摘要： An arrangement to prevent thermocouple chafing with a guide tube within a rotor disc cavity during gas turbine operation is provided. The arrangement includes an interstage seal housing, a guide tube, and a thermocouple including a tip portion, an elongated portion, a head portion, and an antichafing strip. The guide tube is disposed in a radially extending bore of the interstage seal housing. The tip portion extends radially inward into the rotor disc cavity, the elongated portion is disposed at least partially within the guide tube, and the head portion is disposed radially outward of the casing. The tip portion includes a temperature sensing element which measures the temperature of the rotor disc cavity. The antichafing strip is disposed along the length of the elongated portion so that it is at least partially disposed within the guide tube. A method to prevent premature gas turbine shutdown due to thermocouople failure is also provided.

摘要： A temperature probe includes an elongated longitudinal tubular shaft having a hollow interior, an insulating structure mounted on the elongated shaft, and a heat conducting structure constructed of a metallic material coupled to the insulating structure. A thermocouple is coupled to the heat conducting structure and extends into the hollow interior of the elongated shaft. A control device is electrically communicated to the thermocouple and is operable to determine a temperature from the thermocouple. When the heat conducting structure is disposed within a mass of packed product, the heat conducting structure transmits thermal energy from the mass to the thermocouple and the insulting structure thermally isolates the heat conducting structure from the tubular shaft.

摘要： A tapered, nonconductive structure (10) having a hollow core (18) and a conical tip (14) includes a metal wire (16) within the core (18). The wire (16) is sealed within, and is exposed at the end (22) of, the tip (14). An electrically conductive or semiconductive layer (24) on the exterior of the tip (14) form a point thermocouple contact with the wire. The tip (14) may be fabricated, for example, by placing a metal wire (16) within a tube (12), and heating and pulling the tube (12) to produce two tapered micropipettes. Thereafter, a thin metal or semiconductor film (24) is evaporated onto the outer surface.

摘要： A surface thermocouple assembly including a metal sheath having thermocouple conductors extending therethrough in spaced relation from each other and from the sheath by electrical insulating material, an opening in the sheath wall at the hot junction end and through which the conductors are extended, a ceramic plug receiving the conductors and mounted in the opening, a fusion weld of the conductors outside the plug, and a V-shaped pad with a knife-shaped edge integrally formed at the junction end. The thermocouple is made from a length of sheathed thermocouple conductors by forming a keyhole slot at the junction end, removing the insulation around the conductors, bending the conductors through the opening of the keyhole slot, mounting a ceramic plug in place, fusion welding the ends of the conductors outside the plug to define the thermojunction, inserting a metal end plug at the junction end, welding closed the slot and the end plug in position, and building up a V-shaped welded pad at the hot junction end. Thereafter, mounting of the thermocouple assembly onto a surface for which the temperature is to be monitored includes the positioning of the hot junction end onto the tube with the knife-shaped edge of the pad in engagement with the tube, and providing void-free welds between the pad and the tube such that the distance between the thermojunction and the tube surface is substantially less than the distance between the junction and the closest free surface of the mounting welds.
