Thermoelement
First Claim
1. A thermoelement for measuring the temperature of gaseous or fluid media by means of at least one or more thermocouples comprising wires of different metals welded together to provide a resulting electrical voltage when heated, and comprising a measuring insert wherein there is disposed an insulating rod within a heat-resistant protective tube connected to a connection head, the protective tube being at least in part surrounded by a holding tube,wherein the holding tube is supported around the protective tube, radially of the protective tube, and around a heat-resistant trace disposed within the holding tube, and an insulating material disposed between the protective tube and the holding tube, the holding tube is being attached to at least one of the connection head and the protective tube in at least one end area thereof;
- wherein the trace is of a selected one of a heat-resistant and ceramic material; and
is arranged in a helical manner between the protective tube and the holding tube.

Abstract
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.
