3. Vim li cas inert gas siv nyob rau hauv cov duab hluav taws xob transducers? Piav qhia: Inert gas ntawm siab 1 hli Hg yog sau rau hauv ib lub raj ntawm photoelectric transducer kom rhiab heev.
Qhov twg hauv qab no yog siv hauv photoelectric transducer?
Kev faib tawm ntawm Photoelectric Transducers: Cov photoelectric transducers tau muab faib ua cov hauv qab no. Photo-emissive cell hloov cov photons rau hauv hluav taws xob. Nws muaj cov anode rode thiab cathode phaj. Cov anode thiab cathode yog coated nrog cov duab-emissive khoom hu ua caesium antimony.
Lub hauv paus ntsiab lus tom qab photoelectric transducer yog dab tsi?
Kev piav qhia: Photoelectric transducers yog raws li lub hauv paus ntsiab lus ntawm hloov lub teeb lub zog rau hauv hluav taws xob. Qhov no yog ua los ntawm kev ua kom cov hluav taws xob poob rau ntawm cov khoom siv photosensitive thiab ntsuas cov hluav taws xob tam sim no thiaj li tsim tau nrog cov rhiab heev galvanometer ncaj qha lossis tom qab tsim cov amplification.
LDR hu ua dab tsi?
A photoresistor (tseem hu ua lub teeb-raws li resistor, LDR, lossis photo-conductive cell) yog ib qho khoom siv hluav taws xob uas txo qis kev ua haujlwm ntawm kev txais luminosity (lub teeb) nyob rau ntawm qhov chaw rhiab heev.
Qhov twg hauv qab no siv tau rau lub ntsuas hluav taws xob electromagnetic ?
Qhov twg hauv qab no siv tau rau covelectromagnetic flow meter? Nqe lus piav qhia: Electromagnetic flow meter tsis ua kom muaj kev cuam tshuam thiab tuaj yeem siv rau kev ntsuas hauv slurries.
