Emissivity measurement for outdoor structures

Emissivity measurement for outdoor structures

The author tests a radiometric method of measuring emissivity for outdoor structures. The method measures emissivity from the functional relationship between the brightness of the emission from a source with a known standard emitter and the temperature which is the same as that for the working surfa...

Zusammenfassung:The author tests a radiometric method of measuring emissivity for outdoor structures. The method measures emissivity from the functional relationship between the brightness of the emission from a source with a known standard emitter and the temperature which is the same as that for the working surface with its coating. The standard sources were provided by special paint coatings whose emissivities were 0.40-0.95. A portable pyrometer was used for the measurements. The radiation temperature and the brightness in relation to the emissivity are shown, as are the coating temperatures as functions of emissivity.
