Cov Lus Qhia Cuam Tshuam thiab ua haujlwm ntawm lub ntsiab cai ntawm lub moice meter
1. Illuminometer:
Ib tug kim heev, tseem hu ua ib tug kim heev li cas yog ib qho ntsuas tshwj xeeb rau kev ntsuas luminosity thiab ci ci. Nws yog ntsuas ntsuas qhov kev siv ntawm lub teeb (illuminance)
Nws yog qib uas ib qho khoom uas yog illuminated, uas yog, tus piv ntawm cov luminous flux tau txais nyob rau ntawm cov khoom mus rau thaj chaw thaj chaw. Motuminance Meter yog feem ntau muaj ntawm selenium lossis silicon photovoltaic thiab ib metre microampere metre.
2. Kev Ntsuas Cov Ntsiab Cai:
Lub xov tooj photovolticic yog ib qho yees duab tiv thaiv uas tau hloov lub teeb lub zog rau hauv hluav taws xob. Thaum lub teeb muaj xwm txheej nyob saum npoo ntawm Selenium lub teeb cell, qhov teeb meem ntawm lub teeb saws selenium txheej 2 thiab tsim cov nyhuv hlau ua yeeb yaj kiab ntawm lub interface. Qhov ntau ntawm cov luam tawm photocrurrent yog ib feem yog ib feem ntawm kev pom ntawm qhov chaw ntawm lub photovoltaic cell tau txais lub teeb ci. Txij ntawm no, yog tias muaj kev sib txuas sab nraud, thiab tus nqi tam sim no yuav qhia nyob rau ntawm cov microoampere meter nrog cov lux (LX) raws li qhov ntsuas. Qhov ntau ntawm cov duab ntawm cov duab ntawm cov duab ntawm lub zog ntawm lub zog ntawm qhov xwm txheej teeb. Qhov ntsuas Illuminance muaj lub iav ua haujlwm ntaus ntawv, yog li nws tuaj yeem ntsuas ob qho tib si loj thiab tsawg illuminance.
Hom tshuaj ntsuab meters: 1. Pom cov ntsuas huab: Qhov tsis yooj yim siv, qhov raug qis, tsis tshua muaj siv. 2. OptoelectRonic Mireuminance: feem ntau yog siv Selenium lub hnub ci cell Illuminance Illuminance Iricon Hnub Ci Medica Meter.
Txheej txheem cej luam ntawm Illuminometer
Motenuminance 'meter' yog ib qho kev sim kho qhov muag tau siv los ntsuas qhov kev siv ntawm cov khoom siv thiab lub teeb ntuj. Nws daws cov teeb meem ntawm kev ntsuas tas mus li ntawm qhov kev siv lub teeb thiab sau cia tsis zoo no. Nws muaj ib lub teeb ntes, ib yam tsis siv neeg hloov kho Circuit Coh Amplifier Circuit Court, ib qho kev nkhaus teev cia, thiab ntaus ntawv digital digital digital. Cov ntaubntawv nkhaus cov ntaubntawv povthawj siv txoj cai sib dhos kom zoo nkauj uas siv rau cov neeg lim dej uas pom tau tias muaj cov neeg lim dej hauv lub teeb meem Lub hnab tshos hluav taws xob hluav taws xob Illuminance belongance ntsuas ntsuas kev ntsuas tshuab thiab haum rau ntsuas qhov hluav taws xob hauv kev ua liaj ua teb txhua hnub, thiab sab nraum zoov. Nws siv cov photoresistors raws li cov photiSelectric hloov dua tshiab thiab muaj cov khoom siv hluav taws xob dC. Qhov voltage concener, hloov, ntsuas hluav taws xob, a / d converter, thiab cov tsav tsheb, thiab cov tsav tsheb ua ntu zus los ntawm cov zis siv DC. Qauv hluav taws xob no kom tsis txhob siv lub taub hau photometric, thiab tsuas yog xav tau 3v roj teeb rau DC cov khoom siv fais fab. Lub decoder, zaub tsav tsheb, thiab cov zaub sib xyaw ua ke ntawm ib qho kev sib xyaw, kom yooj yim me, kom txav tau yooj yim, thiab muaj qhov zoo ntawm cov lus teb tshwj xeeb. A UV hluav taws xob, zwm rau cov twj ntsuas kho qhov muag. Nws cov yam ntxwv yog ob txoj kev sib tw txuas ntxiv ntawm ob lub chaw lim dej tsis zoo thiab ob lub photoelectric. Lub Circuit Court Qhov Adopts dual txoj kev progification, uas tuaj yeem ntsuas qhov hluav taws xob muaj txiaj ntsig ntawm cov kev xeem uas tsim nyog, thiab muaj lub teeb pom kev zoo nkauj.
