Vorrichtung zur Bestimmung von brennbaren Bestandteilen in Gasen.
Es ist bekannt, zur Bestimmung des Gehaltes an brennbaren Gasen das zu untersuchende Gasgemisch an einem elektrisch geheizten Metalldraht vorbeistreichen zu lassen. Die Temperatur des Drahtes
EMI1.1
der ziemlich hohen Temperatur, auf die er erhitzt wird, leicht reisst.
Gemäss der Erfindung wird der Draht daher zu einer Schraube aufgewickelt, die so fe'n ist, dass der schraubendurchmesserin der Grössenordnung des Durchmessers des Drahtesselbst liegt, also nicht grösser ist als etwa das Vierfache des Drahtdurchmessers. Eine derartige Schraube strahlt, wie die Technik
EMI1.2
der Schraube sich gegenseitig heizen. Man kommt daher mit geringerer Energie aus, oder man kann, und darin liegt der Hauptvorteil, ohne die elektrische Energie erhöhen zu müssen, den Durchmesser des Drahtes vergrössern. Die so erzielte Durchmesservergrösserung genügt, um dem Draht die Lebensdauer zu geben, die ihn erst praktisch verwertbar macht.
Ausserdem hat die Schraube aus dem stärkeren Draht eine erhebliche elastische Dehnung und ermöglicht seine Ausspannung in der Messkammer unter so grossem Zuge, dass die Achse der Schraube stets gradlinig bleibt.

Device for determining combustible components in gases.
It is known to allow the gas mixture to be examined to sweep past an electrically heated metal wire in order to determine the content of combustible gases. The temperature of the wire
EMI1.1
the rather high temperature to which it is heated.
According to the invention, the wire is therefore wound into a screw which is so fine that the screw diameter is of the order of magnitude of the diameter of the wire itself, i.e. not greater than approximately four times the wire diameter. Such a screw shines like the technology
EMI1.2
the screw heat each other. You can get by with less energy, or you can, and this is the main advantage, without having to increase the electrical energy, to increase the diameter of the wire. The increase in diameter achieved in this way is sufficient to give the wire the service life that makes it usable in practice.
In addition, the screw made from the thicker wire has a considerable elastic expansion and enables it to be unclamped in the measuring chamber with such a great pull that the axis of the screw always remains straight.
