New Colorimetric Pyrometer with Optical Fiber Link

Based on the concept of thermo-radiation theory,the principle of non-contact temperature measurement with optical fiber is introduced.The new pyrometer operates on the basis of two-way temperature signal division calculation via microcomputer signal processing system.Its design method and smart construction of the electro-optical system possess such advantages as high measurement accuracy,freedom from electric interference and other perturbations as well as flexible applications.The indication scale of the measured temperature and experiment results are given in this paper.
