在准确度方面,辐射测量校准远优于探头技术.所需要的量值正是实际上所测量的。关于辐射亮度对校准参量的关系,仅作了极少的假定,辐射测量技术还能够探测能引起误差的其它条件.但是,这种技术是非常复杂的,它要求有高级仪器、富于经验的工作人员以及大量的时间。因为具有辐射校准能力的设备甚少,所以黑体需要别处送检,而用户需停工等待一个月或更长时间.但是,当要求的误差低于±3℃时,辐射测量技术就是必要的。辐射测量校准能够得到的误差为在200℃时的±0.2℃到1000℃时的±0.5℃;发射率误差为±0.001。
Radiometric calibration is far superior to probe technology in terms of accuracy, and the exact amount needed is actually measured. With regard to the relationship between the radiance and the calibration parameters, only a few assumptions have been made, and the radiometric technique can detect other conditions that can cause errors, but this technique is very complex and requires sophisticated instrumentation Staff and a lot of time. Because there are very few devices with radiation calibration capability, the blackbody needs to be examined elsewhere, and the user has to wait a month or more for downtime, but radiometric techniques are necessary when the required error is less than ± 3 ° C. Radiation measurement calibration can be obtained by the error at 200 ℃ ± 0.2 ℃ to 1000 ℃ ± 0.5 ℃; Emissivity error of ± 0.001.
