ABSTRACT:
A self-contained temperature probe assembly for sensing the disc cavity temperature of a gas turbine engine is shown. The assembly includes a thermocouple probe comprising an upper tube and a lower tube housing the probe leads. The lower tube extends from the cylinder housing through the blade ring to guide the probe tip through a hollow vane to adjacent a rotor disc and includes a tapered portion for sealing engagement with a tapered aperture in the blade ring as biased by a coil spring. The upper tube extends outwardly from the turbine cylinder to the probe head. The adjacent ends of the two tubes are retained in a standard flange in predetermined spaced relation against outward withdrawal and the lead wires are coiled within the space to maintain a slack condition to prevent transmission of vibration of the lead wires into the probe head and also prevent the rather fragile wires from supporting any weight of the probe during shipping or installation of the probe to the turbine.
