Experimental Study of Static Calibration Based on Atomic- emission Double Spectrum Line Temperature Measuring System

摘要

Based on the double line of atomic emission temperature measurement technology, combined with storage measurement technology, the photoelectric thermometer was designed by using Y-type fiber, narrow band filter, silicon photomultiplier tube (SiPM). Record the temperature value measured by the photo thermometer and the temperature value displayed on the LCDpanel of the chamber furnace, and obtain the static sensitivity coefficient K by the least squares method. The temperature indicated by the high-temperature box furnace is used as the standard temperature value. A static calibration system is built. The temperature of the heated copper sheet was measured using a statically calibrated photometric temperature measurement system and compared with the measurement results of the M5 infrared. The experimental results verify the feasibility of temperature measurement system. The research work in this paper has important reference value for the development of temperature measurement technology ofatomic emission spectroscopy.
