红外热像仪测温精度校准装置的建立及校准能力验证

Building and Proficiency Testing of Calibration Device for Temperature Measurement Accuracy of Thermal Imager

红外热像仪广泛应用于质量控制、安全检测等领域,为保证其测温的准确可靠,建立了红外热像仪测温精度校准装置,并对该校准装置进行了重复性试验、稳定性考核以及测量不确定度评定,通过采用传递比较法验证了该校准装置校准结果的可信度和测量不确定度的合理性,从而验证了该校准装置的校准能力,即可以开展相应等级的红外热像仪的测温精度校准工作。

Thermal imager is widely used in quality control, security detection and other fields. In order to ensure the accuracy and reliability of the temperature measurement, the calibration device for temperature measurement accuracy of thermal imager is built, and the repeatability test, stability assessment and measurement uncertainty evaluation of the calibration device are conducted. The reliability of calibration results and the rationality of measurement uncertainty are verified by using transfer comparison method, and thus the calibration capability of the calibration device is verified, which make it can be carried out the temperature measurement accuracy calibration of the appropriate level of thermal imager.
