本文根据双色温度测量的概念,介绍我们研制的光纤非接触温度测量系统的原理。在此基础上,提出了一种以双路温度信号比值运算为特点的新结构型光纤温度测量仪的设计方法。给出了系统温度分度与感温探头抗干扰等特性的实验结果。
Based on the concept of two-color temperature measurement, this paper introduces the principle of optical fiber non-contact temperature measurement system. On this basis, a new design method of optical fiber temperature measuring instrument based on the ratio of two-way temperature signal is proposed. The experimental results of system temperature indexing and anti-interference of temperature probe are given.
