Lub retro-reflective sensor nrog polarized reflector yog muab nrog lub npe hu ua polarization lim. Cov lim dej no ua kom paub tseeb tias lub teeb nrog lub teeb ci uas tau muab lub teeb pom kev zoo thiab qhov seem ntawm lub wavelengths tsis yog. Los ntawm kev siv tus cwj pwm no, tsuas yog lub teeb nrog lub wavelength ntawm lub teeb emitted yog reflected.
Photoelectric sensor ua haujlwm txoj cai
Lub luag haujlwm tseem ceeb ntawm Photoelectric Sensor yog, lub sensor xa tawm lub teeb ci los ntawm ib feem ntawm lub sensor hu ua lub emitter, thiab lub teeb lub teeb no mus rau ib feem ntawm lub sensor uas sau lub teeb hu ua receiver. Ntau hom ntawm cov sensors no tswj lub teeb beam nyob rau hauv ntau txoj kev. Txawm hais tias hom sensor, nws ua zoo li photoelectric hloov sensor.
Hom photoelectric sensors
Hla-beam photoelectric sensor
Ua ntej, peb yuav tham txog Kev Hla-Beam Photoelectric Sensor hom. Los ntawm-Beam sensors muaj cov emitter thiab cov receiver nyob rau hauv lawv tus kheej cov khoom sib cais.
Txhawm rau kom dhau-Beam sensor ua haujlwm, lub emitter thiab receiver yuav tsum tau taw qhia ntawm ib leeg thiab ua raws.
Thaum lawv ua raws thiab tsis muaj dab tsi thaiv lub teeb, cov zis ntawm lub sensor yuav nyob rau.
Yog tias koj muab ib yam dab tsi ntawm lub emitter thiab receiver los thaiv lub teeb, cov zis ntawm lub sensor yuav tua.
Sensor tso zis teeb liab
Lub sensor tso zis yog lub teeb liab los ntawm lub sensor mus rau PLC. Nco ntsoov, nws ua zoo li photoelectric hloov sensor, ua tiav lub voj voog thaum qhib. Nyob ntawm lub sensor, cov zis tuaj yeem yog lub teeb liab zoo lossis tsis zoo.
Hom kev tawm suab sensor koj yuav siv nyob ntawm seb hom PLC input card lub sensor txuas nrog.
Piv txwv li,
- Yog hais tias lub sensor yogPNP, txhais tau hais tias nws muaj ib tug zoo tso zis teeb liab, lub sensor lub tso zis hlau yuav tsum tau txuas nrog atogdaim npav nkag.
- Yog hais tias lub sensor yogNPNlub teeb liab tso zis tsis zoo thiab cov zis xaim yuav tsum tau txuas nrog akev nrhiavdaim npav nkag.
Cov ntsiab lus
Hauv kev tshuaj xyuas, los ntawm kev nyeem cov kab lus no koj tau kawm txog peb yam yooj yim ntawm Photoelectric Sensors:
- Hla-Beam,
- Retroreflective,
-Diffused.
Koj tau kawm tias tag nrho peb lub sensors siv lub teeb los ntes cov khoom thiab tag nrho peb lub sensors muaj cov teeb liab tso tawm uas ua rau PLC cov tswv yim.
Koj kuj tau kawm txog qhov sib txawv ntawm qhov sib txawv thiab qee qhov tsis zoo ntawm txhua lub sensor.
