摘要
中温光纤辐射测温仪,用国产石英光纤作光路,硫化铅探测器作光敏元件,实现了200℃以上,1℃分辨率的温度检测。文中提出一种新的、实用的桥路双平衡调节法,较好地解决了硫化铅温漂问题。
A new type of medium- temperature radiation thermometer based on silica fibers for light transmission and on PbS for photosensing is introduced in this pater. A 1 ℃ change can be measured at 200℃- A new practical method of double balance in bridge is presented. This method solves the problem of the temperature drift of PbS well.
