I-retro-reflective sensor kunye ne-polarized reflector inikwe into ebizwa ngokuba yi-polarization filter. Esi sihluzo siqinisekisa ukuba ukukhanya okunobude obunikiweyo bubonakalisiwe kwaye obunye bobude bobude abubonakali. Ngokusebenzisa olu phawu, kuphela kukukhanya okunobude bokukhanya okukhutshiweyo kubonakaliswa.
Umgaqo womsebenzi we-photoelectric sensor
Umsebenzi osisiseko we-Photoelectric Sensor kukuba, i-sensor ithumela i-beam yokukhanya ukusuka kwindawo ye-sensor ebizwa ngokuba yi-emitter, kwaye lo msebe wokukhanya uhamba ukuya kwindawo ye-sensor eqokelela ukukhanya okubizwa ngokuba yi-receiver. Iindidi ezahlukeneyo zezi zivamvo ziphatha umqadi wokukhanya ngeendlela ezahlukeneyo. Kungakhathaliseki ukuba luhlobo luni loluvo, lusebenza njenge-sensor ye-photoelectric switch.
Iindidi zeenzwa zefoto zombane
Nge-beam photoelectric sensor
Okokuqala, siza kuthetha malunga nohlobo lwe-Brough-Beam Photoelectric Sensor. Abenzi boluvo nge-Beam bane-emitter kunye nomamkeli kwicandelo labo elahlukileyo.
Ukuze i-sensor ye-Brough-Beam isebenze, i-emitter kunye ne-receiver kufuneka zikhonjwe omnye komnye kwaye zilungelelaniswe.
Xa zilungelelaniswa kwaye akukho nto ithintela ukukhanya, imveliso yenzwa iya kuvuleka.
Ukuba ubeka into phakathi kwe-emitter kunye ne-receiver ukuvimba ukukhanya, imveliso yenzwa iya kucima.
Umqondiso wesiphumo senzwa
Isiphumo soluvo luphawu olusuka kwi-sensor ukuya kwi-PLC. Khumbula, isebenza njenge-sensor ye-photoelectric switch, ukugqiba isiphaluka xa ivuliwe. Ngokuxhomekeke kwinzwa, umphumo unokuba ngumqondiso ochanekileyo okanye umqondiso ongalunganga.
Uhlobo lomqondiso wokuphuma koluvo oza kulisebenzisa luxhomekeke kuluphi uhlobo lwekhadi lokufaka i-PLC inzwa eqhagamshelwe kulo.
Umzekelo,
- Ukuba inzwaPNP, oku kuthetha ukuba inomqondiso wesiphumo esilungileyo, ucingo oluphuma kwinzwa kuya kufuneka ludityaniswe kwiUkutshonaikhadi lokufaka.
- Ukuba inzwaNPNuphawu lwemveliso lubi kwaye ucingo lwemveliso luya kufuna ukudityaniswa kwi-aukufumanaikhadi lokufaka.
Isishwankathelo
Uphononongo, ngokufunda eli nqaku ufunde malunga neentlobo ezintathu ezisisiseko zeeSensors zeFotoelectric:
-Nge-Beam,
-Ukubuyela umva,
– Usasazekile.
Ufundile ukuba zontathu izinzwa zisebenzisa ukukhanya ukubona izinto kwaye zontathu izinzwa zinemiqondiso ebangela igalelo lePLC.
Ufunde kwakhona malunga noluhlu olwahlukeneyo lwezivamvo kunye nokunye okungeloncedo kwinzwa nganye.
