Two-color ratio pyrometer with optical fiber for over-heating gas

摘要

An optical fiber pyrometer prototype for accurate measurement of over-heating gas temperature has been developed in this paper. The paper describes the development of novel optical fiber pyrometer and its technique, which could have the potential of measuring temperatures up to 2000$DGR@C. The working principle of the pyrometer is based on Plarck's Law. The test results are presented.
