Abstract
A thermocouple probe assembly for monitoring the temperature of an exhaust gas flow at an output of a gas turbine engine. The probe assembly includes a plenum pipe positioned within an opening extending through an outer casing wall and a plenum plate of the engine, where an air gap is provided between the casing wall and the plate. The plenum pipe is rigidly secured to the plenum plate and resiliently mounted to the casing wall so that the plenum pipe is operable to slide relative to the wall. The probe assembly further includes a diffuser liner boss rigidly secured to an outer liner of an exhaust gas diffuser in the gas turbine engine, where the liner boss includes a central bore, and where the shaft of the thermocouple probe extends through the central bore in the liner boss so that the sensor is positioned within the exhaust gas diffuser.
