Abstract
Abstract The wet bulb thermometer of a psychrometer comprises a measuring portion mounted within a permeable sleeve which is high temperature resistant and which has a base portion extending outside the chamber containing the gaseous substance whose relative humidity is to be measured, the base portion being continuously traversed by flowing water so that the sleeve is always wetted.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
In an apparatus for continuous measurement of the moisture content of a gaseous substance in a high temperature chamber at atmospheric pressure wherein a psychrometer with wet bulb and dry bulb thermometers is provided within an atmosphere of the gaseous substance to be measured, an improvement comprising a measuring element for the wet bulb temperature, a sleeve comprising spaced wire nets and high-temperature-resistant capillary material between said nets, said measuring element being detachably inserted in said sleeve, said sleeve including a base portion extending outside said chamber, and means for passing water over said base portion of said sleeve at a predetermined water pressure and at a predetermined flow rate for wetting the sleeVe and maintaining the same always in a predetermined wet condition.
Claim 2
Dependent Claim
124 words
In an apparatus for continuous measurement of the moisture content of a gaseous substance in a high temperature chamber at atmospheric pressure wherein a psychrometer with wet bulb and dry bulb thermometers is provided within an atmosphere of the gaseous substance to be measured, an improvement comprising a measuring element for the wet bulb temperature, a sleeve comprising spaced wire nets and high-temperature-resistant capillary material between said nets, said measuring element being detachably inserted in said sleeve, said sleeve including a base portion extending outside said chamber, and means for passing water over said base portion of said sleeve at a predetermined water pressure and at a predetermined flow rate for wetting the sleeVe and maintaining the same always in a predetermined wet condition.
Claim 3
Dependent Claim
40 words
An improvement as claimed in claim 1 wherein said means for passing water over said base portion of said sleeve comprises a water passage at said base portion and a water conduit connected to said passage for passing water therethrough.
Claim 4
Dependent Claim
28 words
An improvement as claimed in claim 2 comprising a mouthpiece outside said chamber supporting said base portion of the sleeve, and means mounting said mouthpiece on said chamber.
Claim 5
Dependent Claim
24 words
An improvement as claimed in claim 3 comprising cooling means surrounding said mouthpiece to prevent overheating thereof by the gaseous substance in the chamber.
Claim 6
Dependent Claim
34 words
An improvement as claimed in claim 3 wherein said sleeve and measuring element are tilted downwardly such that the end of the sleeve remote from said base portion is lower than said base portion.
Claim 7
Dependent Claim
21 words
An improvement as claimed in claim 3 wherein said sleeve has an end remote from said base portion which is closed.
Claim 8
Dependent Claim
13 words
An improvement as claimed in claim 3 comprising a filter surrounding said sleeve.
Claim 9
Dependent Claim
29 words
An improvement as claimed in claim 3 wherein said chamber includes a channel in which the gaseous substance continuously flows, said mouthpiece and sleeve being mounted on said channel.
Claim 10
Dependent Claim
165 words
In an apparatus for continuous measurement of the moisture content of a gaseous substance in a high temperature chamber at atmospheric pressure wherein a psychrometer with wet bulb and dry bulb thermometers is provided within an atmosphere of the gaseous substance to be measured, an improvement comprising a measuring element for the wet bulb temperature, a sleeve constituted of high-temperature-resistant capillary material, said measuring element being detachably inserted in said sleeve, said sleeve including a base portion extending outside said chamber, means for passing water over said base portion of said sleeve at a predetermined water pressure and at a predetermined flow rate for wetting the sleeve and maintaining the same always in a predetermined wet condition, a mouthpiece outside said chamber supporting said base portion of the sleeve, means mounting said mouthpiece on said chamber, and heat insulation means within said chamber shielding the mouthpiece in the region of the base of the sleeve from heat effect of the gaseous substance in the chamber.
