Temperature measuring apparatus
First Claim
1. An apparatus for measuring the temperature of a fluid environment within a vessel, said apparatus comprising:
- (a) a chamber means that is sealingly connected to and which opens into said vessel to form a chamber which contains a portion of said fluid environment;
(b) a temperature sensing means which is movable between a first and a second position, whereby at said first position,(i) at least a portion of said temperature sensing means is within said chamber, and(ii) said temperature sensing means is out of contact with the remainder of said fluid environment, and whereby at said second position,(iii) at least a portion of said temperature sensing means is exterior of said chamber and is in contact with said remainder of said fluid environment so as to obtain said temperature measurement;
(c) means for preventing substantial convective movement between said portion of said fluid environment and said remainder of said fluid environment when said temperature sensing means is moving between and at said first and second positions; and
(d) means for maintaining said portion of said fluid environment in said chamber at a cooler temperature than the temperature of said remainder of said fluid environment.

Abstract
This invention relates to an apparatus and process for measuring the temperature of a fluid environment within a vessel. The apparatus features a chamber which opens into the vessel and thus contains a portion of the fluid environment. Structure is provided for preventing substantial convective movement between the portion of the fluid environment within the chamber and the remainder of the fluid environment. A temperature sensing device is also provided which is movable from a position within the chamber to a position into the remainder of the fluid environment for obtaining a temperature measurement. The chamber is maintained at a temperature cooler than that of the fluid environment. This invention also relates to a process for the periodic measuring of the temperature of a fluid environment in a vessel. The process features locating at least a portion of a temperature sensing device in a chamber which opens into the fluid environment and which chamber is kept at a lower temperature than the fluid environment by maintaining that portion of the fluid environment within the chamber and the remainder of the fluid environment in the vessel whereby they are substantially free of convective movement with respect to one another.

11. A process for the periodic measuring of the temperature of a fluid environment in a vessel, said process comprising:
-
(a) providing a chamber that is sealingly connected to said vessel and which opens into said fluid environment, said chamber thereby containing a portion of said fluid environment; (b) locating at least a portion of a temperature sensing means in said chamber; (c) maintaining said portion of said fluid environment in said chamber and the remainder of said fluid environment substantially free of convective movement with respect to one another while said temperature sensing means is moving between and is at said points in (d) and (f); (d) moving from said chamber at least a portion of said temperature sensing means to a point within said remainder of said fluid environment whereby said temperature sensing means is positioned to provide the required output for obtaining said temperature measurement; (e) obtaining said temperature measurement; and (f) returning to said chamber that portion of said temperature sensing means moved to said point in (d), subsequent to said obtainment of said temperature measurement. - View Dependent Claims (12, 13)
