摘要
日本CHINO公司生产的IR-RST系列标准辐射温度计由于没有设计温度显示装置,无法实时显示温度,针对此类型温度计设计了一款专用的电压测量和温度显示,同时可提供24 V直流电压的电测显示仪表。利用高等级的电压源和数字电压表,修正了本专用数字表的误差系数,并考核了稳定性,得到其最大相对误差不超过0. 03%。与一款名义波长为0. 65μm的IR-RST辐射温度计配合使用,通过TG HT-9500型高温炉对其组合进行内插分度,实验结果证实分度后校准准确度优于0. 03%,1300℃时系统测量结果的扩展不确定度为0. 62℃。
The IR-RST standard radiation thermometers manufactured by CHINO Company,Limited,Japan,which can not display the temperature in real-time because the display unit hadn’t been designed. Therefore,an electrical measurement display device was designed which can measure the voltage,display the temperature and supply 24 V DC voltage for this kind of infrared radiation thermometer. Calibrated a against high-level voltage power source and a voltmeter,the correction coefficients of the display instrument were got,the stabilitywas evaluated as well,the maximum relative error of voltage measurement can be achieved with in 0. 03%. Assembled with a 0. 65 μm IR-RST radiation thermometer,it was calibrated against with a TG HT-9500 type high-temperature furnace as the source,the accuracy was better than 0. 03%confirmed by the experimental results,and the extended uncertainty of the calibration system was 0. 62 ℃ at 1 300 ℃.
