Description

Die vorliegende Erfindung bezieht sich auf eine besondere Ausgestaltung des Gasanzeigegerätes, insbesondere Schlagwetteranzeigers, mit Temperaturausgleich nach Patent 869 428. The present invention relates to a particular embodiment of the gas indicator, in particular the firedamp indicator, with temperature compensation according to patent 869,428.

Gemäß der vorliegenden Erfindung bestehen die beiden gleichen, auf Wärme ansprechenden Systeme aus Thermobimetallstreifen an Stelle von zwei Röhrchen, welche mit wärmeempfindlichen Mitteln gefüllt sind. Es wird daher auf Grund der vorliegenden Erfindung eine wesentliche Vereinfachung des Anzeigegerätes erzielt. According to the present invention, the two consist of the same Heat-sensitive systems made of thermal bimetallic strips instead of two tubes, which are filled with heat-sensitive agents. It is therefore due to the present invention achieved a substantial simplification of the display device.

Die Zeichnung zeigt ein Ausführungsbeispiel des Gerätes nach der Erfindung. Wie ersichtlich, sind die beiden Thermobimetallstäbe I und 2 an dem .Gehäuse 3 befestigt. Der Stab I trägt den Katalystator 4, während der Stab 2 die dem Katalysator ähnlich geformte Hülle 5 trägt, die den gleichen Wärmedurchgangswert wie der Katalysator 4, aber keine aktive Masse besitzt. Liest verbunden mit dem Thermobimetallstab 2 ist die Skala 6, während der Zeiger 7 fest auf dem Stab I angeordnet ist. The drawing shows an embodiment of the device according to Invention. As can be seen, the two thermal bimetallic bars I and 2 are on the housing 3 attached. The rod I carries the catalyst 4, while the rod 2 carries the catalyst similarly shaped shell 5 carries the same heat transmission value as the catalyst 4, but has no active mass. Reads connected to the bimetal thermo stick 2 is the scale 6, while the pointer 7 is fixed on the stick I.

Bei einer Temperaturerhöhung des gesamten Systems biegen sich beide Thermobimetallstäbe gleichmäßig durch. Skala 6 und Zeiger 7 machen diese Bewegung mit, so daß die Nullstellung des Zeigers erhalten bleibt. Erfährt aber der Thermobimetallstab I durch den Katalysator 4 eine zusätzliche Temperaturerhöhung, so tritt eine stärkere Durchbiegung ein, die an der Skala 6 abgelesen werden kann. Da die im Katalysator 4 entstehende Temperatur abhängig ist von dem Prozentsatz des Gases im Gasluftgemisch, läßt sich die Skala 6 in Prozenten eichen Auf der wieder mit dem Gehäuse fest verbundenen Skala 8 läßt sich die Bewegung des (Bimetallstabes 2 ablesen, die abhängig von der Temperatur des gesamten Systems ist und damit auch die Temperatur des gesamten Systems anzeigt. When the temperature of the entire system rises, both bend Thermobimetal rods evenly through. Scale 6 and pointer 7 make this movement with so that the zero position of the pointer is retained. But the thermo-bimetallic rod learns If there is an additional temperature increase due to the catalytic converter 4, then a stronger one occurs Deflection, which can be read on the scale 6. Because the one in the catalytic converter 4 the resulting temperature depends on the percentage of gas in the gas-air mixture, the scale 6 can be calibrated in percent on the firmly connected to the housing again Scale 8 shows the movement of the (bimetallic rod 2, which depends on the Is the temperature of the entire system and therefore also the temperature of the entire system indicates.
