Method for controlling a gas turbine and gas turbine for implementing the method

The method involves forming derivation of hot gas temperature at different areas of a gas turbine (10) over pressure measurements by pressure sensors (P1-P3). The pressure measurements are executed in a hot gas flow produced in a combustion chamber (13) of the turbine and directly before a blade series of the turbine. A pressure drop is determined between measuring positions that lie downstream to fire (18) present in the chamber. A turbine flange (14) is arranged in the turbine at a transition between the chamber and the turbine. An independent claim is also included for a gas turbine for executing a regulation method.
