本文介绍了一种中温黑体炉配用的简单适用的温度数字显示装置。它采用铂电阻作感温元件,非线性R-V转换电路进行线性化,三重积分型A/D转换,以四位数字进行温度显示。测温范围为73K到1000K,分辨率0.1K,精度为0.1％,并且附有炉温上限的设定和超温报警电路。黑体炉系统加装此显示装置后,提高了测温精度,简化了系统,方便了使用。
This paper introduces a simple and suitable temperature digital display device for medium temperature blackbody furnace. It uses platinum resistance as temperature sensing element, nonlinear R-V conversion circuit for linearization, triple integral A / D conversion, with four-digit temperature display. Temperature range of 73K to 1000K, resolution 0.1K, accuracy of 0.1%, and with the temperature limit set and over-temperature alarm circuit. After installing this display device, the blackbody furnace system improves the temperature measurement accuracy, simplifies the system and facilitates the use.
