Description

Gegenstand älterer Erfindungen ist es, Stoff-, insbesondere Gasgemische, von denen z. B. eine Komponente eine von der der übrigen abweichende Suszeptibilität besitzt, dadurch zu analysieren, daß man sie einem inhomogenen Magnetfeld aussetzt ihre Dichte z. B. durch Temperaturerhöhung an einer Steile des inhomogenen Feldes ändert und die dabei auftretende Strömung mißt. The subject of older inventions is to identify substance, in particular gas mixtures, of which z. B. one component has a different susceptibility than the rest has to analyze by exposing them to an inhomogeneous magnetic field their density z. B. by increasing the temperature on a part of the inhomogeneous field changes and measures the flow occurring in the process.

Gegenstand der Erfindung ist es, die Meßzelle als vom dem übrigen Gerät getrennte Sonde auszuführen. Der Vorteil dieser Anordnung liegt darin, daß das zu untersuchende Gasgemisch nicht in das Meßgerät eingeführt zu werden braucht, sondern die Meßsonde in das zu untersuchende Gasgemisch gebracht werden kann. Das ist insbesondere dann von Vorteil, wenn die Entnahme von Gasproben nicht möglich ist oder wenn mit dem gleichen Gerät schnell nächeinander verschiedene Gasgemische analysiert werden sollen. Zu dem Zweck kann man sich auch mit Vorteil mehrerer Meßsonden bedienen, die an das gleiche Ablesegerät entweder nacheinander oder aber z. B. zur Messung von Konzentrationsdifferenzen gleich7eitig geschaltet sind. The object of the invention is the measuring cell as from the rest Device to run a separate probe. The advantage of this arrangement is that the gas mixture to be examined does not need to be introduced into the measuring device, but the measuring probe can be brought into the gas mixture to be examined. That is particularly advantageous when it is not possible to take gas samples or when different gas mixtures are used in quick succession with the same device should be analyzed. For this purpose one can also take advantage of several measuring probes operate that to the same reader either one after the other or z. B. to Measurement of concentration differences are switched at the same time.

Die Abt 1 und 2 zeigen schematisch ein Ausführungsbeispiel der Sonde nach der Erfindung, und zwar Abb. I in Seiten- und Abb. 2 in Draufsicht. The abbots 1 and 2 show schematically an embodiment of the probe according to the invention, namely Fig. I in side and Fig. 2 in plan view.

Im Innern eines Topfmagneben X befinden sich, an Eisenplatten 2 befestigt, die Polschuhe 3 und 4. Inside a pot magnet next to X are, attached to iron plates 2, pole pieces 3 and 4.

Im inhomogenen Teil des zwischen den Magnetpolen herrschenden Feldes ist ein Heizdraht 5 angeordnet, in einer Bohrung 7 des Polschuhes 3 der Heizdraht 6. Der an dem die elektrischen Zuleitungen tragenden Haltestab 8 befestigte Topfmagnet 1 ist mit Löchern 9 versehen, durch die das zu untersuchende Gasgemisch in die Mel.S-kammer lo tritt. Die Heizdrähte 5 und 6 sind z. B. in einer elektrischen, in den Abbildungen nicht besonders dargestellten Brücke derart geschaltet, daß sich eine zwischen ihnen- auftretende Temperaturdifferenz messen läßt. Wird die gemäß Abb. 1 und 2 ausgebildete Meßsonde in ein Gasgemisch gebracht, von dem z. B. eine zu messende Komponente eine vom Wert Null abweichende Suszeptibilität besitzt, so entsteht infolge der am Draht 5 auftretenden Strömung zwischen den Drähten 5 und 6 eine Temperaturdifferenz, deren Größe ein Maß für den Gehalt des Gasgemisches an der zu messenden Komponente ist.In the inhomogeneous part of the field between the magnetic poles a heating wire 5 is arranged in a bore 7 of the pole piece 3 of the heating wire 6. The pot magnet attached to the holding rod 8 carrying the electrical leads 1 is provided with holes 9 through which the gas mixture to be examined enters the Mel.S chamber lo kicks. The heating wires 5 and 6 are z. B. in an electrical, in the pictures not specifically shown bridge connected in such a way that a between them- can measure the temperature difference that occurs. Is the one trained according to Fig. 1 and 2 Measuring probe brought into a gas mixture from which z. B. a component to be measured a If the susceptibility deviates from the value zero, then it arises as a result of the on the wire 5 occurring flow between the wires 5 and 6 a temperature difference, whose Size is a measure of the content of the gas mixture in the component to be measured.

Zweckmäßig ist es, die Heizdrahte 5 und 6 räumlich dicht benachbart anzuordnen, damit Schwankungen der Temperatur der Meßsonde auf beide Drähte gleichzeitig einwirken und infolgedessen auf die Messung der Temperaturdifferenz beider Drähte keinen Einfluß ausüben. It is useful to spatially closely adjoin the heating wires 5 and 6 to arrange so that fluctuations in the temperature of the measuring probe on both wires at the same time act and consequently on the measurement of the temperature difference between the two wires exert no influence.
