| Abstract: | Temperature measurement technique based on the principles of optical spectroscopy was discussed and the spectroscopic pyrometer developed thereunder was presented. Temperature distribution in arc or RF plasma torch which conform to local thermodynamic equilibrium and axis--symmetry can be obtained with this pyrometer. The measurement range is 5000~15000 K and the uncertainty of measurement is 2.2 %. |
