FIELD: physics.
SUBSTANCE: in compliance with this method, filament current is fed to standard lamp only in conditions of pyrometer calibration conditions to register object brightness by multi-element matrix or linear photo receiver. Image of standard lamp filaments is projected on portion of photocells of said photo receiver. Standard lamp filament current in calibration conditions is varied by linear law. Filament current and photo receiver output signal related therewith are numbered and memorised in calibration, during filament current increment while, in measurement conditions, object temperature is defined from peak-to-peak output signal ui and ui+1, proximate to signal measured magnitude.
EFFECT: higher accuracy of measurement.
