What is thermal camera？

In specific applications, we can often see thermal cameras in the steel metallurgy industry and petrochemical industry. For example, when detecting the defects of the ladle refractory material, because the interior of the ladle is a refractory material, it is corroded by high temperature molten steel for a long time, and the thickness of the ladle wall may be reduced. Therefore, it is very easy to cause the leakage of the ladle.

By detecting the surface temperature of the ladle through the thermal camera, the thickness of the ladle wall can be reversed, so that corresponding maintenance measures can be taken to prevent accidents. We provide thermal camera, if you are interested in thermal camera, please contact us for more information.

Nowadays, science and technology are becoming more and more advanced. The emergence and application of various new technologies have made our daily work and life more convenient and efficient. Similarly, thermal camera has gradually faded its mysterious veil and began to enter the public In work and life, then, when we need to use the thermal camera in our work and life, how should we choose?

Thermal camera is an instrument that detects the surface temperature and distribution of objects, mainly related to temperature; temperature is invisible and intangible, but can be felt, while thermal camera can visualize temperature. It can also realize non-contact temperature measurement, and it can still detect the temperature distribution in the field of view in the dark night or heavy fog, and the response is very fast (milliseconds)...There are better applications in different occasions.

The principle of thermal camera is to use infrared detector and optical imaging objective lens to receive the infrared radiation energy of the measured target, and reflect the energy distribution pattern on the photosensitive element of the infrared detector to obtain infrared thermal image. This thermal image is similar to The heat distribution field on the surface of the object corresponds to it.

In layman's terms, a thermal imaging camera converts the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent different temperatures of the measured object.

(1) The temperature field on the surface of the object can be displayed intuitively. Thermal camera can measure the temperature of each point on the surface of the object and display it in image form.

(2) The temperature resolution is high, and the thermal camera can display the temperature values ​​of multiple points at the same time, so it can accurately distinguish small temperature differences.

(3) Data storage and computer processing can be carried out. The video signal output by thermal camera can be stored in digital memory or recorded with video tape, so that it can be maintained for a long time and can be processed by computer.
