Lub photoelectric sensor yog ib qho cuab yeej uas hloov lub teeb liab mus rau hauv hluav taws xob cov cim, thiab nws cov ntsiab lus ua haujlwm yog ua raws li cov teebmeem ntawm photoelectric. Lub luag haujlwm ntawm photoelectric txhais tau hais tias thaum lub teeb irradiates qee yam tshuaj, cov hluav taws xob ntawm cov khoom nqus lub zog ntawm photon, thiab cov hluav taws xob cuam tshuam tshwm sim. Raws li cov xwm txheej sib txawv ntawm cov nyhuv photoelectric, cov nyhuv photoelectric tuaj yeem muab faib ua peb pawg: cov nyhuv sab nrauv photoelectric, sab hauv photoelectric effect thiab cov nyhuv photovoltaic.
Cov ntsuas hluav taws xob photoelectric sensor yog tswj los ntawm kev hloov pauv ntawm lub teeb hloov mus rau kev hloov pauv ntawm lub teeb liab hluav taws xob. Ua ntej, lub tshuab xa tawm ntawm lub hom phiaj thiab emits lub teeb ci tsis muaj kev cuam tshuam; thib ob, lub txais tau txais lub teeb ci tso tawm los ntawm cov khoom xa tawm thiab hloov mus rau hauv hluav taws xob teeb liab; Thaum kawg, kuaj pom lub cim hluav taws xob pom cov hluav taws xob cov paib tsim tawm los ntawm tus txais thiab tsuas yog khaws lub teeb liab uas siv tau.
Photoelectric sensor yog lub ntsuas nrog cov khoom siv photoelectric uas yog lub hloov dua siab tshiab. Nws tuaj yeem siv los tshawb txog hluav taws xob tsis yog hluav taws xob uas ua rau ncaj qha kev hloov pauv ntawm lub teeb, xws li kev siv lub teeb, lub teeb nrig, qhov ntsuas qhov ntsuas kub, ntsuas roj tsom, thiab lwm yam; nws kuj tseem siv tau los kuaj txog lwm yam tsis yog hluav taws xob uas tuaj yeem hloov mus rau kev hloov pauv hauv lub teeb. Kev siv hluav taws xob, xws li feem ntawm lub cheeb, qhov saum npoo ntawm tawv nqaij, lub nraub qaum, hloov chaw, kev co, ceev, nrawm nrawm, thiab txheeb xyuas cov khoom duab thiab cov xwm txheej ua haujlwm.
Xyoo tsis ntev los no, nws tau siv dav hauv laser riam phom thiab nyeem tshuab ntsuas hluav taws xob, tshuab ntsuas pa luam yeeb, lub tshuab kuaj kab cim, cov khoom ntsuas, cov khoom siv hluav taws xob, photoelectric pa hluav taws, ntsuas ceev, thiab daim ntawv thov ntawm photocells hauv photoelectric kuaj thiab kev tswj tsis siv neeg.
