The infrared thermal imaging camera accurately quantifies the actual detected heat and images the entire target object in real time in the form of a surface, so it can accurately identify the suspected fault area that is generating heat. The operator can initially judge the heating situation and fault location through the image color and hot spot tracking display function displayed on the screen, and conduct rigorous analysis at the same time, thus demonstrating high efficiency and high accuracy in confirming the problem.
Working principle
A thermal imaging camera converts the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the thermal image represent different temperatures of the object being measured. By viewing the thermal image, you can observe the overall temperature distribution of the target being measured, study the heating condition of the target, and make judgments about the next step. Modern thermal imaging cameras work by using optoelectronic devices to detect and measure radiation and establish a correlation between radiation and surface temperature. All objects above absolute zero (-273°C) emit infrared radiation. The thermal imager uses an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector to obtain an infrared thermal image. This thermal image is consistent with the heat distribution field on the surface of the object. Corresponding.
Thermal Imaging Advantages
1. Since infrared thermal imaging technology is a passive, non-contact detection and identification of targets, it is well concealed and difficult to be discovered, making the operator of the infrared thermal imaging camera safer and more effective.
2. Infrared thermal imaging technology has strong detection ability and long range. Using infrared thermal imaging technology, observation can be carried out beyond the range of enemy defense weapons, and its effect range is long. Thermal imaging cameras that are handheld or mounted on small weapons can allow users to see the human body clearly at a distance of more than 800m; the range of aiming and shooting is 2~3km; the water surface can be observed up to 10km on a ship, and can be found on a helicopter at a height of 15km. The activities of individual soldiers on the ground can be used to detect crowds and moving vehicles on the ground on a 20km-high reconnaissance aircraft, and can analyze changes in seawater temperature to detect underwater submarines, etc.
3. Infrared thermal imaging technology can truly achieve 24-hour monitoring. Infrared radiation is the most widespread radiation in nature. The atmosphere, smoke, etc. can absorb visible light and near-infrared rays, but are transparent to infrared rays of 3~5μm and 8~14μm. These two bands are called the "atmosphere" of infrared rays. window". Therefore, using these two windows, you can clearly observe the target to be monitored in a completely dark night, or in a harsh environment such as rain or snow, with dense smoke and clouds. It is precisely because of this feature that infrared thermal imaging technology can truly achieve 24-hour monitoring.
4. Infrared thermal imaging technology can intuitively display the temperature field on the surface of an object without being affected by strong light, and can be monitored even when there are obstructions such as trees and grass. Infrared thermometers can only display the temperature value of a small area or point on the surface of an object, while infrared thermal imaging cameras can simultaneously measure the temperature of various points on the surface of an object, visually display the temperature field on the surface of the object, and display it in the form of an image. display. Since the infrared thermal imager detects the amount of infrared heat radiation energy of the target object, it does not halo or shut down like the low-light image intensifier when it is in a strong light environment, so it is not affected by strong light.
