Ukwembiwa kweThermometer eKhuselekileyo ngokwe-Infrared CWH800

Umzekelo: CWH800

Intshayelelo:
Itekhnoloji yokulinganisa ubushushu be-infrared iye yaphuhliswa ukuskena kunye nokulinganisa iqondo lobushushu kwindawo etshintshayo, imisele umfanekiso wokusasazwa kobushushu bayo, kwaye ibone ngokukhawuleza umahluko ofihlakeleyo wobushushu.Lo ngumfanekiso we-infrared thermal.Umfanekiso we-infrared thermal waqala ukusetyenziswa emkhosini, iNkampani yase-United States TI yaphuhlisa inkqubo yokuqala yehlabathi yokuskena ukuskena kwe-infrared ngo-19 ″.Kamva, iteknoloji ye-infrared thermal imaging iye yasetyenziswa kwiinqwelomoya, iitanki, iinqanawa zemfazwe kunye nezinye izixhobo kumazwe aseNtshona.Njengenkqubo yokujoliswa kwe-thermal kwiithagethi zokujongwa kwakhona, iphucule kakhulu Ikhono lokukhangela kunye nokubetha iithagethi.Iithemometha ze-infrared ze-Fluke zikwindawo ephambili kubuchwephesha boluntu.Nangona kunjalo, indlela yokwenza itekhnoloji yokulinganisa ubushushu be-infrared isetyenziswe ngokubanzi isesisifundo sokusetyenziswa ekufuneka sifundwe.

Umgaqo wethermometer
I-thermometer ye-infrared iqulunqwe yinkqubo ye-optical, i-photodetector, i-amplifier yesignali, i-signal processing, imveliso yokubonisa kunye nezinye iindawo.Inkqubo ye-optical igxininise amandla emitha ye-infrared ekujoliswe kuyo kwintsimi yayo yokujonga, kwaye ubungakanani bendawo yokujonga buchongwa ngamalungu optical we-thermometer kunye nendawo yayo.Amandla e-infrared agxininise kwi-photodetector kwaye aguqulelwe kwisignali yombane ehambelanayo.Umqondiso udlula kwi-amplifier kunye ne-signal processing circuit, kwaye iguqulwa ibe yixabiso lokushisa kwithagethi elinganisiweyo emva kokulungiswa ngokwe-algorithm yangaphakathi yesixhobo kunye nokukhutshwa okujoliswe kuyo.

Kwindalo, zonke izinto ezinobushushu obungaphezulu kunoziro opheleleyo zihlala zikhupha amandla emitha ye-infrared kwindawo engqongileyo.Ubungakanani bamandla emitha ye-infrared yento kunye nokuhanjiswa kwayo ngokobude be-wavelength-banobudlelwane obusondeleyo kunye nobushushu bayo bomphezulu.Ngoko ke, ngokulinganisa amandla e-infrared akhutshwa yinto ngokwayo, ubushushu bomhlaba bunokuqinisekiswa ngokuchanekileyo, eyona njongo isekelwe kuyo umlinganiselo wobushushu bemitha ye-infrared.

I-Infrared Thermometer Principle Umzimba omnyama yiradiyetha efanelekileyo, ithatha onke amaza amandla akhanyayo, akukho mbonakaliso okanye ukuhanjiswa kwamandla, kunye nokukhutshwa komphezulu wayo ngu-1. Nangona kunjalo, izinto ezichanekileyo kwindalo phantse azikho imizimba emnyama.Ukuze kucaciswe kwaye kufumaneke ukuhanjiswa kwemisebe ye-infrared, imodeli efanelekileyo kufuneka ikhethwe kuphando lwethiyori.Le yimodeli ye-oscillator elinganisiweyo yemitha yomgodi womzimba ecetywe nguPlack.Umthetho we-Planck blackbody radiation uthatyathwe, oko kukuthi, i-blackbody spectral radiance ebonakaliswa kwi-wavelength.Esi sisiqalo sazo zonke ithiyori zemitha ye-infrared, ngoko ke ibizwa ngokuba ngumthetho wemitha ye-blackbody.Ukongeza kwi-radiation wavelength kunye nobushushu bento, isixa sokusasazeka kwemitha yazo zonke izinto zokwenyani sikwanxulumene nezinto ezinje ngodidi lwezinto ezenza into, indlela yokulungiselela, inkqubo yobushushu, kunye nemo yomphezulu kunye neemeko zokusingqongileyo. .Ngoko ke, ukwenzela ukuba umthetho we-radiation womzimba omnyama usebenze kuzo zonke izinto zangempela, i-proportionality factor enxulumene neempawu zezinto eziphathekayo kunye nomgangatho ophezulu kufuneka zifakwe, oko kukuthi, ukukhupha.Lo mlinganiso ubonisa ukuba ukusasazeka kwemitha ye-thermal yeyona nto isondele kangakanani kwi-radiation ye-blackbody, kwaye ixabiso layo liphakathi kwe-zero kunye nexabiso elingaphantsi kwe-1. Iimpawu zemitha ye-infrared yayo nayiphi na into inokwaziwa.Izinto eziphambili ezichaphazela ukukhutshwa kwezinto ezikhutshwayo zezi: uhlobo lwemathiriyeli, uburhabaxa bomphezulu, ubume bomzimba kunye neekhemikhali kunye nobukhulu bezinto.

Xa ulinganisa ubushushu bendawo ekujoliswe kuyo ngethemometha yemitha ye-infrared, qala ulinganise i-infrared radiation yethagethi ngaphakathi kwebhendi yayo, kwaye ke iqondo lobushushu lethagethi elilinganisiweyo libalwa ngethemometha.I-thermometer ye-monochromatic ihambelana nemitha ye-radiation kwibhendi;Ithemometha enemibala emibini ilingana nomlinganiselo wemitha yemitha kumacandelo amabini.

Isicelo:
I-CWH800 Ithemomitha eKhuselekileyo ngokwe-Infrared sisizukulwana esitsha sethemometha ekrelekrele ekhuselekileyo ye-infrared edityaniswe nobuchule bokubona, oomatshini kunye nombane.Isetyenziswa ngokubanzi ukulinganisa ubushushu bomphezulu wento kwindawo apho kukho iigesi ezinokutsha neziqhumayo.Inemisebenzi yokulinganisa ubushushu obungaqhagamshelwanga, isikhokelo se-laser, umboniso we-backlight, ukugcinwa kwesiboniso, i-alamu ye-voltage ephantsi, kulula ukuyisebenzisa kwaye kulula ukuyisebenzisa.Uluhlu lokuvavanya lusuka kwi -30 ℃ ukuya kwi-800 ℃.Akukho mntu uvavanya ngaphezulu kwe800℃ kulo lonke elaseTshayina.
