一、概述我国最早的辐射测温仪是五十年代开始生产的WFT-202型辐射高温计(400～2000℃分段)和光学高温计(800～3000℃分段)。测温精度前者取决于由热偶丝组成的热电堆探测器,后者取决于人眼的亮度分辨能力和标准灯炮的稳定性。由于这两种仪器结构简单、可靠性高和工艺成熟价格便宜,因而获得了广泛的应用,至今仍是人们经常使用的非接触测温工具。六十年代我国出现了以硫化铅红外探测器
First, an overview China’s earliest radiation thermometer is the WFT-202 radiation pyrometer (400 ~ 2000 ℃ segment) and optical pyrometer (800 ~ 3000 ℃ segment) that began production in the 1950s. The former depends on the thermocouple thermocouple thermocouple wire detector composition, the latter depends on the brightness of the human eye and the resolution of standard lamp stability. Because of their simple structure, high reliability and low price, the two instruments are widely used and are still the non-contact temperature measuring tools that people often use. Sixty time our country appeared with lead sulfide infrared detectors
