| 摘要 |
A thermoelement for measuring the temperature in gaseous or fluid media by means of one or more thermocouples comprising wires of different metals welded together which give off a resulting electrical voltage when heated and are configured as a measuring insert arranged in an insulating rod disposed in a heat-resistant protective tube that can be connected to a connection head, the protective tube being wholly or partially surrounded by a holding tube. To prevent a high input of heat which has an unfavourable effect on temperature measurement, the holding tube is supported against the protective tube at a radial distance from the protective tube, and a heat-resistant trace and optionally an insulating material are inserted between the protective tube and the holding tube, and the holding tube is attached to the connection head and/or the protective tube in one or both end areas and is provided with thermal insulation. |
