Recognize the purpose and range of application for infrared thermometers.
Infrared thermometers are widely used in power systems, mainly for long-distance measurement of the temperature of power transmission lines and substation electrical equipment joints, and can also be used for non-contact measurement of the surface temperature of various objects in other industries.
The temperature measurement principle of the infrared thermometer is to convert the radiant energy of the infrared rays emitted by the object (such as molten steel) into an electrical signal. The size of the infrared radiant energy corresponds to the temperature of the object (such as molten steel) itself. , 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-distance infrared thermometer is a temperature measuring instrument that can measure the temperature of a small target at a long distance.
The principle of the handheld infrared thermometer is: the principle used is to convert the radiant energy of the infrared rays emitted by the object into electrical signals. 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 is composed of optical system, photoelectric detector, signal amplifier, signal processing, display output and other parts. The handheld infrared thermometer is convenient and widely used in medical treatment 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, 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 failures. There are many varieties of fixed infrared thermometers, and different series play an important role in their respective applicable industries. The main performance indicators of fixed infrared thermometers are spectral response, response time, repeatability and emissivity. Fixed infrared thermometers are used in glass and ceramic industries, papermaking and packaging industries, various kiln temperature measurement applications, and chemical industry to measure the temperature of instruments and meters, so as to detect the operating status of instruments and meters and ensure the normal operation of an instrument. run.
