Mining Intrinsically Safe Infrared Thermometer CWH800

Chitsanzo: CWH800

Chiyambi:
Ukadaulo woyezera kutentha kwa infrared wapangidwa kuti uzitha kuyang'ana ndikuyeza kutentha pamalo osinthika, kudziwa chithunzi chake chogawa kutentha, ndikuzindikira mwachangu kusiyana kobisika kwa kutentha.Ichi ndi chojambula cha infrared thermal.Chifaniziro cha infrared thermal thermal chidagwiritsidwa ntchito koyamba m'gulu lankhondo, United States TI Company idapanga makina oyamba padziko lonse lapansi ozindikira ma infrared scanning mu 19 ″.Pambuyo pake, luso la kujambula kwa infrared thermal imaging lakhala likugwiritsidwa ntchito mu ndege, akasinja, zombo zankhondo ndi zida zina m'mayiko a Kumadzulo.Monga njira yowunikira matenthedwe pazolinga zowunikiranso, zasintha kwambiri Kutha kusaka ndikugunda zomwe mukufuna.Fluke infrared thermometers ali pamalo otsogola muukadaulo wamba.Komabe, momwe mungapangire tekinoloji yoyezera kutentha kwa infrared kuti igwiritsidwe ntchito kwambiri ikadali phunziro loyenera kuphunzira.

Mfundo ya thermometer
Thermometer ya infrared imapangidwa ndi optical system, photodetector, amplifier ya chizindikiro, kukonza ma siginecha, kutulutsa kowonetsera ndi magawo ena.Dongosolo la kuwala limayang'ana mphamvu ya infrared radiation ya chandamale m'munda wake, ndipo kukula kwa gawo lowonera kumatsimikiziridwa ndi mbali za kuwala kwa thermometer ndi malo ake.Mphamvu ya infrared imayang'ana pa photodetector ndikusinthidwa kukhala chizindikiro chamagetsi chofananira.Chizindikirocho chimadutsa pa amplifier ndi ma signal processing circuit, ndipo chimasinthidwa kukhala mtengo wa kutentha kwa chandamale choyezedwa pambuyo pokonzedwa molingana ndi ndondomeko ya mkati mwa chipangizocho ndi kutulutsa kwachindunji.

Mwachilengedwe, zinthu zonse zomwe kutentha kwake kumakhala kopitilira ziro nthawi zonse zimatulutsa mphamvu ya radiation ya infrared kupita kumalo ozungulira.Kukula kwa infrared kuwala mphamvu ya chinthu ndi kugawa kwake molingana ndi wavelength - ali ndi ubale wapamtima ndi pamwamba kutentha kwake.Chifukwa chake, poyeza mphamvu ya infrared yomwe imawululidwa ndi chinthucho, kutentha kwake kumatha kutsimikiziridwa molondola, chomwe ndi cholinga chomwe kuyeza kwa kutentha kwa ma radiation kumayambira.

Mfundo ya Thermometer ya Infrared Thupi lakuda ndi radiator yodziwika bwino, imatenga mafunde onse a mphamvu yowunikira, palibe kuwonetsera kapena kufalitsa mphamvu, ndipo kutuluka kwa mpweya wake ndi 1. Komabe, zinthu zenizeni m'chilengedwe sizikhala matupi akuda.Kuti tifotokoze bwino ndikupeza kugawidwa kwa ma radiation a infrared, chitsanzo choyenera chiyenera kusankhidwa mu kafukufuku wamaganizo.Uwu ndiye mtundu wa quantized oscillator wama radiation am'mimba omwe aperekedwa ndi Planck.Lamulo la ma radiation a Planck blackbody limachokera, ndiko kuti, kuwala kwa blackbody spectral komwe kumasonyezedwa mu wavelength.Apa ndiye poyambira malingaliro onse a radiation ya infrared, motero amatchedwa lamulo la radiation ya blackbody.Kuphatikiza pa kutalika kwa ma radiation ndi kutentha kwa chinthucho, kuchuluka kwa ma radiation azinthu zonse zenizeni kumakhudzananso ndi zinthu monga mtundu wazinthu zomwe zimapanga chinthucho, njira yokonzekera, njira yotenthetsera, komanso mawonekedwe apamwamba komanso chilengedwe. .Choncho, kuti apange lamulo lakuda lakuda lakuda kuti likhale logwirizana ndi zinthu zonse zenizeni, chinthu chofanana chokhudzana ndi katundu wa zinthu ndi malo apamwamba chiyenera kuyambitsidwa, ndiko kuti, kutulutsa mpweya.Coefficient iyi imasonyeza momwe kutentha kwa kutentha kwa chinthu chenichenicho kuli pafupi ndi ma radiation a blackbody, ndipo mtengo wake uli pakati pa zero ndi mtengo wocheperapo 1. Malinga ndi lamulo la ma radiation, malinga ngati kutuluka kwa zinthuzo kumadziwika, Mawonekedwe a infrared radiation a chinthu chilichonse amatha kudziwika.Zinthu zazikulu zomwe zimakhudza kutulutsa mpweya ndi: mtundu wazinthu, roughness pamwamba, thupi ndi mankhwala kapangidwe ndi makulidwe a zinthu.

Mukayeza kutentha kwa chandamale ndi thermometer ya infrared radiation, choyamba yezani ma radiation a chandamale mkati mwa gulu lake, ndiyeno kutentha kwa chandamale kumawerengedwa ndi thermometer.The monochromatic thermometer ndi molingana ndi cheza mu gulu;thermometer yamitundu iwiri imagwirizana ndi chiŵerengero cha ma radiation m'magulu awiriwa.

Ntchito:
CWH800 Intrinsically Safe Infrared Thermometer ndi m'badwo watsopano wama thermometer anzeru otetezedwa ndi infrared ophatikizidwa ndi luso la kuwala, makina ndi zamagetsi.Amagwiritsidwa ntchito kwambiri poyezera kutentha kwa chinthu pamalo pomwe pali mpweya woyaka komanso wophulika.Ili ndi ntchito zoyezera kutentha kosalumikizana, chiwongolero cha laser, mawonedwe a backlight, kusunga mawonedwe, alamu yotsika yamagetsi, yosavuta kugwiritsa ntchito komanso yosavuta kugwiritsa ntchito.Mitundu yoyesera imachokera ku -30 ℃ mpaka 800 ℃.Palibe amene amayesa kuposa 800 ℃ kuzungulira China.
