    • Method for determining a temperature in a pressurized flow path of a gas turbine (10) comprising the steps of sending an acoustic signal from an acoustic signal emitting transducer (20, 21) across a section of the pressurized flow path, detecting the acoustic signal with a receiving transducer (20, 21), measuring the time needed by the acoustic signal to travel from the acoustic signal emitting transducer (20, 21) to the receiving transducer (20, 21), calculating the speed of sound, and calculating the temperature as a function of the speed of sound, the heat capacity ratio (κ) and a specific gas constant (R spec ) of the gas flowing in the pressurized flow path.
      Gas turbine with a processor and transducers arranged to carry out such a method is disclosed.
