Working Principle
The Emissivity Measurement Apparatus works on the principle of radiation comparison between two plates:
-
The test plate contains a mica heater sandwiched between circular metal plates.
-
The black reference plate is identical in material, dimensions, and physical properties, with the only difference being its blackened surface.
-
Both plates are mounted in individual brackets within a glass-enclosed chamber to maintain consistent atmospheric conditions.
-
Electrical power is supplied to the heaters using separate variacs. Temperatures are kept equal, and differences in power input reflect the emissivity difference between the plates.
-
Temperature sensors measure each plate and the surrounding air temperature to calculate emissivity accurately.
-
The experiment enables determination of emissivity and observation of how it varies with absolute temperature.
This method ensures high precision by eliminating heat loss differences unrelated to emissivity, allowing accurate experimental results.
Applications
The Emissivity Measurement Apparatus is widely used in:
-
Engineering Colleges & Universities: For teaching principles of heat radiation and thermal engineering.
