What is the temperature measuring principle of infrared thermal imager?

Any object in nature whose temperature is higher than absolute zero (-273. 15℃) can radiate infrared energy. The physical essence of infrared radiation is thermal radiation and electromagnetic wave.

Infrared thermal imager converts infrared thermal radiation into corresponding electrical signals, and after amplification and video processing, a video image that can be observed by naked eyes is formed. Generally speaking, it is to turn invisible infrared radiation into visible thermal image, reflecting the temperature distribution on the target surface.

The thermal image corresponds to the thermal distribution field on the surface of the object. Different colors on the thermal image represent different temperatures of the measured object. By looking at the thermal image, we can intuitively observe the overall temperature distribution of the measured target, study the heat of the target and judge the next work.

Compared with the equipment using visible light, infrared thermal imaging technology is passive non-contact detection and identification of targets, so it has good concealment and is not easy to be found, thus making the operator of infrared thermal imager safer and more effective.

In addition, the monitored target can be clearly observed in the dark night, or in the harsh environment with dense clouds such as rain and snow. It is precisely because of this feature that the infrared thermal imager can truly monitor for 24 hours.

With the continuous development of infrared thermal imaging technology and the reduction of cost, thermal imaging equipment has been widely used in electric power, industry, agriculture, security, medical care, fire protection, archaeology, transportation, geology and other civil fields.

Many thermal camera brands have rich application cases. For example, Gao De Zhi Gan can provide infrared thermal imaging products and solutions with strong performance, good experience and excellent service for all walks of life, and has rich application cases and user feedback in dozens of key industries.
