Infrared thermometer is a kind of temperature measuring instrument which adopts infrared ray as the principle, this kind of temperature measuring instrument can measure the temperature through the length of infrared ray. Infrared thermometer belongs to a kind of measuring instrument, this instrument can realize the near distance measurement and long distance measurement, it is a kind of temperature measuring instrument which can be used in various environments. There are many types of infrared thermometer, do you know what types of infrared thermometer? The following editorial to introduce you to the types of infrared thermometer and working principle.
1, infrared temperature measurement instrument types
Infrared temperature measurement instruments are mainly three types: infrared camera, infrared thermal TV, infrared thermometer (point temperature instrument). 60 years China successfully developed the first infrared thermometer, the early eighties after the production of small targets, long-distance, suitable for the characteristics of the electric production of the measurement of temperature Instruments, such as Xikuang IRT-1200D type, HCW-III type, HCW-V type; YHCW-9400 type; WHD4015 type (double aiming, target D?40mm, up to 15?m), WFHX330 type (optical aiming, target D?50?mm, up to 30?m). U.S. production of PM-20, 30, 40, 50, HAS-201 pyrometer; Sweden AGA TPT20, 30, 40, 50, etc. are also widely used. DL-500?E can be applied to 110 ~ 500?kV substation equipment, the image is clear, accurate temperature. Infrared camera, mainly Japan TVS-2000, TVS-100, the United States PM-250, Sweden AGA-?THV510, 550, 570. domestic infrared thermal imaging camera in Kunming successfully developed and localized.
2, infrared thermometer working principle
Understanding the working principle of infrared thermometer, technical specifications, environmental working conditions and operation and maintenance is the basis for users to correctly select and use the infrared thermometer. Optical system convergence of its field of view of the target infrared radiation energy, the size of the field of view by the thermometer's optical parts as well as the location of the decision. The infrared energy is focused on the photodetector and converted into a corresponding electrical signal. This signal is converted into a temperature value for the target by an amplifier and signal processing circuitry, corrected for the target emissivity and according to an algorithm within the instrument. In addition, the environmental conditions in which the target and the pyrometer are located, such as temperature, atmosphere, pollution and interference, should also be considered in terms of their impact on the performance indicators and correction methods.
All objects with temperatures above absolute zero are constantly emitting infrared radiation energy into the surrounding space. The size of the object's infrared radiation energy and its distribution by wavelength - and its surface temperature has a very close relationship. Therefore, through the measurement of the infrared energy radiated by the object itself, it will be able to accurately determine its surface temperature, which is based on the objective basis of infrared radiation temperature measurement.
The above is the type of infrared thermometer and the principle of operation of the introduction, we now know what the principle of infrared thermometer? Infrared thermometer is in the early 80's when the domestic production of manufacturing, is a kind of store can also be applied to the temperature measurement instruments, with the development and progress of the times, now the infrared thermometer is also commonly used in our lives. The working principle of infrared thermometer is very simple, mainly to the optical system as the main principle, the use of infrared radiation energy, we also need to pay attention to radiation when using infrared thermometer.
