Lub hauv paus ntsiab lus ntawm digital illuminance meter/photometer/intensity meter/light meter
Ib qho kev luam tawm optical fiber ntau illuminance meter yog ib qho khoom siv kho qhov muag rau kev ntsuas lub teeb ci thiab lub teeb ci ntuj. Nws daws qhov teeb meem ntawm kev ntsuas tsis tu ncua ntawm lub teeb siv thiab tsis siv neeg kaw.
Lub ntsuas hluav taws xob hluav taws xob hluav taws xob ultraviolet yog lub ntsuas ntsuas qhov muag. Nws yog tus cwj pwm los ntawm ob txoj kev kho qhov muag pom tau tsim los ntawm ob lub unidirectional cut-off optical lim thiab ob qhov zoo tib yam photoelectric receivers. Lub Circuit Court ib feem siv dual-path amplification, thiaj li hais tias tus nqi hluav taws xob ntawm qhov yuav tsum tau kuaj band yuav raug ntsuas kom raug. Kev txiav tawm astigmatism muaj zog heev. Cov lus teb spectral ntawm lub ntsuas hluav taws xob digital ua raws li CIE tus qauv ntawm International Illuminating Association. 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 ceev. Tsis siv neeg kho muaj nuj nqi rau xwm txheej lub teeb cosine lub kaum sab xis. Nyeem tus nqi xauv muaj nuj nqi. Tsis siv neeg kaw ua haujlwm hauv 30 feeb. Maximum thiab yam tsawg kawg nkaus ntsuas ntsuas muaj nuj nqi.
Nws yog tsim los ntawm lub teeb pom kev, lub tshuab hluav taws xob hloov pauv tsis siv neeg, lub kaw lus nkhaus, lub tshuab luam ntawv digital thiab ib qho khoom siv tam sim no digital. Cov ntaub ntawv kaw lus nkhaus siv cov txheej txheem kho qhov muag fiber ntau frictionless, thiab lub teeb pom kev yog lub lim dej thiab lub xiav silicon photocell. Cov muaj pes tsawg leeg ua rau pom spectrum teb nkhaus raws li tib neeg pom spectrum nkhaus tau teev tseg los ntawm International Commission on Illumination (CIE).
Lub hnab tshos hluav taws xob illuminance meter belongs rau kev ua haujlwm ntawm kev ntsuas lub teeb pom kev zoo thiab tsim nyog rau kev ntsuas lub teeb 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 muaj cov khoom siv hluav taws xob DC, qhov hloov hluav taws xob hloov hluav taws xob, hloov hluav taws xob, photoresistor, ntsuas hluav taws xob, A / D converter, decoder, tus tsav tsheb thiab cov khoom sib txuas hauv series. mus rau qhov kawg tso zis ntawm DC fais fab mov. . Cov qauv siv hluav taws xob zam kev siv lub taub hau photometric, thiab tsuas yog siv 3V roj teeb rau DC fais fab mov. Lub decoder, tso saib tsav tsheb thiab cov zaub tau muab tso rau ntawm daim npav sib xyaw ua ke, ua rau nws yooj yim hauv cov qauv, me me, yooj yim txav, thiab teb. Lwm yam
CNS5119 AA qib. Raws li peb txhua tus paub, qhov ci ntsa iab ntawm qhov illuminated nto yog cuam tshuam nrog qhov xwm txheej ntawm lub teeb ci. Ib yam li ntawd, thaum ntsuas nrog lub teeb ntsuas, qhov xwm txheej ntawm lub ntsuas ntsuas (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.
