Abstract

A thermometer with protective tube inner part for insertion into a protective tube, especially a protective tube of a thermometer, wherein the protective tube inner part serves for arranging conductor elements, and wherein the protective tube inner part is matched to the shape of the inside of the protective tube in the region of a closed, protective tube end, and wherein the protective tube inner part serves to arrange the conductor elements on the side of the protective tube inner part facing the protective tube in the installed state.

Claims (46)

1. A thermometer comprising a protective tube inner part for insertion into a protective tube, wherein:

the protective tube inner part serves for arranging conductor elements;

the protective tube inner part is matched to the shape of the inside of said protective tube in the region of a closed, protective tube end; and

the protective tube inner part serves to arrange said conductor elements on the side of the protective tube inner part facing said protective tube in the installed state,

said protective tube is sealed on one of its ends by a lid,

and wherein a system for determining pressure in said protective tube is provided in said lid, or connecting lines to such a system are provided in said lid.

2. The thermometer as claimed in claim 1 , wherein:

said conductor elements form a sensor element or a number of sensor elements.

3. The thermometer as claimed in claim 2 , said sensor element comprises at least one thermoelement or at least one temperature dependent, resistance element.

4. The thermometer as claimed in claim 1 , wherein:

said conductor elements are so arrangeable on the side of the protective tube inner part facing, in the installed state, said protective tube that said conductor elements are in thermal contact with said protective tube.

5. The thermometer as claimed in claim 1 , wherein:

the protective tube inner part is connected with the inside of said protective tube force interlockingly, wherein the protective tube inner part is held in place against the inside of said protective tube via spring force.

6. The thermometer as claimed in claim 1 , wherein:

said conductor elements are in thermal contact with said protective tube via a potting compound.

7. The thermometer as claimed in claim 1 , wherein:

said conductor elements are arranged by means of the protective tube inner part between the wall of said protective tube and the wall of the protective tube inner part.

8. The thermometer as claimed in claim 1 , wherein:

the hollow space formed by said protective tube is evacuated or evacuable.

9. The thermometer as claimed in claim 1 , wherein:

said protective tube end has a cupola-like shape on its outside.

10. The thermometer as claimed in claim 1 , wherein:

a plurality of lamellae are arranged, within said protective tube.

11. The thermometer as claimed in claim 1 , wherein:

said protective tube and/or the protective tube inner part have/has on the outside, at least in the region of said protective tube end exposed during operation to the measured material, a coating, wherein said coating is gold or chrome.

12. A container having at least one thermometer as claimed in claim 1 , wherein:

a receptacle is provided, into which the thermometer is insertable, wherein the receptacle is a component of the wall of the container.

13. A system comprising a pouch or a container having an at least sectionally flexible wall for accommodating a measured material and a thermometer as claimed in claim 1 , wherein:

the thermometer is introducible into a receptacle of the pouch or of the container, so that it at least sectionally lies flushly against the pouch, or against the flexible wall of the container.

14. The system as claimed in claim 13 , wherein:

the receptacle has, for the securement of the thermometer, securement elements, by which the thermometer is connected or connectable, preferably force interlockingly, with the pouch, or the flexible wall of the container.

15. The thermometer as claimed in claim 1 , wherein the protective tube inner part has a cup-like shape.

16. The thermometer as claimed in claim 1 , wherein the protective tube inner part is matched to a correspondingly formed inside of said protective tube end.

17. The thermometer as claimed in claim 1 , wherein:

the protective tube inner part comprises a heat-conductive and/or electrically insulating material, wherein said insulating material is a ceramic.

18. The thermometer as claimed in claim 1 , wherein:

the protective tube inner part has a metal or glass-ceramic coating at least on the side facing in the installed state away from the protective tube.

19. The thermometer as claimed in claim 1 , wherein:

the protective tube inner part has guiding elements, which serve to arrange said conductor elements in a desired arrangement; and

wherein said conductor elements are introducible with an accurate fit into said guiding elements.

20. The thermometer as claimed in claim 19 , wherein:

said guiding elements comprise at least one cavity in the protective tube inner part for accommodating said conductor elements.

21. A thermometer comprising a protective tube inner part for insertion into a protective tube, wherein:

the protective tube inner part serves for arranging conductor elements;

the protective tube inner part is matched to the shape of the inside of said protective tube in the region of a closed, protective tube end; and

the protective tube inner part serves to arrange said conductor elements on the side of the protective tube inner part facing said protective tube in the installed state, wherein a plurality of lamellae are arranged in a hollow space of said protective tube and serve to lessen thermal radiation present in the interior of the protective tube.
