Abstract
A possibility of using non-monochromatic photodetectors capturing radiation in a wide range of wavelengths as sensors of the brightness channel in spectral brightness pyrometry is considered. A definition of the effective wavelength of the pyrometer is introduced on the basis of the dependence of the detected signal on the temperature of the heat source. Experimental results on determining the effective wavelength of the photodetector with the sensitivity in the interval of 400 - 1100 nm in recording the temperature lamp radiation in the temperature range from 1557 to 2494 K are reported.
