Technical Characteristics and Usage Methods of Infrared Thermometers
1. Overview
Infrared temperature measurement technology plays an important role in product quality control and monitoring, online fault diagnosis and safety protection of equipment, and energy conservation in the production process. In the past 20 years, non-contact infrared thermometers have developed rapidly in technology, with continuously improved performance, enhanced functions, an increasing variety of products, and an expanding range of applications. Their market share has been increasing year by year. Compared to contact based temperature measurement methods, infrared temperature measurement has the advantages of fast response time, non-contact, long use and service life. Non contact infrared thermometers include three series: portable, online, and scanning, and are equipped with various options and computer software. Each series also has various models and specifications. Choosing the correct infrared thermometer model is crucial for users among various types of thermometers with different specifications.
Infrared detection technology is a key promotion project of national scientific and technological achievements during the Ninth Five Year Plan period. Infrared detection is an online monitoring (uninterrupted) high-tech detection technology that integrates optoelectronic imaging technology, computer technology, and image processing technology. By receiving the infrared radiation emitted by an object and displaying its thermal image on a fluorescent screen, it can accurately determine the temperature distribution on the surface of the object. It has the advantages of accuracy, real-time, and speed. Any object continuously radiates infrared thermal energy outward due to the motion of its own molecules, thereby forming a certain temperature field on the surface of the object, commonly known as a "thermal image". Infrared diagnostic technology measures the temperature and temperature field distribution on the surface of equipment by absorbing this infrared radiation energy, in order to determine the heating condition of the equipment. At present, there are many testing equipment that apply infrared diagnostic technology, such as infrared thermometers, infrared thermal televisions, infrared thermal imagers, and so on. Devices such as infrared thermal TVs and infrared thermal imagers use thermal imaging technology to transform invisible "thermal images" into visible light images, making the testing effect intuitive, highly sensitive, and able to detect subtle changes in the thermal state of the equipment, accurately reflecting the internal and external heating conditions of the equipment. It has high reliability and is very effective in discovering hidden dangers in the equipment.
