Infrared thermometer gun components and working principle
Infrared thermometer detection is an online monitoring (non-power-off) high-tech detection technology. It integrates photoelectric imaging technology, computer technology, and image processing technology. It receives the infrared rays (infrared radiation) emitted by objects and records their thermal images. It is displayed on the fluorescent screen to accurately judge the temperature distribution on the surface of the object, which has the advantages of accuracy, real-time and speed. Any object constantly radiates infrared heat energy due to the movement of its own molecules, thus forming a certain temperature field on the surface of the object, commonly known as "thermal image". Infrared diagnostic technology absorbs this infrared radiation energy and measures the temperature and temperature field distribution on the surface of the equipment to determine the heating condition of the equipment.
At present, there are many test equipments that apply infrared diagnostic technology, such as infrared thermometer guns, infrared thermal TVs, infrared thermal imaging cameras, etc. Equipment such as infrared thermal TVs and infrared thermal imaging cameras use thermal imaging technology to convert this invisible "thermal image" into a visible light image, making the test effect intuitive and highly sensitive. It can detect subtle thermal state changes of the equipment and accurately reflect The heating conditions inside and outside the equipment are highly reliable and very effective in discovering hidden dangers in the equipment.
Infrared temperature gun diagnostic technology can reliably predict early fault defects and insulation performance of electrical equipment, improving the preventive test maintenance of traditional electrical equipment to predictive maintenance. This is also the development direction of modern power enterprises. Especially the current development of large units and ultra-high voltage has put forward increasingly higher requirements for the reliable operation of the power system, which is related to the stability of the power grid. With the continuous development and maturity of modern science and technology, the use of infrared status monitoring and diagnosis technology has the characteristics of long-distance, no contact, no sampling, no disintegration, and is accurate, fast, and intuitive to monitor and diagnose electrical equipment online in real time. Most faults (can cover the detection of various faults of almost all electrical equipment). It has attracted much attention from the power industry at home and abroad (an advanced state-of-the-art maintenance system that was widely used in foreign countries in the late 1970s) and has developed rapidly. The application of infrared detection technology is of great significance to improving the reliability and effectiveness of electrical equipment, improving operating economic benefits, and reducing maintenance costs. It is a good means currently widely promoted in the field of predictive maintenance.
With the continuous development of technology, the best designs and new developments of infrared thermometer guns have provided users with various functional and multi-purpose instruments, expanding their choices. Other options include ease of use, repair and calibration capabilities, and price. When selecting a temperature measuring gun model, you should first determine the measurement requirements, such as the temperature of the target to be measured, the size of the target to be measured, the measurement distance, the material of the target to be measured, the environment where the target is located, response speed, measurement accuracy, whether to use a portable or online type, etc. ; Comparing various existing models of thermometers, select the instrument model that can meet the above requirements; select the best combination in terms of performance, function and price among many models that can meet the above requirements.
