Abstract
Abstract A temperature measuring device for use at pressures in excess of 1,500 bar. It comprises a thermocouple which is sheathed, the sheath being surrounded from end to end by an open ended pressure bearing sleeve. The space between the sheath and sleeve receives a hard or high temperature solder. At the outer end of the sleeve is a rigid cone or outwardly flared surface associated with a screw threaded nut which, when tightened, forces the cone against a shoulder to effect a fluid-tight connection at a point remote from the measuring junction.

Claim 1
Independent Claim
145 words
A temperature measuring device for use at pressures in excess of 1,500 bar. and for mounting in a shouldered bore leading from the outside into a high pressure equipment, said device comprising 1. a thermocouple adapted to be inserted in such bore, 2. a metallic sheath enclosing said thermocouple, 3. a metallic open-ended pressure bearing sleeve surrounding the entire length of said sheath and substantially filling such shouldered bore, 4. said pressure bearing sleeve being spaced from said metallic sheath, 5. a hard metal solder filling the space between and adhered to said pressure bearing sleeve and said sheath, 6. a cone-like surface welded to the outer end of said pressure bearing sleeve for engaging the shoulder of the bore, and 7. a screw threaded flange nut on the outer end of said thermocouple for tightening said cone-like surface against the shoulder of the bore.
