Abstract: THE DISCLOSURE SHOWS A TEMPERATURE SENSOR FOR OBTAINING A MEASUREMENT OF THE TEMPERATURE OF A HOT GAS STREAM ENTERING THE TURBINE OF A GAS TURBINE ENGINE. THE SENSOR COMPRISES A POWER NOZZLE WHICH IS CONNECTED TO THE HOT GAS STREAN OF THE ENGINE. THE FLUID STREAM DISCHARGED ROM THE NOZZLE IMPINGES ON A V-SHAPED DIVIDER SPACED OUTWARDLY THEREFROM. THE DIVIDER CAUSES THE POWER STREAM TO ALTERNATELY PRESSURIZE ELONGATED CHAMBERS ON OPPOSITE SIDES THEREOF. THESE CHAMBERS ARE VENTED BY VENTS HAVING A COMBINED AREA APROXIMATELY ONE-HALF THE AREA OF THE NOZZLE. AN OUTPUT PRESSURE SIGNAL IS DERIVED FROM ONE OF THE CHAMBERS. THE RATE AT WHICH THIS PRESSURE SIGNAL VARIES GIVES AN ACCURATE MEASUREMENT OF THE TEMPERATURE OF THE HOT GAS STREAM IN THE TURBINE ENGINE. A GRANSDUCER IS EMPLOYED TO PROVIDE AN ANALOG READOUT OF THE MEASUREMENT.
