Description

Thermoelement aus Kohle und Siliciumcarbid Die Erfindung betrifft ein Thermoelement aus Kohle und Siliciumcarbid. Bislang wurden die Thermoelemente dieser Art in der Weise ausgeführt, daß die beiden Thermoelesnentkomponenten jeweils für sich aus einem Stück bestanden. Nun ist aber die Kontaktstelle eines Thermoelementes in besonders starrem Maße der zerstörenden Einwirkung des hocherhitzten M.eßgutes ausgesetzt, so daß bei den bisher bekannten Thermoelementen bei einer -Zerstörung des unteren Teils das ganze Thermoelement unbrauchbar wurde. AuSerdem ist auch, wenn d.e Thermoelemente eine gewisse Länge besitzen müssen, die Herstellung sehr teuer.Carbon and Silicon Carbide Thermocouple This invention relates to a thermocouple made from carbon and silicon carbide. So far the thermocouples were executed this way in such a way that the two thermal element components respectively consisted of a single piece. But now it is the contact point of a thermocouple in a particularly rigid measure of the destructive effect of the highly heated meat exposed, so that with the previously known thermocouples with a destruction of the lower part the whole thermocouple became unusable. In addition, it is also if the thermocouples have to have a certain length, the production very much expensive.

Die Erfindung schlägt nun vor, daß die beiden Komponenten eines Thermoelementes aus Kohle und Siliciumcarbid, von denen in bekannter Weise die eine als Stab und die andere als ein diesen Stab umschließendes Rohr ausgebildet sind, aus einzelnen Tei en aufzubauen und diese Einzelteile miteinander zu verschrauben. Es kann also, wenn bei einem derartig aufgebauten Thermoelement einer der Teile schadhaft geworden ist, dieser Teil ausgewechselt werden. Es braucht also nicht ein vollkommen neues Ther.noelement eingebaut zu werden. The invention now proposes that the two components of a thermocouple of carbon and silicon carbide, one of which is known as a rod and the others are designed as a tube enclosing this rod, from individual Build up parts and screw these individual parts together. So it can if one of the parts of a thermocouple constructed in this way has become defective is this part to be replaced. So it doesn't need a completely new one Ther.noelement to be built in.

In der Abbildung ist ein Thermoelement gemäß der Erfindung dargestellt. Es besteht aus drei miteinander verschraubten Teilstücken A/B, C/D und Elf. B ist der stabförmige Teil des Kontakt eits, der in den rohrförmigen Teil A eingeschraubt ist. An dem rohrförmigen Teil A wird an dem o e--en Ende der rohrförmige Teil D eingeschraubt. Zur Abstandhaltung zwischen dem stabförmigen Teil und dem rohrförmigen Teil sind Isolierstücke 1 vorgesehen. Auf den Teil C D fo'gt in der gleichen Weise ein weiterer E/F usf. The figure shows a thermocouple according to the invention. It consists of three parts A / B, C / D and Elf screwed together. Are you the rod-shaped part of the contact which is screwed into the tubular part A. is. On the tubular part A, the tubular part D is at the open end screwed in. To keep the distance between the rod-shaped part and the tubular part Part insulating pieces 1 are provided. Part C D follows in the same way another E / F etc.
