Based on the technique of radiate temperature measurement, the author designs a circuit of prismatic decomposition colorimetric radiate temperature measuring. A high resolution A/D converter and measurement range switch technology are adopted to resolve the problem that it has lower radiation power and lower signal sensitivity in the low-temperature stage, while higher signal amplitude and higher need of dynamic range in the high-temperature stage. The technique of the Black Body Furnace demarcates, digital calibration and the quartic curve fitting are applied to correct the sensor and improve its measurement precision.
