What is the difference between infrared thermometers and thermoguns?
Infrared thermometer technology plays an important role in product quality control and monitoring, equipment online fault diagnosis and safety protection, and energy conservation during the production process. In the past 20 years, non-contact infrared thermometers have developed rapidly in technology, their performance has been continuously improved, their functions have been continuously enhanced, their varieties have continued to increase, their scope of application has also continued to expand, and their market share has increased year by year. Compared with contact temperature measurement methods, infrared temperature measurement has the advantages of fast response time, non-contact, safe use and long service life. Non-contact infrared thermometers include three series: portable, online and scanning, and are equipped with various options and computer software. Each series has various models and specifications. Among various models of thermometers with different specifications, it is very important for users to correctly select the model of infrared thermometer.
Infrared detection technology is a key promotion project of national scientific and technological achievements in the "Ninth Five-Year Plan". The temperature measuring gun 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 the object display its thermal image on the fluorescent screen, thereby accurately judging 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. Currently, there are many test equipments that apply infrared diagnostic technology, such as infrared thermometers, 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 diagnostic technology can reliably predict early faults, defects and insulation performance of electrical equipment, improving the preventive test maintenance of traditional electrical equipment (preventive testing was a standard introduced in the former Soviet Union in the 1950s) to predictive state maintenance, which is also the standard for modern electric power equipment. The direction of enterprise development. 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 of temperature measuring guns 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, and it can also bring the level of maintenance and the health of the equipment to a higher level.
Infrared imaging detection technology can be used to conduct non-contact detection of running equipment, photograph the distribution of its temperature field, measure the temperature value of any part, and diagnose various external and internal faults based on this, which is real-time, telemetry, intuitive and quantitative. With advantages such as temperature measurement, it is very convenient and effective to detect operating equipment and live equipment in power plants, substations and transmission lines.
The method of using thermal imaging cameras to detect online electrical equipment is the infrared temperature recording method. Infrared temperature recording method is a new technology used in industry for non-destructive detection, testing equipment performance and understanding its operating status. Compared with traditional temperature measurement methods (such as thermocouples, wax sheets with different melting points, etc. placed on the surface or inside the body), thermal imaging cameras can detect the temperature of hot spots in real time, quantitatively, and online within a certain distance. , it can also draw the temperature gradient thermal image of the equipment during operation, and it is highly sensitive and free from electromagnetic field interference, making it easy to use on site. It can detect thermal faults in electrical equipment with a high resolution of 0.05°C in a wide range of -20°C to 2000°C, revealing such things as heating of wire joints or clamps, as well as local hot spots in electrical equipment.
Infrared diagnostic technology of live equipment is an emerging discipline. It is a comprehensive technology that utilizes the heating effect of charged equipment and uses special equipment to obtain infrared radiation information emitted from the surface of the equipment to determine the condition of the equipment and the nature of defects.
