Understand the principle and application scope of infrared thermometer
Infrared thermometers are widely used in power systems, mainly for remote measurement of the temperature of transmission and transformation lines and electrical equipment joints in substations. They can also be used for non-contact measurement of the temperature of various object surfaces 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: handheld infrared thermometers and online infrared thermometers. Remote infrared thermometer is a temperature measuring instrument that can measure the temperature of small targets at a distance.
The principle of a handheld infrared thermometer is to convert the radiation energy of the infrared 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. Handheld infrared thermometers are convenient and widely used 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 factors.
Online infrared thermometer: an effective tool for detecting and diagnosing electronic equipment faults. There are various types of fixed infrared thermometers, and different series play important roles 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 industry, paper and packaging industry, various kiln temperature measurement applications, and chemical industry to measure the temperature of instruments and meters, in order to detect the operating status of instruments and ensure their normal operation.
