Dab tsi yog qhov yuav tsum tau siv lub teeb ntsuas ntsuas?
1. Visual illuminance meter: siv tsis yooj yim, tsis raug, tsis tshua siv
2. Photoelectric illuminance meter: Feem ntau siv selenium photovoltaic illuminance meter thiab silicon photovoltaic illuminance meter
Muaj pes tsawg leeg thiab kev siv yuav tsum tau ntawm photocell illuminance meter:
1. Composition: microammeter, hloov pob qhov rooj, xoom taw tes hloov kho, davhlau ya nyob twg, photocell, V (λ) kho lim, thiab lwm yam.
Feem ntau siv selenium (Se) photovoltaic hlwb los yog silicon (Si) photovoltaic hlwb illuminance meters, los yog lux meters
2. Cov kev cai siv:
Lub illuminance meter sojntsuam yog ua los ntawm iav, uas yooj yim rau tawg thiab tawg. Thaum siv tib lub sijhawm, cov nyhuv dej tsis zoo yog qhov tsis zoo.
① Photovoltaic hlwb yuav tsum siv selenium (Se) photovoltaic hlwb los yog silicon (Si) photovoltaic hlwb nrog linearity zoo; lawv tseem muaj peev xwm tswj tau zoo stability thiab muaj siab rhiab heev tom qab ua haujlwm ntev; Thaum E yog siab, siv cov cell photovoltaic nrog siab sab hauv tsis kam, uas muaj tsawg rhiab heev thiab zoo linearity. , tsis yooj yim puas los ntawm lub teeb pom kev zoo
② Muaj V (λ) kho lim sab hauv, uas yog tsim rau illumination ntawm lub teeb qhov chaw nrog txawv xim kub thiab muaj me me yuam kev.
③Ntxiv lub cosine lub kaum sab xis compensator (opalescent iav los yog yas dawb) nyob rau hauv pem hauv ntej ntawm lub photovoltaic cell. Yog vim li cas yog tias thaum lub kaum sab xis tshwm sim loj, lub cell photovoltaic deviates los ntawm txoj cai cosine.
④ Lub ntsuas hluav taws xob yuav tsum ua haujlwm ntawm chav tsev kub lossis ze rau chav sov (photocell drift hloov nrog kub hloov)
