用于热电偶动态校准系统的比色测温装置研究
Research on a colorimetric temperature measurement device for thermocouple dynamic calibration system
摘要
Abstract
To overcome the limitation that monochromatic infrared thermometry in laser-based thermocouple dynamic calibra-tion systems is susceptible to surface emissivity and requires pre-calibration for different thermocouples,a colorimetric tem-perature measurement device for thermocouple dynamic calibration systems is designed.The principle of dual-wavelength ra-diation ratio thermometry is described,and the optimal operating wavelengths of 1 483 nm and 1 600 nm together with the cor-responding filter bandwidths are determined through optimization.Static calibration and dynamic response experiments are car-ried out.Experimental results show that the relative measurement error of the device is below 1%for temperatures above 600℃,and the response time is less than 2 μs,satisfying the requirements for transient temperature measurement.The device is applied to the thermocouple dynamic calibration system,and the excitation temperature evolution on the thermocouple sur-face under laser heating is successfully obtained,validating its effectiveness and reliability in practical calibration scenarios.关键词
