Photoelectric firikwensin aiki ka'idar
Ainihin aikin na’urar Sensor ta Photoelectric ita ce, firikwensin yana fitar da hasken haske daga bangaren firikwensin da ake kira emitter, kuma wannan hasken yana tafiya zuwa bangaren firikwensin da ke karbar hasken da ake kira mai karba. Nau'o'in waɗannan na'urori masu auna firikwensin suna ɗaukar hasken haske ta hanyoyi daban-daban. Ko da kuwa nau'in firikwensin, yana aiki kamar firikwensin canza wutar lantarki.
Nau'in na'urori masu auna wutar lantarki
Ta hanyar-beam photoelectric firikwensin
Na farko, za mu yi magana game da Ta hanyar-Beam Photoelectric Sensor nau'in. Ta hanyar-Beam na'urori masu auna firikwensin suna da emitter da mai karɓa a cikin nasu bangaren daban.
Domin firikwensin Ta hanyar-Beam yayi aiki, emitter da mai karɓa dole ne a nuna juna kuma a daidaita su.
Lokacin da aka daidaita su kuma babu abin da ke toshe hasken, fitowar firikwensin zai kasance a kunne.
Idan kun sanya wani abu tsakanin emitter da mai karɓa don toshe hasken, fitowar firikwensin zai kashe.
Siginar fitarwa na firikwensin
Fitowar firikwensin shine sigina daga firikwensin zuwa PLC. Ka tuna, yana aiki kamar firikwensin canza wutar lantarki, yana kammala kewaye lokacin da aka kunna. Dangane da firikwensin, fitarwa na iya zama sigina mai kyau ko sigina mara kyau.
Nau'in siginar fitarwa na firikwensin da za ku yi amfani da shi ya dogara da irin nau'in katin shigar da PLC da firikwensin ya haɗa.
Misali,
– Idan firikwensin shinePNP, ma'ana yana da siginar fitarwa mai kyau, za a haɗa wayar fitarwa ta firikwensin zuwa anutsewakatin shigar da bayanai.
– Idan firikwensin shineNPNsiginar fitarwa ba ta da kyau kuma za a buƙaci a haɗa wayar da ake fitarwa zuwa atushenkatin shigar da bayanai.
Takaitawa
A cikin bita, ta karanta wannan labarin kun koya game da ainihin nau'ikan Sensors na Photoelectric guda uku:
- Ta hanyar Beam,
- Mai juya baya,
– Yaduwa.
Kun koyi cewa dukkanin firikwensin guda uku suna amfani da haske don gano abubuwa kuma dukkanin firikwensin uku suna da siginar fitarwa waɗanda ke haifar da shigarwar PLC.
Hakanan kun koyi game da nau'ikan ji daban-daban da wasu rashin amfanin kowane firikwensin.
