Cov Lus Nug & Cov Lus Teb ntawm Infrared Thermometer Technology
1. Vim li cas thiaj siv lub ntsuas kub tsis sib cuag infrared?
Cov ntsuas kub tsis sib cuag infrared siv cov thev naus laus zis infrared los ntsuas qhov kub thiab txias ntawm cov khoom. Tau txais kev ntsuas kub sai sai yam tsis muaj kev sib cuag nrog cov khoom ntsuas. Tsuas yog tsom, nias lub khawm, thiab nyeem cov ntaub ntawv ntsuas kub ntawm LCD zaub. Cov ntsuas kub infrared yog lub teeb yuag, me me, siv tau yooj yim, thiab ntseeg tau tias ntsuas kub, muaj kev phom sij, lossis cov khoom hnyav ncav cuag yam tsis muaj paug lossis ua rau cov khoom raug ntsuas. Cov ntsuas kub infrared tuaj yeem siv sijhawm ntau nyeem ib ob, thaum tiv tauj cov ntsuas kub siv sijhawm ob peb feeb los ntsuas ib ob.
2. Lub ntsuas kub infrared ua haujlwm li cas?
Cov ntsuas kub infrared tau txais qhov pom tsis pom lub zog infrared tawm los ntawm ntau yam khoom lawv tus kheej. Infrared tawg yog ib feem ntawm cov electromagnetic spectrum, uas muaj xws li xov tooj cua tsis, microwaves, pom lub teeb, ultraviolet, R-rays thiab X-rays. Infrared nyob nruab nrab ntawm lub teeb pom kev thiab xov tooj cua nthwv dej. Infrared wavelengths feem ntau qhia nyob rau hauv microns, thiab lub wavelength ntau yog 0.7 microns rau 1000 microns. Qhov tseeb, 0.7 microns rau 14 microns band yog siv rau cov ntsuas kub infrared.
3. Yuav ua li cas txhawm rau ntsuas qhov ntsuas kub ntawm qhov ntsuas kub infrared?
Kev nkag siab tsis sib haum xeeb ntawm infrared thev naus laus zis thiab nws cov hauv paus ntsiab lus rau nws qhov ntsuas qhov kub thiab txias. Thaum ntsuas qhov ntsuas kub ntawm lub ntsuas kub infrared, lub zog infrared tso tawm los ntawm cov khoom ntsuas tau hloov mus rau hauv cov teeb liab hluav taws xob ntawm lub ntsuas ntsuas los ntawm qhov ntsuas qhov muag ntawm qhov ntsuas kub infrared, thiab qhov ntsuas kub nyeem ntawm lub teeb liab tau tshwm sim. Qhov tseem ceeb tshaj plaws yog emissivity, thaj tsam ntawm qhov pom, qhov deb ntawm qhov chaw thiab qhov chaw ntawm qhov chaw. Emissivity, tag nrho cov khoom muaj kev cuam tshuam, xa, thiab emit lub zog, thiab tsuas yog lub zog emission muab ib qho kev qhia ntawm cov khoom kub. Thaum lub ntsuas kub infrared ntsuas qhov kub thiab txias, qhov ntsuas tau txais tag nrho peb hom zog. Yog li ntawd, tag nrho cov ntsuas kub infrared yuav tsum tau kho kom nyeem tsuas yog emission zog. Kev ntsuas qhov yuam kev feem ntau tshwm sim los ntawm lub zog infrared cuam tshuam los ntawm lwm qhov chaw teeb pom kev zoo. Qee qhov ntsuas kub infrared tuaj yeem sib txawv ntawm emissivity, thiab emissivity qhov tseem ceeb rau ntau yam ntaub ntawv tuaj yeem pom hauv cov ntawv luam tawm emissivity. Lwm cov cuab yeej raug kho nrog qhov emissivity preset ntawm 0.95. Tus nqi emissivity no yog rau qhov kub thiab txias ntawm feem ntau cov ntaub ntawv organic, pleev xim los yog oxidized nto, thiab yog them los ntawm kev siv ib daim kab xev los yog tiaj