What is the temperature measurement principle of the two color pyrometer?

(Summary description)The principle of temperature measurement of two color pyrometer: The two color pyrometer determines the temperature by the ratio of the infrared radiation energy of the two bands of adjacent channels. The ratio changes linearly with temperature and depends on the performance of the detector.

Information

Two color pyrometer, also called colorimetric thermometer, its principle is to use the ratio of the infrared radiation energy of two adjacent bands to determine the temperature. Two color pyrometer has a wide range of applications in smelting, casting, steel rolling, forging, powder metallurgy, chemical industry, glass processing, ceramics, intermediate frequency induction heating, welding and other industries.

two color pyrometer

The principle of temperature measurement of two color pyrometer: The two color pyrometer determines the temperature by the ratio of the infrared radiation energy of the two bands of adjacent channels. The ratio changes linearly with temperature and depends on the performance of the detector.

The two color pyrometer can eliminate the influence of water vapor and dust on the size change, partial occlusion, emissivity change of the detection target, etc. It is not necessary to correct the two-color coefficient when measuring most gray body materials. The two color pyrometer can also measure a certain The highest temperature of the area. The two color pyrometer can overcome the influence of serious water vapor, dust, changes in the size of the detection target, partial obscuration, changes in emissivity and other factors. Even if the detection signal is attenuated by 95%, its measurement effect will not be affected. The design of the combination of software and hardware can realize the reliable detection of signals with a dynamic range of one million times, and meet the user's requirements for instrument accuracy and resolution.

The above is the temperature measurement principle of the two color pyrometer introduced to you, I hope it will be helpful to you!
