Sensor retro-reflective e nang le polarized reflector e fanoa ka seo ho thoeng ke polarization filter. Sefefo sena se etsa bonnete ba hore khanya e nang le wavelength e fanoeng e ea bonahala, 'me likarolo tse ling ha li bonahale. Ka ho sebelisa tšobotsi ena, ho bonahatsoa feela leseli le nang le bolelele ba maqhubu a khanya e hlahisoang.
Molao-motheo o sebetsang oa sensor ea Photoelectric
Ts'ebetso ea mantlha ea Sensor ea Photoelectric ke, kutlo e romela leseli ho tsoa karolong ea sensor e bitsoang emitter, 'me leseli lena le ea karolong ea sensor e bokellang leseli le bitsoang moamoheli. Mefuta e fapaneng ea li-sensor tsena e sebetsana le khanya ea leseli ka mekhoa e fapaneng. Ho sa tsotelehe mofuta oa sensor, e sebetsa joalo ka sensor ea photoelectric switch.
Mefuta ea li-sensor tsa photoelectric
Sensor ea motlakase ea motlakase ka borokho
Taba ea pele, re tla bua ka mofuta oa Through-Beam Photoelectric Sensor. Li-sensor tsa Through-Beam li na le emitter le moamoheli karolong ea tsona e arohaneng.
Hore sensor ea Through-Beam e sebetse, emitter le moamoheli li tlameha ho supana le ho hokahanngoa.
Ha li tsamaisana 'me ha ho letho le thibelang leseli, tlhahiso ea sensor e tla ba teng.
Haeba u beha ho hong pakeng tsa emitter le moamoheli ho thibela leseli, tlhahiso ea sensor e tla tima.
Letšoao la tlhahiso ea sensor
Sephetho sa sensor ke lets'oao le tsoang ho sensor ho ea ho PLC. Hopola, e sebetsa joalo ka sensor ea photoelectric switch, e tlatsang potoloho ha e kentsoe. Ho itšetlehile ka sensor, tlhahiso e ka ba pontšo e ntle kapa pontšo e mpe.
Mofuta oa lets'oao la sensor leo u tla le sebelisa le itšetlehile ka mofuta oa karete ea ho kenya ea PLC eo sensor e hokahaneng le eona.
Ka mohlala,
- Haeba sensor e tengPNP, ho bolelang hore e na le pontšo e ntle ea tlhahiso, mohala oa motlakase oa sensor o tla tlameha ho hokahanngoa le aho tebakarete ea ho kenya.
- Haeba sensor e tengNPNlets'oao la tlhahiso le mpe mme terata ea tlhahiso e tla hloka ho hokahana le aho fumanakarete ea ho kenya.
Kakaretso
Ha u hlahloba, ka ho bala sengoloa sena u ithutile ka mefuta e meraro ea mantlha ea li-sensors tsa Photoelectric:
- Ka Beam,
- Retroreflective,
– E arotsoe.
U ithutile hore li-sensor tsena tse tharo li sebelisa leseli ho bona lintho mme li-sensor tse tharo li na le matšoao a hlahisang tlhahiso ea PLC.
U boetse u ithutile ka mefuta e fapaneng ea li-sensing le tse ling tsa mefokolo ea sensor ka 'ngoe.
