Temperature measuring device

Claim 1

In a thermocouple assembly adapted to be positioned adjacent a conduit in order to make temperature measurements at the surface of said conduit, the combination of: a thermocouple junction having a pair of electrical leads therefrom positioned within an insulated cable, said cable being inserted within a hollow deformable jacket with said junction positioned adjacent one end of said jacket, said jacket being so curved as to be correlative in configuration to and adapted to be positioned around at least a portion of said conduit; a concave thermocouple junction positioning member having a slotted portion, said slot extending in a direction perpendicular to the axis of said conduit when said jacket is positioned therearound, said slotted portion receiving said thermocouple junction containing one end of said jacket therewithin, said positioning member''s concavity being correlative with the convex outer surface of said conduit; and an insulated shield of arcuate configuration correlative to that of and positionable circumferentially around at least a portion of said conduit, said shield having first and second ends, said first end forming a solid wall, said second end forming a solid wall but for an approximately semi-annular cutaway of a size adapted to clampingly press said jacket against said conduit, said shield being substantially filled with insulating material but for a circumferentially extending semi-annular cutaway portion, to accommodate said jacket, extending from said second wall cutaway to near said first wall, said circumferentially extending cutaway terminating in a further cutaway portion of said insulating material, said further cutaway portion being of approximately the size and configuration of said positioning member, said thermocouple junction containing jacket and said positioning member being positioned within said semi-annular cutaway and said further cutaway portion respectively whereby said thermocouple junction received by said positioning member is held in close proximity to the outer surface of said conduit.
