Understanding of the principles and application areas of infrared thermometers
Infrared thermometers are widely used in power systems. They are mainly used for long-distance measurement of the temperature of power transmission lines and electrical equipment joints in substations. They can also be used in other industries to non-contactly measure the temperature of various object surfaces.
The temperature measurement principle of the infrared thermometer is to convert the infrared radiation energy emitted by an object (such as molten steel) into an electrical signal. The size of the infrared radiation energy corresponds to the temperature of the object (such as molten steel) itself, and is converted into an electrical signal according to the size. , the temperature of an object (such as molten steel) can be determined.
There are two types of infrared thermometers: one is a handheld infrared thermometer, and the other is an online infrared thermometer. A long-range infrared thermometer is a temperature measuring instrument that can measure the temperature of small targets at long distances.
The principle of the handheld infrared thermometer is: the principle used is to convert the radiant energy of the infrared ray emitted by the object into an electrical signal. The size of the infrared radiant energy corresponds to the temperature of the object itself. According to the size of the converted electrical signal, it can be determined The temperature of an object (such as molten steel). The handheld infrared thermometer consists of an optical system, photodetector, signal amplifier, signal processing, display output and other parts. Handheld infrared thermometers are convenient, accurate and safe, and are widely used in medical and equipment fault diagnosis. When purchasing an infrared thermometer, you should pay attention to factors such as performance indicators (such as temperature range, spot size, operating wavelength, measurement accuracy, response time, etc.), ease of use, maintenance and calibration performance, and price.
Online infrared thermometer: an effective tool for detecting and diagnosing faults in electronic equipment. There are many varieties of fixed infrared thermometers, and different series play an important role in their respective industries. The main performance indicators of fixed infrared thermometers include spectral response, response time, repeatability and emissivity. Fixed infrared thermometers are used in the glass and ceramic industries, papermaking and packaging industries, various kiln temperature measurement applications, and the chemical industry to measure the temperature of instruments and meters to detect the operating status of the instruments and ensure the normal operation of the instrument. run.
