Classification of non-contact infrared thermometers and how infrared works
Non-contact infrared thermometer, including portable, online and scanning three series, with a variety of options and computer software, each series has a variety of models and specifications. In different specifications of the various models of thermometer, the correct choice of infrared thermometer model is very important for users of infrared detection technology is the "Ninth Five-Year Plan" national scientific and technological achievements of the key promotional projects, infrared detection is a kind of on-line monitoring (non-stop) type of high-tech detection technology, which combines photoelectric imaging technology, computer technology, image processing technology, through the reception of infrared emitted by the object to be a key promotional project. It combines photoelectric imaging technology, computer technology, image processing technology in one, through the reception of infrared rays emitted by the object (infrared radiation), the thermal image will be displayed on the fluorescent screen, so as to accurately determine the temperature distribution of the surface of the object, has the advantages of accurate, real-time, fast and so on. Any object due to its own molecular movement, constantly radiating infrared thermal energy, thus forming a certain temperature field on the surface of the object, commonly known as "thermal image". Infrared diagnostic technology is through the absorption of this infrared radiation energy, measured the temperature of the surface of the equipment and the distribution of the temperature field, so as to determine the heat of the equipment. The application of infrared diagnostic technology test equipment is more, such as infrared thermometer, infrared thermal TV, infrared thermal imaging camera and so on. Like infrared thermal TV, infrared thermal imaging equipment such as the use of thermal imaging technology will not be able to see the "thermal image" into a visible image, so that the test effect is intuitive, high sensitivity, can detect subtle changes in the thermal state of the equipment, accurately reflecting the internal and external equipment, the heating situation, high reliability, very effective in the discovery of hidden equipment problems.
Can the alarm threshold value of the pyrometer be set and what is the trigger result?
Alarm reminder of the temperature measurement system, you need to set an alarm threshold, the size of the trigger value can be set, triggered, you can call the software built-in sound prompts, or can be recorded on-site sound as a reminder; can also be displayed in the operating terminal in the state of the alarm captured in the picture of the suspected heat personnel, and saved in the appropriate file directory, so as to later check; the specific operation of its software settings, such as the description of the specifications.
False alarms caused by common problems.
Temperature measurement system in actual use, temperature measurement system because there is no reasonable temperature measurement area, by the environment, such as: air conditioning blowing, direct sunlight, mirror reflection, etc., which may lead to temperature jumps and alarms; or in the delineation of the area of detection, the background of the person holding a cigarette butt, hot water cups, other hot objects, heat objects, etc., which may lead to alarms; the actual use of the false alarms must be aware of the investigation of this type of problem.
