I-Thermometer ye-Infrared Ephephile Yokumba I-CWH800

Imodeli: CWH800

Isingeniso:
Ubuchwepheshe bokulinganisa izinga lokushisa le-infrared buthuthukiswe ukuze kuskenwe futhi kulinganiswe izinga lokushisa endaweni eshintshashintshayo ngokushisa, kunqunywe isithombe sayo sokusabalalisa izinga lokushisa, futhi kutholakale ngokushesha umehluko wokushisa ofihliwe. Lesi isithombe sokushisa se-infrared. Isithombe sokushisa se-infrared saqala ukusetshenziswa empini, i-United States TI Company yathuthukisa uhlelo lokuqala lokuhlola ukuskena kwe-infrared emhlabeni ngo-19″. Kamuva, ubuchwepheshe bokuthwebula izithombe zokushisa kwe-infrared busetshenziswe ezindizeni, emathangini, emikhunjini yempi nakwezinye izikhali emazweni aseNtshonalanga. Njengesistimu yokuqondisa ukushisa yezinhloso zokuhlola, ithuthukise kakhulu ikhono lokusesha nokushaya izinhloso. Ama-thermometer e-infrared e-Fluke asesimweni esiphambili kwezobuchwepheshe bezakhamuzi. Kodwa-ke, indlela yokwenza ubuchwepheshe bokulinganisa izinga lokushisa le-infrared busetshenziswe kabanzi kuseyisihloko sesicelo esifanele ukufundwa.

Isimiso se-thermometer
I-thermometer ye-infrared yakhiwe uhlelo lwe-optical, i-photodetector, i-signal amplifier, i-signal processing, i-display output kanye nezinye izingxenye. Uhlelo lwe-optical lugxila amandla emisebe ye-infrared ye-target ensimini yalo yokubuka, futhi ubukhulu bensimu yokubuka bunqunywa izingxenye ze-optical ze-thermometer kanye nendawo yayo. Amandla e-infrared agxile ku-photodetector futhi aguqulwa abe isignali kagesi ehambisanayo. Isignali idlula ku-amplifier kanye nesekethe yokucubungula isignali, futhi iguqulwa ibe yinani lokushisa le-target elinganisiwe ngemuva kokulungiswa ngokwe-algorithm yangaphakathi yethuluzi kanye ne-target emissivity.

Ngokwemvelo, zonke izinto ezinokushisa okuphezulu kuno-zero ophelele zihlala zikhipha amandla emisebe ye-infrared esikhaleni esizungezile. Ubukhulu bamandla emisebe ye-infrared yento kanye nokusatshalaliswa kwayo ngokwe-wavelength-kunobuhlobo obuseduze kakhulu nokushisa kwayo kobuso. Ngakho-ke, ngokulinganisa amandla e-infrared akhishwa yinto ngokwayo, izinga lokushisa lobuso bayo linganqunywa ngokunembile, okuyisisekelo esiqondile lapho kulinganiswa khona izinga lokushisa kwemisebe ye-infrared.

Isimiso Sokushisa Kwe-Infrared Umzimba omnyama uyi-radiator efanelekile, umunca wonke amaza okukhanya kwamandla akhanyayo, akukho ukubonakaliswa noma ukudluliselwa kwamandla, futhi ukukhishwa kobuso bawo kungu-1. Kodwa-ke, izinto zangempela emvelweni cishe azizona imizimba emnyama. Ukuze kucaciswe futhi kutholakale ukusatshalaliswa kwemisebe ye-infrared, imodeli efanele kumele ikhethwe ocwaningweni lwethiyori. Lena imodeli ye-oscillator elinganiselwe yemisebe yomzimba ephakanyisiwe nguPlanck. Umthetho wemisebe ye-Planck blackbody uthathwe, okungukuthi, ukukhanya kwe-spectral ye-blackbody okuvezwe ku-wavelength. Lena yindawo yokuqala yazo zonke izinkolelo-mbono zemisebe ye-infrared, ngakho-ke ibizwa ngokuthi umthetho wemisebe ye-blackbody. Ngaphezu kobude bokukhanya kanye nokushisa kwento, inani lemisebe lazo zonke izinto zangempela lihlobene nezici ezifana nohlobo lwezinto ezakha into, indlela yokulungiselela, inqubo yokushisa, kanye nesimo sobuso kanye nezimo zemvelo. Ngakho-ke, ukuze kwenziwe umthetho wemisebe yomzimba omnyama osebenzayo kuzo zonke izinto zangempela, isici sokulingana esihlobene nezakhiwo zezinto kanye nesimo sobuso kumele sethulwe, okungukuthi, ukukhishwa. Le coefficient ikhombisa ukuthi imisebe yokushisa yento yangempela iseduze kangakanani nemisebe ye-blackbody, futhi inani layo liphakathi kuka-zero kanye nenani elingaphansi kuka-1. Ngokomthetho wemisebe, uma nje ukukhishelwa kwezinto kwaziwa, izici zemisebe ye-infrared yanoma iyiphi into zingaziwa. Izici eziyinhloko ezithinta ukukhishelwa yilezi: uhlobo lwezinto, ubulukhuni bomphezulu, isakhiwo somzimba nesamakhemikhali kanye nobukhulu bezinto.

Uma ulinganisa izinga lokushisa lethagethi nge-thermometer yemisebe ye-infrared, qala ulinganise imisebe ye-infrared yethagethi ngaphakathi kwebhendi yayo, bese kubalwa izinga lokushisa lethagethi elilinganisiwe nge-thermometer. I-thermometer ye-monochromatic ilingana nemisebe ebhendini; i-thermometer enemibala emibili ilingana nesilinganiso semisebe ebhendini ezimbili.

Isicelo:
I-CWH800 Intrinsically Safe Infrared Thermometer iyisizukulwane esisha se-thermometer ehlakaniphile ephephile ngaphakathi ehlanganiswe nobuchwepheshe bokubona, bomshini kanye nobe-elekthronikhi. Isetshenziswa kabanzi ukukala izinga lokushisa lezinto endaweni lapho kukhona khona amagesi avuthayo naqhumayo. Inemisebenzi yokulinganisa izinga lokushisa elingathintani, umhlahlandlela we-laser, isibonisi sangemuva, ukugcina izibonisi, i-alamu ye-voltage ephansi, kulula ukuyisebenzisa futhi kulula ukuyisebenzisa. Ububanzi bokuhlola busukela ku--30℃ kuya ku-800℃. Akekho ohlola ngaphezu kuka-800℃ kulo lonke elaseShayina.
