Abstract

The invention relates to an apparatus for determining and/or monitoring a temperature of a medium in a containment, comprising a measuring insert having a temperature sensor for registering temperature, a protective tube, in which the temperature sensor is arranged, and a heat conductive, formed piece, which is arranged in the protective tube and surrounds the measuring insert at least sectionally.

First claim

1 - 15 . (canceled)

16 . An apparatus for determining or monitoring a temperature of a medium in a containment, comprising:
a measuring insert having a temperature sensor for registering temperature; a protective tube, in which the temperature sensor is arranged; and a heat conductive, formed piece, which is arranged in the protective tube and surrounds the measuring insert at least sectionally.

17 . The apparatus as claimed in claim 16 , wherein the formed piece is made of copper, silver, graphite, boron nitride, a steel, or an alloy containing at least one of these materials.

18 . The apparatus as claimed in claim 16 , wherein the formed piece is at least sectionally tubular, especially cylindrical.

19 . The apparatus as claimed in claim 16 , wherein the formed piece is pot shaped.

20 . The apparatus as claimed in claim 19 , wherein a floor of the formed piece has a bore, along which the measuring insert is guidable.

21 . The apparatus as claimed in claim 16 , wherein the formed piece has at least sectionally a geometry corresponding to a geometry of the protective tube or the measuring insert.

22 . The apparatus as claimed in claim 16 , wherein the formed piece includes an endpiece, whose outer diameter is greater than an outer diameter of the formed piece in a middle region of the formed piece.

23 . The apparatus as claimed in claim 22 , wherein the endpiece is disc shaped.

24 . The apparatus as claimed in claim 22 , wherein a geometry of the endpiece at least partially corresponds to a geometry of the protective tube in a region, into which the formed piece is introducible.

25 . The apparatus as claimed in claim 16 , further comprising a securement component for securing of the formed piece in the protective tube or on the measuring insert.

26 . The apparatus as claimed in claim 25 , wherein the securement component is embodied and arranged in such a manner that by using the securement component a compressive force is exertable on the formed piece.

27 . The apparatus as claimed in claim 25 , wherein the securement component has at least one basic body, which is arrangeable around the formed piece in the protective tube.

28 . The apparatus as claimed in claim 27 , wherein the basic body is formed of a plastic.

29 . The apparatus as claimed in claim 27 , wherein the securement component has at least one spring, by which the predeterminable compressive force is suppliable using the basic body.

30 . The apparatus as claimed in claim 16 , wherein the temperature sensor comprises at least one resistance element or thermocouple.
