Eight-wavelength pyrometer which can simultaneously measure the true temperature and spectral emissivity

Based on a new method for the data processing of the multispectral thermometry, a brand-new multiwavelength pyrometer is developed for simultaneously measuring the true temperature and spectral emissivity. Prism technique is used for splitting the radiation beam in the optical system, which can overcome the disadvantages of the traditional method with optical fibers for beam split and interference filters for effective wavelengths defined. SA68D22 module is used so that wireless data communication can be realized. Based on the new emissivity assumption presented here, the multi-wavelength pyrometer can be used for the true temperature and spectral emissivity measurement of the most engineering materials.
