Abstract
A method for determining temperature in a flow channel of a gas turbine positioned on a testing bench includes: arranging at least one rod-shaped element provided with a thermal paint coating inside the flow channel; operating the gas turbine on the testing bench in a defined operating mode, wherein the thermal paint coating of the at least one rod-shaped element changes its color depending on the temperature that the thermal paint coating is exposed to; detecting the color distribution of the thermal paint coating of the at least one rod-shaped element; and determining the temperature that has been present in the flow channel along the at least one rod-shaped element in the defined operating mode based on the detected color distribution. Another embodiment relates to a measuring device having a rod-shaped element provided with a thermal paint coating.
