Abstract: The present invention provides a thermocouple rake that may readily be removed and reinstalled into a separate turbine. Further, a cantilevered thermocouple rake is provided, wherein the installed rake requires fixation at only one end. A thermocouple rake consistent with the invention also comprises a plurality of rigid guide and support tubes for strength and stiffness, and comprises a plurality of thermocouple junctions in each guide tube at different lengths along the tube, for taking readings at various distances from the turbine wall. The present invention further provides a thermocouple rake having tubing of various diameters to protect against vortex shedding. A plurality of spacers serve as damping during vibration allowing the rake (or at least a portion thereof) to survive vibration at its natural frequency. A stop and tapered bushing configuration effects better damping and longevity in high vibration environments, e.g., in gas turbines.
