A fluidic oscillator temperature sensor assembly for determining the average temperature of a stream of flowing gas in a conduit such as the turbine inlet of a gas turbine engine comprises a source of pressurized gas, a fluid amplifier connected to the source for utilizing the pressurized gas as a power stream, at least one feedback tube adapted for support across a desired cross-sectional area of the conduit connected to the fluid amplifier for oscillating the flow of the power stream at a frequency varying directly as a function of the temperature in the feedback tube, the feedback tube having a plurality of perforations along its length for admitting the flowing gas into the feedback tube to render the temperature therein substantially identical with the average temperature of the flowing gas and means for sensing the frequency to determine the average temperature.
