真实温度的辐射测量
Radiation measurement for real temperature
摘要
Abstract
The equation of radiation temperature measurement is put forward, and the functional relationship between the object and the instrument is established. By analyzing the radiation temperature measurement model, the conditions to realize radiation measurement for the real temperature is found, that is, using the specific wavelength at the intersection point of the emissivity curve of the object and the instrument, the real temperature can be obtained by closed solution of the specific instrument temperature. Waveband radiation sensing and primary spectrum function clusters are two key technologies to obtain the real temperature. The former is to"cover"specific wavelength with uncertain numerical value, while the latter provides wavelength coordinate axis to identify specific wavelength with different numerical value. Taking tungsten as an example, the influence of the number of specific wavelengths on temperature solution is analyzed, and the error formula of temperature measurement by primary spectrum pyrometry is given.关键词
