スがあることを４虞に入れなければ収らない。An infrared emitter of the type mentioned above is disclosed in U.S. Pat. No. 3,614.
It is known from specification No. 387. In this known infrared radiator, an electric heating coil is embedded in an electrically insulating material, for example of magnesium oxide or boron nitride, in a metal jacket tube. The metal jacket tube is closed at both ends with plugs. In order to measure the temperature of the jacket tube, a thermoelement is provided as a temperature sensor on its inner surface. In such a configuration, sensing the temperature of the heating coil involves a considerable time delay;
Therefore, it is necessary to take into account the fact that there is a considerably large hysteresis in constant temperature control.

出力制御を最適化することができる。The above-mentioned problem is solved in the type of infrared emitting device or radiator mentioned at the beginning, in which a heating coil is mounted in a carrier tube made of a workpiece material containing silicon dioxide and arranged with play inside the tube. The solution lies in arranging a temperature sensor inside the carrier tube. Advantageously, the carrier tube is formed from a quartz material or quartz glass that is transparent to infrared radiation. 5. Working of the outer tube (I include quartz material, quartz glass or high silica glass. The carrier tube is arranged so as to penetrate the wall of the outer tube in the end region of the outer tube. Advantageously, the temperature sensor is arranged displaceably inside the jacket tube, so that during operation of the infrared radiator, different heating coils can be used by displacing the temperature sensor inside the carrying tube. The temperature of the area can be detected. Temperature sensors include thermoelements, but it is also possible to arrange other temperature sensors inside the carrier tube. The carrier tube itself has a Advantageously, it is designed as a capillary tube with an internal diameter in the region of 2s+a, the wall thickness of which is in the range 0.5 to 2m11. The arrangement inside the carrier tube for the heating coil, which is made of a workpiece material transparent to radiation, results in a high response rate of the temperature sensor to the temperature of the heating coil, and therefore a heating coil without hysteresis. Temperature output control is possible.In addition, a temperature sensor is installed inside the supporting stomach.
Is it possible to arrange a J? This makes it possible to eliminate harmful effects that may occur depending on the process conditions and to optimize the output control during operation of the infrared radiator.

Referring to the drawing, an electric heating coil 2 is wound around a carrier tube 1, and the carrier tube 1 is placed inside an outer tube 4 made of quartz glass by means of a space holder 3. Both ends of the mantle tube are closed by ceramic plugs 5 and 6. As is clear from the figure, the carrier tube 1 penetrates the wall of the mantle at one end thereof. A temperature sensor 7 is inserted into the carrier tube l. This temperature sensor can be displaced back and forth inside the carrier tube l even during operation of the infrared radiator, so that, for example, when using a thermoelement as a temperature sensor, the 18-temperature junction 8 is connected to the heating coil 2. The heating coil 2 can be connected to the connecting conductor 9. Connected to power via.