tus xim dub rau saum npoo raug ntsuas. Thaum cov ntaub nplaum los yog cov kua roj vanish nce mus txog qhov kub ntawm tib yam li cov khoom siv hauv paus, ntsuas qhov kub ntawm qhov chaw ntawm daim kab xev los yog cov kua roj vanish, uas yog nws qhov kub thiab txias. Qhov ratio ntawm qhov deb mus rau qhov chaw. Lub tshuab kho qhov muag ntawm tus pas ntsuas kub infrared sau lub zog los ntawm lub voj voog ntsuas qhov chaw thiab tsom nws rau ntawm qhov ntsuas. Qhov kev daws teeb meem kho qhov muag tau txhais raws li qhov piv ntawm qhov kev ncua deb ntawm lub ntsuas kub infrared mus rau qhov khoom thiab qhov loj ntawm qhov chaw yuav ntsuas (D :S). Qhov loj dua qhov sib piv, qhov zoo dua qhov kev daws teeb meem ntawm tus pas ntsuas kub infrared thiab qhov me me ntawm qhov ntsuas qhov loj me. Laser aiming, tsuas yog pab hauv aiming ntawm qhov ntsuas. Kev txhim kho tsis ntev los no hauv infrared optics yog qhov sib ntxiv ntawm qhov ze-tsim feature uas muab cov kev ntsuas tseeb ntawm cov phiaj xwm me me thiab tiv thaiv kev tiv thaiv kev kub ntxhov tom qab. Field of view, xyuas kom meej tias lub hom phiaj loj dua qhov chaw loj ntawm qhov ntsuas kub infrared. Lub hom phiaj me dua, qhov ze nws yuav tsum yog. Thaum qhov tseeb yog qhov tseem ceeb, xyuas kom lub hom phiaj yog tsawg kawg 2 npaug ntawm qhov chaw loj.
4. How to measure temperature with red>infrared tus pas ntsuas kub?
Txhawm rau ntsuas qhov ntsuas kub ntawm lub ntsuas kub infrared, tsom lub ntsuas kub infrared ntawm qhov khoom ntsuas, nias lub ntsuas kom nyeem cov ntaub ntawv ntsuas kub ntawm LCD ntawm lub ntsuas ntsuas, thiab xyuas kom meej tias qhov sib piv ntawm qhov deb mus rau qhov chaw loj thiab thaj chaw saib yog npaj. Muaj ob peb yam tseem ceeb uas yuav tsum nco ntsoov thaum siv lub ntsuas kub infrared:
1. Tsuas yog ntsuas qhov kub ntawm qhov chaw, thiab tus pas ntsuas kub infrared tsis tuaj yeem ntsuas qhov kub ntawm sab hauv.
2. Qhov kub tsis tuaj yeem ntsuas los ntawm iav. Cov iav muaj qhov cuam tshuam tshwj xeeb thiab kis tau tus yam ntxwv, uas tsis tso cai rau qhov ntsuas kub ntawm infrared. Tab sis qhov ntsuas kub tuaj yeem ntsuas los ntawm lub qhov rais infrared. Cov ntsuas kub infrared yog qhov zoo tshaj plaws tsis siv rau qhov ntsuas kub ntawm qhov ci lossis polished hlau (stainless steel, aluminium, thiab lwm yam).
3. Nrhiav qhov chaw kub. Yuav kom nrhiav tau qhov chaw kub, qhov ntsuas tsom rau ntawm lub hom phiaj, thiab tom qab ntawd scans nce thiab nqis ntawm lub hom phiaj kom txog rau thaum qhov kub tau txiav txim siab.
4. Ua tib zoo saib xyuas cov xwm txheej ib puag ncig: chav dej, plua plav, pa taws, thiab lwm yam. Nws thaiv kev kho qhov muag ntawm qhov ntsuas thiab cuam tshuam rau qhov ntsuas kub kom raug.
5. Ambient kub. Yog hais tias tus ntsuas kub infrared dheev raug rau qhov kub ntawm qhov sib txawv ntawm 20 degrees lossis siab dua, tso cai rau lub ntsuas kub hloov mus rau qhov ntsuas kub ntawm ambient hauv 20 feeb.
