How do we use infrared thermometers to detect in our daily lives?
Infrared thermometer detection is an online monitoring (non-stop) type of high-tech detection technology, which combines photoelectric imaging technology, computer technology, image processing technology in one, through the reception of infrared radiation (infrared radiation) emitted by the object, the thermal image will be displayed on a fluorescent screen, so as to accurately determine the temperature distribution of the surface of the object, has the advantages of accurate, real-time, fast and so on. Any object due to its own molecular movement, constantly radiating infrared thermal energy, thus forming a certain temperature field on the surface of the object, commonly known as "thermal image". Infrared diagnostic technology is through the absorption of this infrared radiation energy, measured the temperature of the surface of the equipment and the distribution of the temperature field, so as to determine the heat of the equipment.
At present, the application of infrared diagnostic technology test equipment is more, such as infrared thermometer, infrared thermal TV, infrared thermal imaging camera and so on. Like infrared thermal TV, infrared thermal imaging equipment such as the use of thermal imaging technology will not be able to see the "thermal image" into a visible image, so that the test effect is intuitive, high sensitivity, can detect subtle changes in the thermal state of the equipment, accurately reflecting the internal and external equipment, the heating situation, high reliability, very effective in the discovery of hidden equipment problems.
Infrared thermometer Diagnostic technology for electrical equipment early failure defects and insulation performance to make reliable predictions, so that the traditional preventive testing and maintenance of electrical equipment to improve to the predictive state overhaul, which is the direction of the development of modern electric power enterprises. Especially now the development of large units, ultra-high voltage, the reliable operation of the power system, related to the stability of the power grid, put forward more and more high requirements. With the continuous development of modern science and technology maturity and increasing perfection, the use of infrared condition monitoring and diagnostic technology has a long-distance, non-contact, non-sampling, non-disassembly, but also accurate, fast, intuitive and other characteristics of real-time on-line monitoring and diagnosis of most of the faults of the electrical equipment (almost all electrical equipment can be covered by a variety of faults in the detection of all kinds of faults). It is highly valued by the power industry at home and abroad (an advanced state maintenance system commonly used in foreign countries in the late 1970s), and has been developing rapidly. The application of infrared detection technology to improve the reliability and effectiveness of electrical equipment, improve the economic efficiency of operation and reduce maintenance costs are of great significance. Is currently in the field of predictive maintenance in the general promotion of a very good means.
With the technology and continuous development, infrared thermometer Optimal design and new advances provide users with a variety of functions and multi-purpose instruments, expanding the choice. Other selection aspects such as ease of use, maintenance and calibration performance, and price. In the selection of pyrometer models should first determine the measurement requirements, such as the measured target temperature, the measured target size, measurement distance, the measured target material, the target environment, response speed, measurement accuracy, with portable or online and so on; in the existing various models of pyrometer comparison, selected to meet the above requirements of the instrument model; in the many models that can meet the above requirements to select the model in terms of performance, functionality In the many models that can meet the above requirements to select the performance, functionality and price of the * best match.
