I-Thermometer ye-Infrared ekhuselekileyo yokumba ngaphakathi CWH800

Imodeli: CWH800

Intshayelelo:
Itekhnoloji yokulinganisa ubushushu be-infrared iye yaphuhliswa ukuze iskene kwaye ilinganise ubushushu kumphezulu otshintsha ubushushu, imisele umfanekiso wayo wokusasazwa kobushushu, kwaye ibone ngokukhawuleza umahluko ofihliweyo wobushushu. Le yi-infrared thermal imager. I-infrared thermal imager yaqala ukusetyenziswa emkhosini, i-United States TI Company yaphuhlisa inkqubo yokuqala yehlabathi yokujonga i-infrared scanning kwi-19″. Kamva, itekhnoloji yokujonga i-infrared thermal imaging iye yasetyenziswa kwiinqwelomoya, iitanki, iinqanawa zemfazwe kunye nezinye izixhobo kumazwe aseNtshona. Njengenkqubo yokujonga i-thermal kwiithagethi zokuhlola, iye yaphucula kakhulu amandla okukhangela kunye nokubetha iithagethi. Ii-thermometers ze-infrared ze-Fluke zikwindawo ephambili kwitekhnoloji yoluntu. Nangona kunjalo, indlela yokwenza itekhnoloji yokulinganisa ubushushu be-infrared esetyenziswa kakhulu isengumxholo wesicelo ofanele ukufundwa.

Umgaqo we-thermometer
I-thermometer ye-infrared yenziwe ngenkqubo ye-optical, i-photodetector, i-signal amplifier, i-signal processing, i-display output kunye nezinye iindawo. Inkqubo ye-optical igxila amandla e-infrared radiation ethagethi kwindawo yayo yokujonga, kwaye ubungakanani bentsimi yokujonga bumiselwa ziindawo ze-optical ze-thermometer kunye nendawo yayo. Amandla e-infrared agxile kwi-photodetector kwaye aguqulwa abe yisignali yombane ehambelanayo. Isignali idlula kwi-amplifier kunye nesekethe yokucubungula isignali, kwaye iguqulwa ibe lixabiso lobushushu lethagethi elinganisiweyo emva kokuba ilungisiwe ngokwe-algorithm yangaphakathi yesixhobo kunye ne-target emissivity.

Ngokwendalo, zonke izinto ezinobushushu obuphezulu kuno-zero opheleleyo zihlala zikhupha amandla emitha ye-infrared kwindawo ejikelezileyo. Ubungakanani bamandla emitha ye-infrared yento kunye nokusasazwa kwayo ngokwe-wavelength-zinobudlelwane obusondeleyo kakhulu nobushushu bayo bomphezulu. Ke ngoko, ngokulinganisa amandla e-infrared akhutshwa yinto ngokwayo, ubushushu bayo bomphezulu bunokugqitywa ngokuchanekileyo, nto leyo esisiseko esisekelwe kuso umlinganiselo wobushushu bemitha ye-infrared.

Umgaqo weThermometer ye-Infrared Umzimba omnyama yi-radiator efanelekileyo, ifunxa zonke ii-wavelengths zamandla akhanyayo, akukho kukhanya okanye ukudluliselwa kwamandla, kwaye ukukhupha kwamanzi kumphezulu wawo yi-1. Nangona kunjalo, izinto zokwenyani kwindalo azifani nemizimba emnyama. Ukuze kucaciswe kwaye kufumaneke ukusasazwa kwemitha ye-infrared, imodeli efanelekileyo kufuneka ikhethwe kuphando lwethiyori. Le yimodeli ye-oscillator elinganisiweyo yemitha ye-body cavity ecetywayo nguPlanck. Umthetho wemitha ye-Planck blackbody ufunyenwe, oko kukuthi, ukukhanya kwe-spectral spectral okuchazwe kwi-wavelength. Le yindawo yokuqala yazo zonke iithiyori zemitha ye-infrared, ngoko ke ibizwa ngokuba ngumthetho wemitha ye-blackbody. Ukongeza kwi-wavelength yemitha kunye nobushushu bento, ubungakanani bemitha ye-radiation yazo zonke izinto zokwenyani bukwanxulumene nezinto ezifana nohlobo lwezinto ezenza into, indlela yokulungiselela, inkqubo yobushushu, kunye nemeko yomphezulu kunye neemeko zokusingqongileyo. Ke ngoko, ukuze kwenziwe umthetho wemitha ye-black body esebenzayo kuzo zonke izinto zokwenyani, kufuneka kungeniswe into ehambelana neempawu zezinto kunye nemeko yomphezulu, oko kukuthi, ukukhupha amanzi. Le coefficient ibonisa ukuba imitha yobushushu yento yokwenyani ikufutshane kangakanani nemitha yomnyama, kwaye ixabiso layo liphakathi kwe-zero kunye nexabiso elingaphantsi kwe-1. Ngokomthetho wemitha, lo gama nje imitha yobushushu yento isaziwa, iimpawu zemitha yobushushu ye-infrared yayo nayiphi na into zinokwaziwa. Izinto eziphambili ezichaphazela imitha yobushushu zezi: uhlobo lwezinto, uburhabaxa bomphezulu, ulwakhiwo lomzimba kunye neekhemikhali kunye nobukhulu bezinto.

Xa ulinganisa ubushushu bethagethi nge-thermometer yemitha ye-infrared, qala ulinganise ubushushu bethagethi ngaphakathi kwebhendi yayo, uze emva koko ubushushu bethagethi elinganisiweyo bubalwe yi-thermometer. I-thermometer ye-monochromatic ilingana nobushushu obukwibhendi; i-thermometer enemibala emibini ilingana nomlinganiselo wemitha kwiibhendi ezimbini.

Isicelo:
I-CWH800 Intrinsically Safe Infrared Thermometer sisizukulwana esitsha se-infrared thermometer ekrelekrele nekhuselekileyo edityaniswe nobuchule bokubona, boomatshini kunye nobombane. Isetyenziswa kakhulu ukulinganisa ubushushu bomphezulu wento kwindawo apho kukho iigesi ezinokutsha neziqhumayo. Inemisebenzi yokulinganisa ubushushu obungadibaniyo, isikhokelo selaser, isibonisi se-backlight, ukugcina izibonisi, i-alarm ye-voltage ephantsi, kulula ukuyisebenzisa kwaye kulula ukuyisebenzisa. Uluhlu lovavanyo luqala kwi--30℃ ukuya kwi-800℃. Akukho mntu uvavanya ngaphezulu kwe-800℃ kulo lonke elaseTshayina.
