 EMI2.1 
 Rohrwand A gebildet werden. Bei Verwendung von Röhrchen als   Füllkörper   werden diese   zweckmässig-   auf einem Kreise oder in mehreren gleichachsigen Reihen um das Rohr S herum angeordnet. Der Baustoff für die Füllkörper weist eine so hohe Wärmeleitzahl auf, dass im Zusammenhang mit der beschriebenen Anordnung der Wärmeaustausch von oder zu dem Thermoelement verhindert und die konvektive Übertragtmg der Gastemperatur auf die Lötstelle L wesentlich gefördert wird. Anstatt des Thermoelementes   kann   auch je nach den Betriebsverhältnissen ein anderes Temperaturmessgerät, wie z. B. ein Widerstandsthermometer verwendet werden. 



   PATENT-ANSPRÜCHE :
1. Absaugepyrometer, dadurch gekennzeichnet, dass die Lötstelle des Thermoelementes bzw. das Ende des Thermometerschutzrohres von Einlagekörpern umgeben ist, welche dem Gas eine grosse Heizfläche darbieten und hohe Wärmeübergangszahlen aufweisen, so dass das Thermometer infolge Ausschaltung des Strahlungseinflusses der Umgebung die wahre Temperatur des vorbeiströmenden Gases annimmt.

 EMI2.1
 Pipe wall A are formed. When using tubes as filling bodies, these are expediently arranged around the tube S in a circle or in several equiaxed rows. The building material for the packing has such a high coefficient of thermal conductivity that, in connection with the arrangement described, the heat exchange from or to the thermocouple is prevented and the convective transfer of the gas temperature to the soldering point L is significantly promoted. Instead of the thermocouple, depending on the operating conditions, another temperature measuring device, e.g. B. a resistance thermometer can be used.



   PATENT CLAIMS:
1. Suction pyrometer, characterized in that the soldering point of the thermocouple or the end of the thermometer protection tube is surrounded by insert bodies, which offer the gas a large heating surface and have high heat transfer coefficients, so that the thermometer, due to the elimination of the radiation influence of the environment, the true temperature of the flowing past Gas.

Claims (1)

2. Pyrometer nach Anspruch 1, dadurch gekennzeichnet, dass als Einlagekörper Röhrchen oder Stäbchen verwendet werden. 2. Pyrometer according to claim 1, characterized in that tubes or rods are used as the insert body. 3. Pyrometer nach Anspruch 1, dadurch gekennzeichnet, dass die Einlagekörper mit der äusseren Rohrwand oder mit dem Thermometerschutzrohr bzw. mit beiden zusammen ein Stück bilden. 3. Pyrometer according to claim 1, characterized in that the insert body with the outer tube wall or with the thermometer protection tube or with both together form a piece. 4. Pyrometer nach Anspruch 3, dadurch gekennzeichnet, dass die Einlagekörper dureh Verbindungs- rippen zwischen Thermometerschi tzrohr und äusserer Rohrwand gebildet werden. EMI2.2 4. Pyrometer according to claim 3, characterized in that the insert bodies are formed by connecting ribs between the thermometer tube and the outer tube wall. EMI2.2
