What is the difference between an infrared thermometer and a thermometer gun?
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 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 a thermal image of the temperature gradient 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.
