Mayelana Nezinzwa Zomhlanga

Mayelana Nezinzwa Zomhlanga
Izinzwa zomhlanga zisebenzisa uzibuthe noma uzibuthe kagesi ukuze zenze indawo kazibuthe evula noma evala iswishi yomhlanga ngaphakathi kwenzwa. Le divayisi elula ngokukhohlisayo ilawula ngokuthembekile amasekhethi ezinhlobonhlobo zezimpahla zezimboni nezohwebo.

Kulesi sihloko, sizoxoxa ngokuthi izinzwa zomhlanga zisebenza kanjani, izinhlobo ezahlukene ezitholakalayo, umehluko phakathi kwezinzwa ze-Hall Effect nezinzwa zomhlanga, kanye nezinzuzo ezibalulekile zezinzwa zomhlanga. Sizophinde sinikeze umbono wezimboni ezisebenzisa izinzwa zomhlanga nokuthi iMagneLink ingakusiza kanjani ukuthi udale amaswishi omhlanga angokwezifiso ephrojekthi yakho elandelayo yokukhiqiza.

Zisebenza Kanjani Izinzwa Zomhlanga?
Iswishi yomhlanga ipheya lezinto ezithinta ugesi ezidala isekethe evaliwe lapho zithinta kanye nesekhethi evulekile lapho ihlukaniswa. Amaswishi omhlanga akha isisekelo senzwa yomhlanga. Izinzwa zomhlanga zineswishi kanye nomazibuthe onika amandla ukuvula nokuvala abathintwayo. Lolu hlelo luqukethwe ngaphakathi kwesitsha esivalwe nge-hermetically.

Kunezinhlobo ezintathu zezinzwa zomhlanga: izinzwa zomhlanga ezivamise ukuvuleka, izinzwa zomhlanga ezivamise ukuvaleka, nezinzwa zomhlanga ezihuqayo. Zontathu izinhlobo zingasebenzisa uzibuthe wendabuko noma uzibuthe kagesi, futhi ngayinye incike ezindleleni ezihluke kancane zokusebenzisa.

Ngokuvamile Vula izinzwa Reed
Njengoba igama lisho, lezi zinzwa zomhlanga zisendaweni evulekile (enqanyuliwe) ngokuzenzakalelayo. Uma uzibuthe kunzwa ifinyelela kuswishi yomhlanga, iphendulela ukuxhumana ngakunye kube izigxobo ezishajwe ngokuphambene. Lokho kukhangana okusha phakathi kokuxhumana okubili kubaphoqa ndawonye ukuvala isekethe. Amadivayisi anezinzwa zomhlanga ovulekile achitha isikhathi esiningi ecishiwe ngaphandle uma uzibuthe esebenza ngenhloso.

Izinzwa Zomhlanga Ezivamise Ukuvala
Ngokuphambene, izinzwa zomhlanga ezivaliwe ngokuvamile zenza amasekhethi avaliwe njengendawo yawo emisiwe. Kuze kube yilapho uzibuthe eqala ukukhanga okuthile lapho isishishi somhlanga sinqamula futhi siphule uxhumo lwesekethe. Ugesi ugeleza ngenzwa yomhlanga evamise ukuvaleka kuze kube yilapho uzibuthe ephoqa izixhumi zokushintshwa komhlanga ezimbili ukwabelana nge-polarity kazibuthe efanayo, ephoqa izingxenye ezimbili ukuba zihlukane.

Lolu hlobo lwenzwa yomhlanga luhlanganisa ukusebenza kwakho kokubili okuvamise ukuvaleka nezinzwa zomhlanga ezivame ukuvuleka. Kunokuzenzakalela esimweni esinamandla noma esingenawo amandla, izinzwa zomhlanga ezixhumeneyo zihlala endaweni yazo yokugcina kuze kube yilapho kuphoqelelwa ushintsho kuzo. Uma uzibuthe kagesi uphoqa iswishi endaweni evulekile, iswishi izohlala ivuliwe kuze kube yilapho uzibuthe kagesi amandla futhi yenze isekethe ivale, ngokufanayo. Amaphuzu okusebenza nawokukhulula weswishi adala i-hysteresis yemvelo, ebamba umhlanga endaweni.
