Investigation of thermal radiation and temperature measurement by optical pyrometer


Investigation of thermal radiation and temperature measurement by optical pyrometer.


Heated body with temp. T in environment of tem. T0 then its emittance is:

If the body is heated with current I and at voltage U, than its emittance is:

Now we need to measure electric circuit parameters I, U and temperatures of the body and environment.

Preparation of the Pyrometer device. The lamp wire is heated to 500 degrees and through red filter with ocular help we focus sharp view of glowing wire.

With ocular focus the image of the investigating lamp wire so that it would overlap with glowing red wire.
