Dab tsi yog photoelectric hloov sensors thiab qhov sib thooj keyboards, thiab lawv siv hauv kev lag luam dab tsi?
Photoelectric Hloov Sensor yog ib hom sensor uas siv cov nyhuv photoelectric los ntes. Nws ua haujlwm los ntawm kev xa tawm ib lub teeb ntawm lub teeb thiab xyuas seb lub beam puas raug thaiv los txiav txim qhov muaj thiab lub xeev ntawm cov khoom. Cov txheej txheem tshwj xeeb yog raws li hauv qab no: 1. Emission beam: Lub sensor emits ib lub teeb ntawm lub teeb. 2. Tau txais lub teeb liab: Thaum ib yam khoom nkag mus rau hauv txoj kev teeb, lub teeb yuav raug thaiv los yog tawg, thiab lub teeb liab tau txais los ntawm lub sensor yuav hloov. 3. Kev ua cov teeb liab: Lub sensor ua cov teeb liab tau txais los txiav txim seb cov khoom puas muaj, txoj hauj lwm thiab cov xwm txheej ntawm cov khoom thiab lwm yam ntaub ntawv. Raws li txoj kev tshawb nrhiav, nws tuaj yeem muab faib ua hom diffuse, hom reflector, hom iav reflection, trough type photoelectric hloov thiab. Optical fiber ntau photoelectric hloov
Hom antibeam muaj ib lub transmitter thiab receiver, uas yog sib cais los ntawm ib leeg nyob rau hauv cov qauv, thiab yuav tsim ib tug switching teeb liab hloov thaum lub beam cuam tshuam, feem ntau nyob rau hauv ib txoj kev uas photoelectric keyboards nyob rau tib lub axis tuaj yeem sib cais ntawm ib leeg mus txog 50 meters.
Photoelectric hloov sensor feem ntau yog tsim nyog rau kev xav tau los txiav txim siab qhov muaj nyob ntawm cov khoom, qhov chaw thiab cov xwm txheej ntawm lub sijhawm, xws li cov cuab yeej siv tshuab tsis siv neeg hauv kev tshawb nrhiav cov khoom, cov kab sib dhos hauv cov khoom suav, vending tshuab hauv cov khoom nrhiav pom, tab sis kuj tau siv dav hauv kev saib xyuas kev ruaj ntseg, teeb pom kev zoo, cov khoom siv game thiab lwm yam.
