Uyini Umehluko Phakathi Kwe-Proximity Sensor ne-Photoelectric Sensor?

Emhlabeni wokuzenzakalelayo nezinhlelo zokusebenza zezimboni, izinzwa zidlala indima ebalulekile ekutholeni izinto, ukulinganisa amabanga, nokuqinisekisa ukusebenza okungenazihibe. Izinzwa ezimbili ezivame ukusetshenziswa izinzwa eziseduze nezinzwa ze-photoelectric. Nakuba zisebenzisa izinjongo ezifanayo, zisebenza ngezimiso ezihlukene futhi zifanele ukusetshenziswa okuhlukile. Ukuqonda umehluko wabo kungasiza ekukhetheni inzwa efanele yezidingo zakho.

 

Izinzwa Zokusondela

 

Izinzwa ze-Proximity zithola ubukhona bento ngaphandle kokuthintana ngokomzimba. Zihlukaniswa ngezinhlobo ezahlukahlukene ngokuya ngezimiso zazo zokusebenza, njengezinzwa ze-inductive, capacitive, magnetic, ne-ultrasonic.

 

Izinzwa ze-Inductive Proximity: Lezi zinzwa zisetshenziselwa ukuthola izinto zensimbi. Asebenza ngokukhiqiza inkambu ye-electromagnetic futhi athole izinguquko kulo mkhakha ezibangelwa ukuba khona kwensimbi.

 

Izinzwa Ze-Capacitive Proximity: Lezi zinzwa zingathola kokubili izinto zensimbi nezingezona ezensimbi. Basebenza ngokuzwa izinguquko kumthamo obangelwa ubukhona bento.

 

Izinzwa Zezibuthe Zezibuthe: Lezi zinzwa zithola izizinda kazibuthe futhi zivame ukusetshenziselwa ukuthola indawo yezinto kazibuthe.

 

I-Ultrasonic Proximity Sensors: Lezi zinzwa zisebenzisa amaza e-ultrasonic ukuze zibone izinto. Zisebenza ngempumelelo ekukaleni ibanga kanye nokubona izinhlobonhlobo zezinto.

 

Izinzuzo Zezinzwa Eziseduze:

 

Ukutholwa Ongathintana Naye: Izinzwa eziseduze zingathola izinto ngaphandle kokuthintana ngokomzimba, zinciphisa ukuguga nokukhala.

 

Ukuqina: Aqinile futhi angasebenza ezindaweni ezinokhahlo.

 

Ukuhlukahluka: Izinhlobo ezahlukene zezinzwa eziseduze zingathola izinto ezihlukahlukene, zizenze zibe nezinto ezihlukahlukene.

 

Izinzwa zikagesi wezithombe

 

Izinzwa ze-Photoelectric, ezaziwa nangokuthi ama-opto-isolator, zisebenzisa ukukhanya ukuze zithole ubukhona noma ukungabikho kwento. Aqukethe i-emitter (umthombo wokukhanya) kanye nesamukeli (umtshina wokukhanya). Kunezinhlobo ezintathu eziyinhloko zezinzwa ze-photoelectric: i-by-beam, i-retro-reflective, ne-diffuse.

 

Izinzwa ezidlula ibhimu: Lezi zinzwa zinamayunithi ahlukene e-emitter nawesamukeli. Inzwa ithola into lapho i-beam yokukhanya phakathi kwe-emitter nomamukeli iphazamiseka.

 

Izinzwa ze-Retro-reflective: Lezi zinzwa zine-emitter nomamukeli kuyunithi eyodwa futhi zisebenzisa isibonisi ukubuyisela ukukhanya kumamukeli. Into itholwa uma iphazamisa i-beam yokukhanya.

 

Izinzwa Zokusabalalisa: Lezi zinzwa zine-emitter nomamukeli kuyunithi eyodwa. Inzwa ithola into lapho ukukhanya okukhishiwe kuveza entweni futhi kubuyela kumamukeli.

 

Izinzuzo zezinzwa ze-Photoelectric:

 

Ibanga Lokutholwa Okude: Izinzwa zikagesi wesithombe zingakwazi ukubona izinto ezikude.

 

Ukunemba Okuphezulu: Zinikeza ukutholwa okunembayo futhi zifanele izinhlelo zokusebenza ezidinga ukunemba okuphezulu.

 

Ukuhlukahluka: Bangakwazi ukubona inhlobonhlobo yezinto ezisetshenziswayo nemibala.

 

Umehluko Obalulekile

 

Umgomo Wokusebenza:

 

Izinzwa ze-Proximity zisebenzisa izinkambu ze-electromagnetic, amandla, izinkundla kazibuthe, noma amaza e-ultrasonic.

 

Izinzwa zikagesi wesithombe zisebenzisa imishayo yokukhanya (i-infrared noma ukukhanya okubonakalayo).

 

Ibanga Lokuthola:

 

Izinzwa eziseduze zinebanga lokutholwa elifushane, ngokuvamile elifika kumasentimitha ambalwa.

 

Izinzwa zikagesi zikwazi ukubona izinto ezikude, ukusuka kumasentimitha ambalwa ukuya kumamitha ambalwa.

 

Ukutholwa Kwento:

 

Izinzwa ze-Proximity zilungele ukuthola izinto ezisansimbi nezingezona ezensimbi kuye ngohlobo.

 

Izinzwa zikagesi zikwazi ukubona cishe noma iyiphi into ngaphandle kwempahla, inqobo nje uma zingabonisa noma ziphazamise ukukhanya.

 

Izicelo:

 

Izinzwa ze-Proximity zivame ukusetshenziswa ezimbonini zokukhiqiza, zokupakisha, nezezimoto zokuzwa indawo, ukutholwa kwento, kanye nokuzwa izinga.

 

Izinzwa zikagesi wesithombe zisetshenziswa kakhulu kokuzenzakalelayo, amarobhothi, namasistimu okuphepha ukuze kutholwe into, ukukalwa kwebanga, nezinhlelo zokusebenza zokuphepha.

 

Sengiphetha, Kokubili izinzwa eziseduze nezinzwa zikagesi wezithombe zibalulekile ezinhlelweni zokusebenza zezimboni nezokuzenzakalelayo, ngayinye inikezela ngezinzuzo ezihlukile ngokusekelwe ezimisweni zazo zokusebenza. Izinzwa eziseduze zihamba phambili ebangeni elifushane, ukutholwa okuqinile kwezinto ezihlukahlukene, kuyilapho izinzwa ze-photoelectric zihlinzeka ngobude obude, ukutholakala kokunemba okuphezulu okufanele ezindaweni ezihlukahlukene. Ukuqonda umehluko wabo kuqinisekisa ukukhethwa kwenzwa efanele yezinhlelo zokusebenza ezithile, ukuthuthukisa ukusebenza kahle nokuthembeka ezinqubweni ezihlukahlukene zezimboni.
