Txheej txheem cej luam ntawm Portable Infrared Thermometers
Txheej txheem cej luam ntawm Portable Infrared Thermometers
Lub ntsuas kub infrared muaj lub tshuab kho qhov muag, photodetector, lub teeb liab amplifier, teeb liab ua, tso zis tawm, thiab lwm yam khoom. Lub tshuab kho qhov muag sib sau ua ke lub zog hluav taws xob infrared ntawm lub hom phiaj hauv nws qhov kev pom, thiab lub zog infrared tau tsom mus rau lub photodetector thiab hloov mus rau cov khoom siv hluav taws xob sib xws. Cov teeb liab no ces hloov mus rau qhov kub ntawm qhov ntsuas lub hom phiaj.
Cov yam ntxwv ua haujlwm ntawm portable infrared tus pas ntsuas kub
Tus pas ntsuas kub infrared tuaj yeem ntsuas qhov ntsuas kub sai sai, thiab nyob rau lub sijhawm ntawm kev nyeem cov ntawv txuas txuas nrog lub ntsuas kub, qhov ntsuas kub yuav luag tag nrho cov ntsiab lus sib txuas tuaj yeem nyeem tau siv lub ntsuas kub infrared. Tsis tas li ntawd, vim yog cov khoom thiab lub teeb yuag ntawm lub ntsuas kub infrared (tag nrho cov sib zog dua 10 ooj), thiab nws yooj yim tso rau hauv rooj plaub tawv thaum tsis siv. Yog li koj tuaj yeem nqa nrog koj thaum lub sijhawm kuaj xyuas lub Hoobkas thiab kev tshuaj xyuas txhua hnub.
Lwm qhov ua tau zoo ntawm cov ntsuas kub infrared yog kev nyab xeeb, feem ntau muaj qhov tseeb ntawm tsawg dua 1 degree. Qhov kev ua tau zoo no tseem ceeb tshwj xeeb tshaj yog thaum koj ua kev tiv thaiv kev tiv thaiv, xws li kev saib xyuas cov xwm txheej hnyav thiab cov xwm txheej tshwj xeeb uas yuav ua rau cov khoom puas tsuaj lossis lub sijhawm poob. Vim tias feem ntau cov cuab yeej siv thiab cov chaw tsim khoom ua haujlwm rau 365 hnub, kev poob qis yog sib npaug los txo cov nyiaj tau los. Txhawm rau tiv thaiv qhov kev poob zoo li no, luam theej duab txhua yam khoom siv hluav taws xob hauv tsev - Circuit Court breakers, transformers, fuses, keyboards, buses, thiab faib boards kom pom hotspots. Nrog lub ntsuas kub infrared, koj tuaj yeem tshawb xyuas qhov hloov pauv me me hauv kev ua haujlwm kub, daws teeb meem thaum pib, txo cov nuj nqis thiab kev saib xyuas uas tshwm sim los ntawm cov khoom siv tsis ua haujlwm.
Portable infrared tus pas ntsuas kub ntsuas kub ntsuas ntau yam
Txiav txim siab qhov ntsuas kub ntawm qhov ntsuas kub: Qhov ntsuas kub ntsuas qhov ntsuas kub yog qhov ntsuas qhov ua tau zoo ntawm tus pas ntsuas kub. Qhov kev pab cuam ntau yam ntawm cov khoom nyob rau hauv infrared era yog -40 degree - ntxiv rau 3000 degree, tab sis qhov no tsis tuaj yeem ua tiav los ntawm ib tus qauv ntawm tus ntsuas kub infrared. Txhua tus qauv ntawm tus pas ntsuas kub muaj nws tus kheej ntsuas qhov ntsuas kub. Yog li ntawd, tus neeg siv qhov ntsuas kub ntawm qhov ntsuas kub yuav tsum raug suav tias yog qhov tseeb thiab dav, tsis yog nqaim los yog dav dhau. Raws li txoj cai lij choj blackbody hluav taws xob, kev hloov pauv ntawm hluav taws xob hluav taws xob los ntawm qhov kub thiab txias hauv qhov luv wavelength ntawm lub spectrum yuav dhau qhov kev hloov ntawm hluav taws xob hluav taws xob los ntawm kev ua yuam kev emissivity. Yog li ntawd, nws raug pom zoo kom xaiv luv wavelength kom ntau li ntau tau rau kev ntsuas kub. Feem ntau hais lus, qhov nqaim ntawm qhov ntsuas qhov ntsuas kub ntau dua, qhov siab dua qhov kev daws teeb meem ntawm cov zis tso zis rau kev ntsuas kub, thiab qhov tseeb thiab kev ntseeg tau yooj yim los daws. Yog tias qhov ntsuas qhov ntsuas kub ntau dhau, nws yuav txo qhov ntsuas qhov ntsuas qhov tseeb.
