Description

"Absortionsmeßerät" Die Erfindung bezieht sich auf ein Absorptionsmeßgerät, bestehend aus einer Kammer, in die ein Probenmedium, insbesondere ein Probengas, gegeben werden kann, einer Quelle, mit der ein Strahl, insbesondere ein Infrarotlichtstrahl, durch die Kammer geschickt werden kann, und einem Detektor, der den Strahl auffängt. "Absortionsmeßerät" The invention relates to an absorption meter, consisting of a chamber into which a sample medium, in particular a sample gas, can be given, a source with which a beam, in particular an infrared light beam, by the chamber can be sent, and a detector that catches the beam.

Bei bekannten Geräten dieser Art wird das Probengas mittels einer Pumpe in die Kammer gefördert.In known devices of this type, the sample gas is by means of a Pump delivered into the chamber.

Der Erfindung liegt die Aufgabe zugrunde, dieses Gerät zu vereinfachen.The invention is based on the object of simplifying this device.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Wand der Kammer- ganz oder teilweise porös ist.This object is achieved in that the wall of the Chamber is completely or partially porous.

Auf diese Weise wird erreicht, daß die Pumpe und die Zuleitungen entfallen können. Das Probenmedium dringt im Wege der Diffusion durch die porösen Wände in die -Kammer ein. Das erfindungsgemäße Gerät kann zum Beispiel als tragbares Gerät oder als Gerät mit Feriniießkopf, der z. B. sich in großer Entfernung vom Speise- und Anzeigeteil befindet und mit diesem über Kabel verbunden ist, ausgebildet sein.In this way it is achieved that the pump and the supply lines are omitted can. The sample medium penetrates by diffusion through the porous walls the chamber. The device according to the invention can for example be used as a portable device or as a device with Feriniießkopf, the z. B. at a great distance from the food and display part is located and is connected to this via cables.

In den Figuren 1 und 2 der Zeichnung sind zwei Ausführungsbeiapiele der Erfindung dargestellt.In Figures 1 and 2 of the drawing are two exemplary embodiments of the invention shown.

In beiden Fällen ist mit 1 eine Kammer, mit 2 ein Strahler und mit 3 ein Detektor bezeichnet. Die Wände der Kammer 1 sind porös. Im Falle der Figur 2 ist die Wand 4 verspiegelt. Die Ausführungsform gemäß Figur 2 stellt eine besonders kompakte Lösung dar.In both cases 1 is a chamber, 2 is a radiator and with 3 denotes a detector. The walls of the chamber 1 are porous. In the case of the figure 2, the wall 4 is mirrored. The embodiment according to FIG. 2 represents a special one compact solution.
