Description

Vorrichtung zur Feststellung des Feuchtigkeitsgehalts der Luft. Die Vorrichtung besteht aus einer Säule, die aus einzelnen Plättchen von Holz oder einem ähnlichen, wasserempfindlichen Material zusammengesetzt ist. Auf der beiliegenden Zeichnung befindet sich die Vorrichtung in einer Rohrleitung e, welche an einen Apparat zur Herstellung von Sauerstoff angeschlossen ist.Device for determining the moisture content of the air. the Device consists of a column made up of individual platelets of wood or a similar, water-sensitive material is composed. On the enclosed Drawing is the device in a pipe e, which is connected to a Apparatus for the production of oxygen is connected.

Durch eine Zugstange b und mittels der starken Feder c «-erden die Plättchen a dicht aufeinandergepreßt. Diese Pressung wird im vorliegenden Falle noch erhöht durch den in der Rohrleitung e befindlichen Überdruck, der bei Sauerstoffapparaten et-%va 35 Atm. beträgt.The Plate a tightly pressed together. This pressing is in the present case further increased by the overpressure in the pipe e, which is the case with oxygen apparatus et% above 35 atm. amounts to.

DieStopfbüchse f soll zwecks besserenGleitens Grafiteinlage erhalten.The stuffing box f should have a graphite insert for better sliding.

Das Zifferblatt d ist an einer Rohrkappe gegen Vershieben festgehalten. Die Zugstange b ist am äußeren linde gezahnt und nimmt den Zeiger beim Schwinden oder Ouellen der wasserempfindlichen Masse mit. Die wasserempfindlichen Plättchen sind in der Zugstangenrichtung durchbohrt, um der Luft eine größere Fläche zu bieten.The dial d is held on a tube cap to prevent it from being chipped. The pull rod b is toothed on the outer linden tree and takes the pointer when it disappears or source the water-sensitive mass with. The water-sensitive platelets are pierced in the tie rod direction to provide a larger area for air.
