Several Factors Affecting the Measurement Accuracy of Non-contact Infrared Thermometer
1. Emissivity: The emissivity of the surface of a general object is 0.95, and the emissivity of other materials can be found from the published emissivity table.
2. Field of view: the ratio of the distance from the infrared thermometer to the measured object and the measured spot size.
3. Object distance ratio: ensure that the area of the object to be measured is larger than the spot size measured by the infrared thermometer. The smaller the area of the object to be measured, the closer it should be to the word.
Introduction to related applications of infrared thermometers
1. In terms of scientific research, due to the outstanding advantages of infrared thermometers, it can provide temperature measurement means under special test conditions and has a wide range of applications.
2. In agriculture, the measurement of soil and plant surface temperature, the temperature measurement of grain and seed drying process, the temperature monitoring of agricultural by-products such as tobacco leaves and tea processing process, the monitoring of Chinese herbal medicine drying and pharmaceutical temperature monitoring.
3. In the chemical industry, chemical equipment works under high temperature and high pressure. It is very useful to monitor the heat distribution of the equipment, judge the working condition of the equipment, and detect the heat loss and heat leakage faults of the heat channel interface.
4. In the construction industry, infrared thermometers are used to detect the thermal distribution of building walls, floors, and roofs to determine its insulation, hidden dangers of cracks, and the location of defects. Determine the management of heat consumption in factories and buildings.
5. Infrared thermometers used in the iron and steel industry account for more than half of the total.
Measuring and controlling temperature during steelmaking, rolling, casting and quenching plays an important role in improving product quality. The monitoring of thermal failures of furnace walls and mechanical equipment provides the basis for extending service life and ensuring safety.
6. In the power and electric power industry, it is used to detect abnormal temperatures of power equipment, power distribution equipment, cables, electrical connectors, etc. under operating and electrified conditions. Infrared thermometers provide a certain guarantee for the safe operation of equipment.
7. In mechanical processing, infrared thermometers measure and control the temperature of heat-treated parts, which plays a key role in product quality.
