Classification of non-contact infrared thermometers and the principle of infrared temperature measurement
Non-contact infrared thermometers include three series of portable, on-line and scanning, and are equipped with various options and computer software, and each series has various models and specifications. Among the various models of thermometers with different specifications, it is very important for users to choose the correct model of infrared thermometer. Infrared detection technology is a key promotion project of national scientific and technological achievements in the "Ninth Five-Year Plan". Non-stop) high-tech detection technology, which integrates photoelectric imaging technology, computer technology, and image processing technology, and displays its thermal image on the fluorescent screen by receiving infrared rays (infrared radiation) emitted by objects, thereby accurately judging the surface of the object. The temperature distribution has the advantages of accuracy, real-time, and rapidity. Due to the movement of its own molecules, any object continuously radiates infrared heat energy outward, 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 to measure the temperature of the equipment surface and the distribution of the temperature field, so as to judge the heating condition of the equipment. There are many test equipments that apply infrared diagnosis technology, such as infrared thermometer, infrared thermal TV, infrared thermal imager and so on. 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, high sensitivity, and able to detect subtle changes in the thermal state of the equipment and accurately reflect The internal and external heating conditions of the equipment have high reliability and are very effective in discovering hidden dangers of equipment.
