Abstract
The results of a study of remote temperature measurement systems of industrial electrical installations based on bolometric photodetector cameras are presented. A photodetector thermal imager camera of the FLIR system and a specialized radiometric thermal imager with internal temperature sensors and calibration shutters are considered. The best coating for calibration shutters with a minimum level of reflection of IR radiation from their surface has been determined (the integral reflection coefficient in the spectral range of 8-14 microns is no more than 5.8%). A mathematical description of the calibration process of the thermal imager camera of the FLIR system in a wide range of temperature changes of its components and the ambient medium is given. The requirements to the thermal imager camera for remote temperature diagnostics systems of industrial installations are analyzed.
