Abstract
The invention relates to a method for determining the temperature of a surface coating of rotating blades mounted in a non-positive-displacement machine with a rotor shaft rotationally mounted in a housing, during which electromagnetic waves are emitted in a duct in an area of the rotating blades by at least one means for generating electromagnetic waves. The electromagnetic waves are reflected, at least in part, by at least one rotating blade. The reflected portions of the electromagnetic waves are received by at least one receiving means and the temperature of the surface coating of the rotating blades is determined from a distribution of intensity of the received electromagnetic waves. The invention also relates to a method for determining the temperature of a surface coating of guide vanes mounted in a rotationally fixed manner in a non-positive-displacement machine with a housing, and to a device for carrying out the method.
