Understand the principle and usage range of infrared thermometer
Infrared thermometers are widely used in power systems, mainly for long-distance measurement of the temperature of electrical equipment joints in transmission and transformation lines and substations. They can also be used for non-contact measurement of the surface temperature of various objects in other industries.
The temperature measurement principle of an infrared thermometer is to convert the radiation energy emitted by an object (such as molten steel) into an electrical signal. The magnitude of the infrared radiation energy corresponds to the temperature of the object (such as molten steel) itself. Based on the magnitude of the converted electrical signal, the temperature of the 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. Remote infrared thermometer is a temperature measuring instrument that can measure the temperature of small targets at a long distance.
The principle of a handheld infrared thermometer is to convert the radiation energy emitted by an object into an electrical signal. The magnitude of the infrared radiation energy corresponds to the temperature of the object itself. Based on the magnitude of the converted electrical signal, the temperature of the object (such as molten steel) can be determined. The handheld infrared thermometer consists of an optical system, a photodetector, a signal amplifier, signal processing, display output, and other components. The handheld infrared thermometer is convenient, military, and safe, and has a wide range of applications in medical and equipment fault diagnosis. When choosing an infrared thermometer, attention should be paid to performance indicators (such as temperature range, spot size, working wavelength, measurement accuracy, response time, etc.), ease of use, maintenance and calibration performance, and price.
Online infrared thermometer: It is an effective tool for detecting and diagnosing electronic equipment faults. There are various types of fixed infrared thermometers, and different series play an important role in their respective industries. The main performance indicators of a fixed infrared thermometer include spectral response, response time, repeatability, and emissivity. Fixed infrared thermometers are used in glass and ceramic industries, paper and packaging industries, various kiln temperature measurement applications, and chemical industries to measure the temperature of instruments and meters, thereby detecting the operating status of instruments and ensuring their normal operation.
