Abstract
Abstract A temperature sensing device for a thin-walled pressure vessel is provided. This device comprises an insert segment which lies inside the pressure vessel in heat exchange relation with the fluids contained by the vessel, an outer segment disposed outside of the pressure vessel, a linking segment normally disposed in a port through the side wall of the pressure vessel for connecting the outer segment with the insert segment, and a temperature sensing device connected to the outer segment. The device also includes an o-ring disposed around the linking portion and forming a seal between the linking portion and the sidewalls of the port.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
154 words
A temperature sensing device for a thin-walled thermoplastic pressure vessel which contains fluids at high pressures and temperatures and which has a port through its sidewall, said sensing device comprising: an insert segment for positioning in said pressure vessel in heat exchange relation with the fluids contained in said vessel; an outer segment placed outside of said pressure vessel; a linking segment disposed within the port in the sidewall of said pressure vessel and connecting said insert and outer segments; said insert portion, said linking portion, and said outer portion being made of material having a high thermal conductivity; sealing means disposed around said linking portion for providing a leak-proof seal between said linking portion and the walls of said port through said pressure vessel; and a temperature sensory device mounted in contact with said outer segment to measure the temperature of said outer segment which corresponds to the temperature of said vessels contents.
Claim 2
Dependent Claim
154 words
A temperature sensing device for a thin-walled thermoplastic pressure vessel which contains fluids at high pressures and temperatures and which has a port through its sidewall, said sensing device comprising: an insert segment for positioning in said pressure vessel in heat exchange relation with the fluids contained in said vessel; an outer segment placed outside of said pressure vessel; a linking segment disposed within the port in the sidewall of said pressure vessel and connecting said insert and outer segments; said insert portion, said linking portion, and said outer portion being made of material having a high thermal conductivity; sealing means disposed around said linking portion for providing a leak-proof seal between said linking portion and the walls of said port through said pressure vessel; and a temperature sensory device mounted in contact with said outer segment to measure the temperature of said outer segment which corresponds to the temperature of said vessels contents.
Claim 3
Dependent Claim
18 words
