    摘要： Systems and methods are provided to detect a failed thermocouple. A temperature in a gas path of a gas turbine engine may be measured, where the temperature is based on a signal generated by a thermocouple during a startup of the gas turbine engine and/or during an idle period that immediately follows the startup, and the thermocouple protrudes into the gas path. A failure of the thermocouple may be detected if the temperature is determined to be less than a threshold temperature.

    摘要： A cooled thermocouple arrangement (1) including a thermocouple (2) comprising two wires (3,4) joined at a first sensing end (5) to define a hot thermocouple function. At least a portion of the wires (3,4) are in thermal communication with a cooling arrangement, and the cooling arrangement has an inlet (14) for coolant and an outlet (15) for coolant. The thermocouple probe arrangement (1) includes a first inlet temperature sensor (21) for determining the temperature of the coolant as it enters the cooling arrangement, and a flow rate sensor (20) for determining the flow rate of coolant passing through the cooling arrangement. The thermocouple probe arrangement (1) includes connectors for connecting the outputs from the thermocouple (2), first inlet temperature sensor (21) and the flow rate sensor (20) to a correction data processor (23) whereby the data processor can correct the temperature sensed by the thermocouple to take account of the effect of the cooling arrangement. The pair of thermocouple wires (3,4) are arranged inside a sheath or casing, and a cooling jacket (12) is provided around the thermocouple probe. The cooling jacket (12) includes a pair of concentric tubes (16,17) defining a return coolant circuit from the end of the probe proximal the connectors (8), to a portion of the probe distal from the connectors, and then back to the proximal end (8) of the probe, and the portion of the thermocouple probe containing the sensing end (5) of the thermocouple projects from the distal end of the cooling jacket (12).

    摘要： A thermocouple having a support tube configured to receive a pair of wires of dissimilar metals. The pair of wires of the thermocouple connected at a junction adjacent to one end of the support tube. The thermocouple further including a cap attached to the opposing end of the support tube, wherein the cap receives the free ends of the pair of wires. The cap allowing the pair of wires to translate freely therethrough to accommodate the difference in thermal expansion and contraction of the pair of wires relative to the thermal expansion and contraction of the support tube.
