Explanation of the General Principles and Applications of Infrared Thermometers

 

The temperature measurement of an infrared thermometer is based on Planck's radiation law. By measuring the infrared radiation energy of the measured target and calibrating it with a blackbody, the temperature of the measured target is determined. Infrared thermometers have the characteristics of non-contact measurement, fast response speed, and no disturbance to the temperature distribution field of the measured target. For temperature measurement of targets that cannot be measured by contact, moving targets, and targets with rapid temperature changes, infrared thermometers have their unique effects. It provides a new measurement method for the development of modern temperature measurement technology.


Elements for selecting an infrared thermometer: working principle, technical specifications, environmental working conditions, and operation and maintenance, etc


The components of an infrared thermometer include optical system, photodetector, signal amplifier and processing, display output, etc


Application fields of infrared thermometers
A steel
The use of an infrared thermometer can continuously measure the temperature of the entire reheater and the efficiency of the heater. Measure the temperature on both sides of the steel plate to determine if the heating is uniform. Improve product quality


Glass industry
Test the temperature of the furnace to ensure consistent temperature from edge to edge of the glass and a flat surface of the glass. Thus: improving product yield, enhancing process control, improving product consistency, and reducing downtime


Three plastic industries
Blow molded film pressing: Temperature testing can ensure the tensile strength and uniform thickness of the plastic. Stacking and embossing treatment: Use an infrared thermometer to monitor the film temperature and control the heater

Heating, Ventilation, and Refrigeration
Using an infrared thermometer: scanning room temperature, checking pipeline temperature, testing boiler temperature, evaluating boiler performance, monitoring air supply and return circuits
