Lub hauv paus ntsiab lus ua haujlwm ntawm illuminance meter _Cov kev cai dav dav thiab kev faib tawm ntawm lub ntsuas hluav taws xob
Lub teeb Meters ua haujlwm li cas
Siv lub germanium photocell ua ib qho kev sojntsuam, qhov tam sim no tsim los ntawm photocell yog qhov sib txawv vim qhov sib txawv ntawm lub teeb, thiab tom qab ntawd qhov tam sim no yog amplified los ntawm DC, thiab tom qab ntawd DC teeb liab tau hloov mus rau hauv cov teeb liab uas ncaj qha cuam tshuam qhov kev siv ntawm lub teeb. los ntawm kev hloov pauv digital-rau-analog circuit.
General Requirements rau Luxmeters
1. CompactSize, LightWeight
Lub sijhawm siv lub ntsuas hluav taws xob yog qhov dav heev, thiab lub sijhawm ntawm daim ntawv thov feem ntau nyob hauv ntau qhov chaw, yog li thawj qhov yuav tsum tau ua ua ntej rau lub ntsuas hluav taws xob portable yog qhov me me thiab lub teeb yuag.
2. Qhov tseeb
Seb lub illuminance meter yog qhov zoo los yog tsis muaj kev sib raug zoo nrog nws qhov tseeb. Ntawm chav kawm, nws kuj yog ze ze rau nws tus nqi, yog li nws yog ib qho tsim nyog yuav tau yuav ib lub lux meter nrog qhov tseeb ntawm tus nqi tsim nyog. Feem ntau, qhov yuam kev yuav tsum tsis pub tshaj ± 15 feem pua.
3. Xim Xim
Cov hom teeb pom kev zoo yog tag nrho-encompassing. Qee qhov tsom mus rau cov teeb liab siab siab nrog lub wavelengths ntev, los yog xiav-violet nrog luv wavelengths xws li Daylight fluorescent teeb; kuj tseem muaj ntau qhov sib npaug sib npaug xws li incandescent noob series. Qhov rhiab heev ntawm tib lub teeb pom kev zoo rau qhov sib txawv wavelengths yuav txawv me ntsis. Yog li ntawd, yuav tsum tau them nyiaj kom tsim nyog.
4. Cosine Compensation
Peb txhua tus paub tias qhov ci ntsa iab ntawm qhov ci ntsa iab yog cuam tshuam nrog qhov xwm txheej ntawm lub teeb ci. Ib yam li ntawd, thaum ntsuas nrog lub teeb ntsuas lub teeb, qhov xwm txheej ntawm lub ntsuas hluav taws xob (Sensor) thiab lub teeb pom kev zoo yuav cuam tshuam rau kev nyeem ntawv tus nqi ntawm lub teeb ntsuas. Yog li ntawd, seb lub ntsuas hluav taws xob zoo puas muaj lub luag haujlwm ntawm cosine them nyiaj tsis tuaj yeem tsis quav ntsej.
Classification ntawm illuminance meters
1. Visual illuminance meter: nws tsis yooj yim rau siv, qhov tseeb tsis siab, thiab nws tsis tshua siv.
2. Photoelectric illuminance meter: selenium photocell illuminance meter thiab silicon photocell illuminance meter yog feem ntau siv.
Kev siv Luxmeter
1. Daim ntawv thov nyob rau hauv cov chaw pej xeem
Txhawm rau kom ntseeg tau tias tib neeg tuaj yeem nyob hauv lub teeb pom kev zoo, peb lub teb chaws tau tsim cov qauv kev noj qab haus huv rau sab hauv tsev (nrog rau cov chaw pej xeem) illuminance, thiab siv illuminometers los ntsuas qhov illuminance ntawm ntau qhov chaw.
2. Kev lag luam teeb pom kev zoo, kev lag luam yees duab, theem teeb pom kev zoo, thiab lwm yam.
Lub illuminance meter tau ua tiav rau ntau lub tswv yim, xws li kev lag luam teeb pom kev lag luam, kev lag luam yees duab, theem teeb pom kev zoo, thiab lwm yam. Cov qauv sib txawv ntawm cov illuminance meters tuaj yeem ua tau raws li kev ntsuas sib txawv.
3. Factory ntau lawm kab thov
Nyob rau hauv lub Hoobkas, qhov yuav tsum tau illumination ntawm cov kab ntau lawm kuj nruj, kev ua hauj lwm tas mus li yuav ua rau pom kev qaug zog, thiab kev ua hauj lwm efficiency yuav txo tau heev. Feem ntau, qhov yuav tsum tau teeb pom kev zoo yog ntau dua lossis sib npaug rau 1000Lx. Rau qhov chaw uas muaj qhov xav tau teeb pom kev zoo siab, xaiv lub ntsuas hluav taws xob loj loj tuaj yeem xaiv. tuaj yeem cuam tshuam nrog kev ntsuas lub teeb pom kev zoo.
4. Daim ntawv thov ntawm lub ntsuas hluav taws xob yog qhov dav heev, suav nrog cov ntawv thov hauv peb lub neej niaj hnub, xws li cov chaw tsim khoom, tsev khaws khoom, tsev kawm ntawv, chaw ua haujlwm, tsev, kev tsim teeb pom kev zoo, chav kuaj thiab lwm yam.
