Cov ntsiab lus ntawm Digital Luxmeter / Intensity Meter / Lub Teeb Quantity Meter
Lub tshuab luam ntawv tsis siv neeg kho qhov muag fiber ntau illuminance meter yog qhov ntsuas qhov muag rau kev ntsuas qhov siv ntawm lub teeb ci thiab lub teeb ntuj. Nws daws qhov teeb meem ntawm kev ntsuas tsis tu ncua ntawm lub teeb siv thiab tsis siv neeg kaw.
Cov qauv siv hluav taws xob cuam tshuam nrog lub ntsuas hluav taws xob ultraviolet illuminance meter, uas yog cov cuab yeej ntsuas qhov muag. Nws yog tus cwj pwm los ntawm ob txoj hauv kev txiav tawm qhov muag pom thiab ob qhov zoo tib yam photoelectric receivers los tsim ib lub teeb pom kev zoo dua. 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 yuav raug ntsuas kom raug, thiab lwm yam Lub astigmatism txiav-tawm yog muaj zog heev. Cov lus teb spectral ntawm lub ntsuas hluav taws xob digital ua raws li CIE tus qauv ntawm International Association of Lighting. Peak xauv muaj nuj nqi. Kev ntsuas ntau yam 0 txog 40K Lux (0 txog 40K fc). Tus nqi sib piv muaj nuj nqi. High precision thiab ceev teb. Teeb meem lub teeb cosine kaum tsis siv neeg kho muaj nuj nqi. Nyeem xauv muaj nuj nqi. 30 feeb tsis siv neeg kaw muaj nuj nqi. Qhov siab tshaj plaws thiab qhov ntsuas qhov tsawg kawg nkaus.
Nws yog tsim los ntawm photodetector, ib qho tsis siv neeg iav hloov amplifier Circuit Court, ib tug nkhaus kaw cov cuab yeej, lub tshuab luam ntawv digital thiab ib qho instantaneous digital zaub ntaus ntawv. Lub nkhaus kaw cov cuab yeej siv cov txheej txheem kho qhov muag fiber ntau frictionless, thiab photodetector yog lim thiab xiav silicon photocell. Kev sib xyaw ua ke, kom pom qhov pom spectral teb nkhaus ua raws li tib neeg kev pom spectrum nkhaus uas tau teev tseg los ntawm International Commission on Illumination (CIE).
Lub hnab tshos hluav taws xob illuminance meter belongs rau kev ntsuas kev ntsuas teeb pom kev zoo thiab tsim nyog rau kev ntsuas lub teeb pom kev thaum lub sijhawm ua liaj ua teb, lub neej txhua hnub, thiab mus ncig sab nraud. Nws siv lub photoresistor li photoelectric hloov dua siab tshiab ntaus ntawv, uas muaj ib tug DC fais fab mov, thiab yog sib txuas nyob rau hauv series nrog ib tug voltage converter Circuit Court, ib tug hloov, ib tug photoresistor, ib tug xeem Circuit Court, ib tug A / D converter, ib tug decoder, ib tug zaub. tsav tsheb thiab ib qho zaub ntawm qhov tso zis kawg ntawm DC fais fab mov. . Tus qauv siv hluav taws xob zam kev siv lub taub hau photometric, thiab DC fais fab mov tsuas yog xav tau 3V roj teeb. Lub decoder, cov zaub 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, yooj yim txav, thiab rhiab hauv cov lus teb. Lwm yam
CNS5119 Chav Kawm AA. 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.
