ABSTRACT OF THE DISCLOSURE A temperature detection pyrometer for determining the temperature of a turbine blade includes means for detecting radiation reflected and emitted from the turbine blade. The reflected radiation is a result of flame and hot carbon particles rather than the emission representing the blade temperature. The radiation is divided into two channels , each of which detects radiation in different, but preferrably overlapping wavelength bands, to detectors providing currents proportional to the radiation intensity in the respective channel. The signal from one channel is weighted with respect to the signal from the other by a constant (k) that is equal to the ratio of the radiation in the two channels which is the attributable to the reflected radiation. The difference between the signals, after weighting the one signal by the constant (k) provides an output that is a function of blade temperature only so the blade temperature may be obtained from a calibration curve or a look-up table.
