Txheeb xyuas qhov sib txawv ntawm cov qauv siv hluav taws xob illuminance meter thiab lub ntsuas hluav taws xob zoo tib yam
Cov qauv siv hluav taws xob teeb pom kev zoo zam kev siv lub taub hau photometric, thiab DC fais fab mov tsuas yog siv 3V roj teeb. Lub decoder, tso saib tsav tsheb thiab cov zaub tau muab tso rau ntawm daim npav sib xyaw ua ke, uas ua rau nws yooj yim hauv cov qauv, me me, txav tau yooj yim, thiab muaj qhov ua tau zoo thiab lwm yam zoo. Ordinary illuminance meters siv photoresistors li photoelectric hloov dua siab tshiab pab kiag li lawm, uas muaj ib tug DC fais fab mov, thiab txuas nrog nyob rau hauv series nrog lub voltage converter Circuit Court, hloov, photoresistor, xeem Circuit Court, A / D converter, decoder, thiab tso saib tsav tsheb ntawm cov zis kawg. ntawm DC fais fab mov. thiab tso saib.
Cov yam ntxwv ntawm cov qauv siv hluav taws xob illuminance meter:
1. Qhov tseeb Seb lub lux meter yog qhov zoo lossis qhov tsis zoo nyob ntawm 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.
2. Cov hom xim them nyiaj lub teeb qhov chaw yog tag nrho-encompassing. Qee qhov tsom rau cov teeb liab siab siab nrog lub teeb ntev dua, lossis lub teeb xiav-ntsuab nrog luv luv wavelengths xws li Daylight fluorescent teeb; kuj tseem muaj ntau qhov sib npaug sib npaug xws li incandescent noob series. rhiab heev yuav txawv me ntsis, yog li yuav tsum tau them nyiaj nruab nrab.
3. Kev them nyiaj Cosine Txhua tus paub tias qhov ci ntsa iab ntawm qhov illuminated nto muaj feem xyuam rau qhov xwm txheej ntawm lub teeb qhov chaw. 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.
4. Nyob rau hauv cov nqe lus ntawm ntim thiab qhov hnyav, lub illuminance meter yuav siv tau nyob rau hauv ntau qhov chaw, thiab lub sij hawm ntawm kev siv yog feem ntau nyob rau hauv ntau qhov chaw. Yog li ntawd, portable illuminance meter nrog me me thiab lub teeb yuag yog qhov yuav tsum tau ua ntej rau lub illuminance meter.
