contact pins g are arranged in the contact column b. The resistors h connected to the outer ends of the contact pins are located in a chamber i, which in the illustrated embodiment is formed by a cap screwed tightly onto the contact column b and is connected to the gas or steam feed line to the contact column through a bore h.

Die Kammer i ist zweckmäßig mit einer isolierenden Flüssigkeit, beispielsweise Öl, gefüllt, ähnlich wie die Kontaktsäule eine isolierende Flüssigkeit enthält. Dadurch wird verhindert, daß der Dampf zu den Widerständen gelangt, so daß diese keinen Temperaturschwankungen unterworfen sind, welche die Genauigkeit der Anzeige nennenswert beeinflussen können.The chamber i is conveniently filled with an insulating liquid, for example Oil, filled, similar to how the contact column contains an insulating liquid. This prevents the steam from reaching the resistors, so that these are not subject to temperature fluctuations, which would affect the accuracy of the display can influence significantly.
