摘要

基于原子发射双谱线测温原理, 提出了基于硅光电倍增管的光电测温系统, 介绍了该测温装置的结构及测温原理。基于原子光谱数据库选择Al I 690.6 nm和Al I 708.5 nm作为测温时的温标谱线, 通过光电测温计测量铝在纯氧中燃烧时的温度, 并将其与热电偶测量的温度进行对比。结果表明, 两种方法测得温度的平均相对误差为1.5%, 证明了基于原子发射双谱线测温技术的可行性。

Abstract

Based on the temperature measurement principles of double line of atomic emission spectrum, the photoelectric pyrometer based on silicon photomultiplier is proposed, and the structure and temperature measurement principle of the photoelectric pyrometer are introduced. Al I 690.6 nm and Al I 708.5 nm are selected from the atomic spectra database as the temperature measurement element spectral lines. The temperatures of aluminum burnt in pure oxygen are obtained by photoelectric thermometer and compared with temperatures measured by the thermocouple. The results show that the average relative error of temperatures measured by the two methods is 1.5%, which proves the feasibility of the proposed method.
