本文介绍了采用硒化铅(PbSe)光敏电阻作检测元件制成的红外线辐射温度计,用其测量沸腾层硬微粒表面之温度,效果尚好。着重介绍了红外线接受变换器结构及电子测温线路原理。
In this paper, an infrared radiation thermometer made of lead selenide (PbSe) photosensitive resistor is introduced to measure the surface temperature of the hard particle of the boiling layer, and the effect is still good. Emphasis on the introduction of infrared receiver structure and electronic temperature measurement circuit principle.
