Two-color infrared thermometer – unmatched
“Two-color infrared thermometer” is an infrared thermometer. The measurement of objects in two different spectral range of infrared radiation emitted by the brightness ratio of the two inferred radiance temperature of a body, called the two-color thermometer. In fact, the color brightness and color thermometer is not the meaning, and brightness Thermometer (Optical Pyrometer) compared to two in principle is different. This “color” means should be infrared wavelength or spectrum, is the “double IR thermometer.”
Color and color infrared thermometer infrared thermometer compared with unparalleled advantages. In a small metal enclosure filled with a lot of optics, optoelectronics and microelectronics devices with monochrome and color composition of the non-contact temperature measurement function infrared thermometer.
Principles of two-color infrared thermometer
Two-color thermometer is based on the work of the following principles: two infrared wavelengths in selected and a certain bandwidth, the ratio of their radiation energy as the temperature changes. Bandwidth is very narrow use of two different color filters, collection of two similar radiation energy within the band and put them into electrical signals and then compare this ratio to determine the final temperature of the measured object, so it can basically target material emissivity adjustment to eliminate the inconvenience of using two-color thermometer temperature higher sensitivity, with the goal of true temperature deviations less absorbed by the object during the test distance and the impact is also smaller in the high temperature range of use results were better.

The characteristics and performance of color thermometer

1. The basic goal of eliminating the measured emission rate on the temperature measurement results.
2. The measured target is very small, not full field of view, measuring the presence of smoke on the road, dust and so will not have significant effect on the measurement results.
3. Two-color pyrometer operating temperature is mainly in the high temperature zone.
4. High precision, fast response, distance coefficient is high.

Application of two-color infrared thermometer
Where the measured temperature is higher, difficult to determine the emission rate, the target is too small field of view can not be filled, there is the line attenuation measurement of radiation energy material, where it can be resolved by two-color infrared thermometer temperature measurement accuracy problem, and monochrome Thermometer difficult to resolve the issue.
Application of two-color infrared thermometer wide range of areas, particularly in the steel industry, metal heat treatment, metal processing and casting and so on.
Under the following conditions, two-color infrared thermometer is the preferred program.
(1) present in the environment as dust, smoke and particles resulting from the decay of energy;
(2) observing the lens dirty windows and equipment;
(3) Instrument blocked or covered the local scene;
(4) target small field of view instruments can not be filled;
(5) The target is in motion or vibration;
(6) measurement channel bend, narrow, obstructed;
(7) the measurement of liquid metal;
For example: steel, hot metal, copper water, aluminum, water, steel processing, wire processing, filament production, glass industry, induction welding, metal heat treatment, foundry, furnace and kiln, induction heating, plumbing annealing
