Description
Es sind Gasmeßgerate bekanntgeworden, bei denen durch die Oxydation von Gasen an einem Katalysator eine Wärmetönung hervorgerufen wird und bei denen die Wärmetönung mittels Thermometer oder Differentialtlhernlometer an einer Skala ablesbar gemacht werden soll. Bei diesen bekannten Geräten ist zur Anzeige jedoch eine verhältnismäßig große Erwärmung erforderlich, und dadurch wird die Gefahr von Explosionen herbeigeführt. There are gas meters become known, in which by the oxidation of gases on a catalytic converter cause a catalytic reaction and in which the heat tint using a thermometer or differential thermometer on a scale should be made legible. In these known devices, however, is for display a relatively large amount of heating is required, and this increases the risk of Caused explosions.
Die Erfindung hat ein Gasmeßgerät zum Gegenstand, bei dem schon eine geringe, durch die Oxydation von Gaslbestandteilen an einem Katalysator hervorgerufene Wärmetönung genügt, um die Wärmetõnung und damit die jeweils vorhandene Gasmenge anzuzeigen. Dieses wird dadurch erreicht, daß das Gerät mit einer leicht verdampfbaren Flüssigkeit versehen ist, welche bei Erwärmung eine Quecksilbersäule bewegt, deren Bewegung an einer Skala ablesbar ist. The invention has a gas meter as an object in which already a low levels caused by the oxidation of gas components on a catalyst The heat release is sufficient for the heat release and thus the amount of gas present in each case to display. This is achieved by using the device with an easily vaporizable Liquid is provided, which moves a column of mercury when heated, whose Movement can be read on a scale.
Für die Messung von leichten Gasen wird das eigentliche Meßgerät in eine Diffusionszelle eingebaut, so daß das eingetretene und zu messende Gas gereinigt und frei von Feuchtigkeit, welche die Wandung der Diffusionszelle aufnimmt, an den Katalysator herantritt. Es sind also Feuchtigkeitsbeeinflussungen des Katalysators ausgeschlossen, ebenso Schmutzeinwirkungen. Somit trifft stets ein Gas in gleichmäßigem Zustand den Katalysator, der einen gleichbleibenden Meßvorgang ermöglicht. The actual measuring device is used to measure light gases built into a diffusion cell so that the gas that has entered and is to be measured is cleaned and free of moisture, which the wall of the diffusion cell absorbs, to the Catalyst approaches. So there are moisture influences on the catalyst excluded, as well as the effects of dirt. Thus, a gas always hits in a steady manner Condition of the catalytic converter, which enables a constant measuring process.
Durch das Eintreten des zu messenden Gas-Luft-Gemisches in die Diffusionszelle wird der Katalysator von dem Gas aufgesucltt. Das Gas dringt infolge der Diffusion in den Katalysator ein, erzeugt dort je nach seiner Menge eine entsprechende Wärmetönung, wodurch mittels der leicht verdampfbaren Flüssigkeit eine Quecksilbersäule zum anderen Schenkel einer Ausgleichsröhre hin bewegt wird. When the gas-air mixture to be measured enters the diffusion cell the catalyst is sucked up by the gas. The gas penetrates as a result of diffusion into the catalytic converter, where depending on its quantity, it generates a corresponding heat release, whereby by means of the easily evaporable liquid one column of mercury to the other Leg of a compensation tube is moved out.
An diesem Schenkel der Ausgleichsröhre ist eine Skala angebracht, an der die jeweilige Gasmenge nach Millimetern bestimmt werden kann. Dem Mèßgerät wird eine Tabelle für die verschiedensten Gasarten angefügt, um an Hand der Skala und der Tabelle erkennen zu können, wieviel Volumprozent Gas sich in dem Gas-Luft-Gemisch befindet. A scale is attached to this leg of the compensation tube, on which the respective amount of gas can be determined in millimeters. The measuring device a table for the various types of gas is added to the scale and the table to be able to see how much volume percent gas is in the gas-air mixture is located.
Zur Messung schwerer Gase (Dämpfe) kann das Gerät nicht in einer Diffusionszelle eingebaut werden, weil nunmehr die leichtere Luft innerhalb der Diffusionszelle nach außen dringt, um die Vereinigung mit dem schweren Gas außerhalb der Diffusionszelle zu vollziehen,. Dann wird das Meßgerät also nicht in eine Diffusionszelle eingebaut, sondern in ein gasdichtes Gehäuse. Auch in diesem Falle wird für eine gleichbleibende Anzeige dadurch gesorgt, daß das anzusaugende Gas-Luft-Gemisch eine Entfeuchtungs- und Reinigungskammer durchläuft, in welcher sich Feuchtigkeiten und Schmutz aus den Gasen ansammeln. Das so gereinigte Gas wird durch den Druck eines Gummiballes in das gasdichte Meßgehäuse eingedrückt. Da der Inhalt des Gwmmiballes stets gleichbleibt, wird stets ein Gas-Luft-Gemisch gleicher Menge eingeblasen und dadurch eine Anzeige unter gleichbleibenden Bedingungen gewährleistet. The device cannot be used in a Diffusion cell to be installed because now the lighter air inside the Diffusion cell penetrates to the outside to unite with the heavy gas outside to accomplish the diffusion cell. Then the measuring device does not turn into a diffusion cell built in, but in a gas-tight housing. In this case too, for a constant display ensured that the gas-air mixture to be sucked in a Dehumidification and cleaning chamber runs through, in which humidity and Build up dirt from the gases. The gas cleaned in this way is by the pressure of a Rubber ball pressed into the gas-tight measuring housing. As the content of the Gwmmiballes always remains the same, a gas-air mixture of the same amount is always blown in and this guarantees a display under constant conditions.
In der Zeichnung ist der Erfindergedanke an einem Ausführungsbeispiel erläutert. In Abb. I ist auf einem Grundbiett I die Diffusionszelle 2 mit dem Katalysator 3 dargestellt. Die Diffusionszelle umgibt den linken Schenkel des Ausgleichsrohres 4 mit der Quecksilbersäule 5. Im linken Schenkel befindet sich oberhalb der Quecksilbersäule die leicht verdampfbare Flüssigkeit 6. Am rechten Schenkel des Ausgleichs rohres ist eine Skala 7 mit Angaben der unteren Explosionsigrenze, der toxischen Grenze und der oberen Explosionsgrenze angebracht. Abb. 2 zeigt ein gasdichtes Gehäuse 8 mit dem Katalysator 9, dem AusgleicChsnahr 10 und der Skala II. In the drawing, the inventive concept is based on an exemplary embodiment explained. In Fig. I, the diffusion cell 2 with the catalyst is on a base plate I 3 shown. The diffusion cell surrounds the left leg of the equalizing pipe 4 with the mercury column 5. In the left leg is above the mercury column the easily evaporable liquid 6. On the right leg of the equalizing tube is a scale 7 with details of the lower explosion limit, the toxic limit and the upper explosion limit. Fig. 2 shows a gas-tight housing 8 with the catalyst 9, the balance 10 and the scale II.
Mittels des Gummiballes 12 kann ein Gas-Luft-Gemisch, das durch den Saugstutzen I3 angesaugt wird und die Entfeuchtungs- und Reinigungskammer I4 durchlaufen hat, in das Meßgehäuse eingedrückt werden.By means of the rubber ball 12, a gas-air mixture, which through the Suction nozzle I3 is sucked in and pass through the dehumidifying and cleaning chamber I4 has to be pressed into the measuring housing.
