Termometri infra-aħmar huma ħfief, kompatti, faċli biex jintużaw, u jkejlu b'mod affidabbli oġġetti sħan, perikolużi, jew diffiċli biex jintlaħqu mingħajr ma jikkontaminaw jew jagħmlu ħsara lill-oġġett li jkun qed jitkejjel. Termometri infra-aħmar jistgħu jieħdu diversi qari kull sekonda, filwaqt li t-termometri tal-kuntatt jieħdu diversi minuti biex ikejlu kull sekonda.
2. Kif jaħdem it-termometru infra-aħmar? Shenzhen Yuanhengtong Technology Co., Ltd.
Termometri infra-aħmar jirċievu enerġija infra-aħmar inviżibbli emessa minn diversi oġġetti nfushom. Ir-radjazzjoni infra-aħmar hija parti mill-ispettru elettromanjetiku, li jinkludi mewġ tar-radju, microwaves, dawl viżibbli, ultravjola, raġġi-R u raġġi-X. Infrared tinsab bejn dawl viżibbli u mewġ tar-radju. Il-wavelengths infra-aħmar huma komunement espressi f'mikroni, u l-firxa tal-wavelength hija 0.7 mikroni għal 1000 mikron. Fil-fatt, il-medda ta '0.7 mikroni sa 14-il mikron tintuża għal termometri infra-aħmar
3. Kif tiżgura l-preċiżjoni tal-kejl tat-temperatura tat-termometru infra-aħmar? Shenzhen Yuanhengtong Technology Co., Ltd.
The undisputed understanding of infrared technology and its principle is its temperature measurement. When the temperature is measured by an infrared thermometer, the infrared energy emitted by the measured object is converted into an electrical signal on the detector through the optical system of the infrared thermometer, and the temperature reading of the signal is displayed, and several of them determine the temperature measurement The most important factors are the emissivity, the field of view, the distance to the spot and the position of the spot. Emissivity, all objects reflect, transmit, and emit energy, and only the emitted energy gives an indication of the object's temperature. When an infrared thermometer measures surface temperature, the instrument receives all three types of energy. Therefore, all infrared thermometers must be tuned to read only emitted energy. Measurement errors are often caused by infrared energy reflected from other light sources. Some infrared thermometers can vary the emissivity, and emissivity values for various materials can be found in published emissivity tables. Other instruments were fixed with an emissivity preset of 0.95. This emissivity value is for the surface temperature of most organic materials, painted or oxidized surfaces, and is compensated by applying a tape or flat black paint to the surface being measured. When the tape or varnish reaches the same temperature as the base material, measure the temperature of the surface of the tape or varnish, which is its true temperature. The ratio of the distance to the spot. The optical system of the infrared thermometer collects energy from the circular measuring spot and focuses it on the detector. The optical resolution is defined as the ratio of the distance from the infrared thermometer to the object and the size of the spot to be measured (D :S). The larger the ratio, the better the resolution of the infrared thermometer and the smaller the measured spot size. Laser aiming, only to aid in aiming at the measuring point. The improvement of infrared optics is to increase the close focus characteristic, which can provide measurements on small target areas, and can also prevent the influence of background temperature. Field of view, make sure that the target is larger than the spot size of the infrared thermometer. The smaller the target, the closer it should be. When accuracy is critical, make sure the target is at least 2 times the spot size.
4. Kif tkejjel it-temperatura bit-termometru infra-aħmar? Shenzhen Yuanhengtong Technology Co., Ltd.
Sabiex tkejjel it-temperatura tat-termometru infra-aħmar, timmira t-termometru infra-aħmar fl-oġġett li għandu jitkejjel, agħfas il-grillu biex taqra d-dejta tat-temperatura fuq l-LCD tal-istrument, u tiżgura li l-proporzjon tad-distanza mad-daqs tal-post u l-kamp viżiv jiġu rranġati. Hemm ftit affarijiet importanti li għandek tiftakar meta tuża termometru infra-aħmar:
1. Only the surface temperature is measured, and the infrared thermometer cannot measure the internal temperature.
2. It-temperatura ma tistax titkejjel permezz tal-ħġieġ. Il-ħġieġ għandu karatteristiċi speċjali ħafna ta' riflessjoni u trasmissjoni, u l-qari tat-temperatura infra-aħmar mhumiex permessi. Iżda t-temperatura tista 'titkejjel mit-tieqa infra-aħmar. Termometri infra-aħmar mhumiex maħsuba għall-użu fuq uċuħ tal-metall tleqq jew illustrati (azzar li ma jissaddadx, aluminju, eċċ.).
3. Locate the hot spot. To find the hot spot, the instrument aims at the target, and then scans up and down on the target until the hot spot is determined.
4. Pay attention to environmental conditions: steam, dust, smoke, etc. It blocks the optical system of the instrument and affects temperature measurement.
5. Ambient temperature. If the infrared thermometer is suddenly exposed to an ambient temperature difference of 20 degrees or higher, allow the instrument to adjust to the new ambient temperature within 20 minutes.
5. What are the most common applications of infrared thermometers? Shenzhen Yuanhengtong Technology Co., Ltd.
Hemm ħafna applikazzjonijiet għal termometri infra-aħmar mingħajr kuntatt, l-aktar komuni huma:
1. Automotive industry: Diagnose cylinders and heating/cooling systems.
2. HVAC: Monitor air stratification, supply/return records, and furnace performance.
3. Elettriku: Iċċekkja għal transformers difettużi, pannelli elettriċi u konnetturi.
4. Food: scan management, service and storage temperature.
5. Others: many projects, bases and transformation applications.
