Lub teeb siv ntsuas ntsuas qhov ntsuas feem ntau yog siv rau hauv cov khoom ntawd. Lub teeb meter yog ib hom kev luam ntawv tsis siv neeg optical fiber. Nws yog ib qho khoom siv kho qhov muag rau kev ntsuas qhov siv ntawm cov teeb pom kev zoo thiab lub teeb ntuj. Nws daws qhov teeb meem ntawm kev ntsuas tsis tu ncua ntawm lub teeb siv thiab tsis siv neeg kaw. Nws yog tsim los ntawm photodetector, ib qho kev hloov pauv tsis siv neeg amplifying Circuit Court, lub kaw lus nkhaus, lub tshuab luam ntawv digital thiab ib qho khoom siv tam sim no digital. Nws yog tsim los ntawm cov cell photovoltaic thiaj li pom cov spectral teb nkhaus conforms rau tib neeg pom spectral nkhaus tau teev tseg los ntawm Commission on Illumination (CIE). Portable illuminance meter belongs rau kev ua haujlwm ntawm kev ntsuas qhov pom kev, thiab tsim nyog rau kev ntsuas qhov pom kev hauv kev ua liaj ua teb, lub neej txhua hnub, thiab kev mus ncig sab nraud. Nws siv lub photoresistor ua ib qho khoom siv hluav taws xob hloov hluav taws xob, thiab nws muaj cov khoom siv hluav taws xob DC, uas yog txuas nrog lub zog hloov hluav taws xob, hloov hluav taws xob, photoresistor, ntsuas Circuit Court, A / D converter, decoder, tus tsav tsheb. thiab ib qho zaub ntawm qhov tso zis kawg ntawm DC fais fab mov. . Lub SO 200K lub teeb siv ntsuas ntsuas tsis txhob siv lub taub hau kho qhov muag, DC fais fab mov tsuas yog xav tau 9VBlock roj teeb, thiab lub tshuab txiav tawm, tso saib tsav tsheb thiab cov khoom siv sib xyaw ua ke ntawm daim npav sib xyaw ua ke, ua kom yooj yim hauv cov qauv, me me, thiab yooj yim txav. Nws muaj qhov zoo ntawm kev teb thiab lwm yam. Ib qho ultraviolet hluav taws xob illuminometer belongs rau qhov ntsuas qhov muag pom. Nws yog tus cwj pwm nyob rau hauv uas nws yog tsim los ntawm ob txoj kev txiav-tawm optical lim thiab ob zoo tib yam photoelectric receivers los tsim ib tug dual optical path detector, thiab lub Circuit Court ib feem txais ob txoj kev amplification, thiaj li hais tias tus nqi hluav taws xob ntawm qhov yuav tsum tau kuaj band. tuaj yeem ntsuas qhov tseeb. Kev ntsuas lub hauv paus ntsiab lus ntawm illuminometer nrog lub zog astigmatism txiav tawm: Illuminance yog qhov ntom ntom ntawm cov luminous flux tau txais ntawm lub dav hlau illuminated. Lub illuminometer yog ib qho cuab yeej siv los ntsuas qhov illuminance ntawm lub illuminated nto, thiab nws yog ib qho ntawm cov cuab yeej siv tshaj plaws hauv kev ntsuas illuminance. Lub hauv paus ntsiab lus ntawm lub illuminance meter: Lub illuminance meter yog tsim los ntawm ob qhov chaw: lub taub hau luminous (tseem hu ua lub teeb tau txais kev sojntsuam, nrog rau cov receiver, V (λ) khub lim, thiab cov cosine corrector) thiab nyeem ntawv tso saib
