Abstract
Abstract A probe tube which is introduced into a reaction container for measuring the operating condition of a medium in the interior of the container has a first seal which is resistant to temperature and a second seal which is resistant to pressure and gas-tight. Those seal respectively close the inner and outer ends of the probe tube. The interior of the probe tube communications with the interior of the reaction container by way of an opening, whereby the temperature-resistant seal at the tip of the probe tube is relieved of the loading of pressure forces.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
175 words
A probe tube which can be introduced into a reaction container for detecting the operating condition of a solid, liquid or gaseous medium in the interior of the container under pressure and temperature, the probe tube having a measuring sensor at one end and measuring lines which are passed through the interior of the probe tube and taken out at the other end thereof, characterised in that the probe tube (10) is provided with a first sealing means in the region of the measuring sensor (2) which is resistant to temperature and a second sealing means proximate the other end which is resistant to pressure and is gas-tight, the interior (6) of the probe tube (10) between the two sealing means being filled with a medium substantially resistant to pressure and temperature and different from the medium within the reaction container which communicates with the medium in the interior of the reaction container (8) by way of an opening (11) having a diameter that is small in comparison to the length of the probe tube.
Claim 2
Dependent Claim
175 words
A probe tube which can be introduced into a reaction container for detecting the operating condition of a solid, liquid or gaseous medium in the interior of the container under pressure and temperature, the probe tube having a measuring sensor at one end and measuring lines which are passed through the interior of the probe tube and taken out at the other end thereof, characterised in that the probe tube (10) is provided with a first sealing means in the region of the measuring sensor (2) which is resistant to temperature and a second sealing means proximate the other end which is resistant to pressure and is gas-tight, the interior (6) of the probe tube (10) between the two sealing means being filled with a medium substantially resistant to pressure and temperature and different from the medium within the reaction container which communicates with the medium in the interior of the reaction container (8) by way of an opening (11) having a diameter that is small in comparison to the length of the probe tube.
Claim 3
Dependent Claim
23 words
A probe tube according to claim 1 characterised in that the medium in the interior (6) of the probe tube is an oil.
Claim 4
Dependent Claim
13 words
A probe tube according to claim 2 wherein the oil is mineral oil.
Claim 5
Dependent Claim
18 words
A probe tube according to claim 1 characterised in that the first sealing means comprises a two-component adhesive.
Claim 6
Dependent Claim
19 words
A probe tube according to claim 1 characterised in that the second sealing means (17) comprises a two-component adhesive.
Claim 7
Dependent Claim
145 words
A probe tube which can be introduced into a reaction container for detecting the operating condition of a solid, liquid or gaseous medium in the interior of the container under pressure and temperature, the probe tube having a measuring sensor at one end and measuring lines which are passed through the interior of the probe tube and taken out at the other end thereof, characterised in that the probe tube (10) is provided with a first sealing means in the region of the measuring sensor (2) which is resistant to temperature and a second sealing means proximate the other end which is resistant to pressure and is gas-tight, the interior (6) of the probe tube (10) between the two sealing means being filled with an oil which communicates with the medium in the interior of the reaction container (8) by way of an opening (11).
Claim 8
Dependent Claim
145 words
