The general principle and application of infrared thermometer
The temperature measurement of the infrared thermometer is based on the theory of Planck's radiation law, and the temperature of the measured target is determined by measuring the infrared radiation energy of the measured target and calibrated by the black body. The infrared thermometer has the characteristics of non-contact measurement, fast response speed, and does not disturb the temperature distribution field of the measured target. For the temperature measurement of some targets that cannot be measured by contact, moving targets, and targets whose temperature changes rapidly, infrared thermometers have their unique effects. It provides a new measurement method for the development of modern temperature measurement technology.
The elements of selecting an infrared thermometer: working principle, technical indicators, environmental working conditions, operation and maintenance, etc.
The components of the infrared thermometer: optical system, photodetector, signal amplifier and signal processing, display output, etc.
Application field of infrared thermometer
Compared with traditional temperature measuring equipment, the infrared tester has the advantages of convenience, safety and accuracy. Because there are so many advantages, the application range of infrared thermometer is very wide, as follows:
1 steel
The overall temperature of the regenerator and the efficiency of the heater can be continuously measured using an infrared thermometer. Measure the temperature on both sides of the plate to determine if the heating is even. Improve product quality
Two glass industry
Test the temperature of the furnace to ensure that the temperature of the glass is consistent from edge to edge and that the glass surface is flat. Thus: increase product yield, improve process control, improve product consistency, reduce downtime
Three plastic industry
Blown film pressing: precise temperature test to ensure uniform tensile strength and thickness of plastic Lamination and embossing treatment: use infrared thermometer to monitor film layer temperature and control heater
Four heating ventilation and cooling
Using infrared thermometers: scan room temperatures, check duct temperatures, test boiler temperatures and evaluate boiler performance, monitor supply and return air circuits
Five supermarkets or food processing enterprises
Because the storage temperature of refrigerated food is generally below 4.4°C, if it exceeds this range, it may deteriorate. So you can use the infrared thermometer to check it conveniently and quickly
Other applications include: grain processing, food processing, aquatic product processing, alcoholic beverage production enterprises, inspection and quarantine departments, etc.
