Ukushintsha koMhlanga kanye nezinzwa ze-Hall Effect
Izinzwa kazibuthe zisetshenziswa kukho konke kusukela ezimotweni kuya komakhalekhukhwini. Imuphi uzibuthe okufanele ngiwusebenzise ngenzwa yami kazibuthe? Ingabe kufanele ngisebenzise inzwa yomphumela weHholo noma inkinobho yomhlanga? Ngabe uzibuthe kufanele uqondiswe kanjani kwinzwa? Yikuphi ukubekezelelana okufanele ngikhathazeke ngakho? Funda kabanzi nge-K&J ehamba phambili yokucacisa inhlanganisela yenzwa kazibuthe.

Iyini I-Reed Switch?

Izinzwa ezimbili ze-Hall effect kanye neswishi yomhlanga. Iswishi yomhlanga ingakwesokudla.
I-reed switch iyiswishi kagesi esetshenziswa inkambu kazibuthe esetshenziswayo. Iqukethe ipheya yokuxhumana emhlangeni oyinsimbi emvilophini yengilazi engangeni moya. Oxhumana nabo ngokuvamile bayavuleka, akuthinti ukuthintana kukagesi. Iswishi icushiwe (ivaliwe) ngokuletha uzibuthe eduze kweswishi. Uma uzibuthe usukhishiwe, iswishi yomhlanga izobuyela endaweni yayo yokuqala.

Iyini inzwa ye-Hall Effect?
Inzwa ye-Hall effect iyi-transducer eshintsha amandla ayo okukhipha amandla ngokuphendula izinguquko endaweni kazibuthe. Ngandlela thize, izinzwa zomphumela weHholo ekugcineni zingakwazi ukwenza umsebenzi ofanayo njengokushintshwa komhlanga, kodwa zingabi nazingxenye ezihambayo. Kucabange njengengxenye yesimo esiqinile, elungele izinhlelo zokusebenza zedijithali.

Iyiphi kulezi zinzwa ezimbili elungele uhlelo lwakho lokusebenza incike ezintweni eziningi. Izinto zifaka izindleko, umumo kazibuthe, ububanzi befrikhwensi (amaswishi omhlanga ngokuvamile awasebenziseki ngaphezu kuka-10 kHz), ukugxuma kwesignali kanye nomklamo wokujikeleza komqondo ohlobene.

Magnet – Inzwa Orientation
Umehluko oyinhloko phakathi kokushintsha komhlanga nezinzwa ze-Hall effect ukuma okufanelekile okudingekayo ku-magnet ovulayo. Izinzwa zomphumela wehholo zisebenza uma kusetshenziswa inkambu kazibuthe encikene nenzwa yesimo esiqinile. Iningi libheka isigxobo sikazibuthe esiseningizimu ukuthi sibheke endaweni ekhonjisiwe kunzwa, kodwa hlola ishidi lokucaciswa kwenzwa yakho. Uma uphendulela umazibuthe emuva noma emaceleni, inzwa ngeke isebenze.

Amaswishi omhlanga awumshini onezingxenye ezihambayo. Iqukethe izintambo ezimbili ze-ferromagnetic ezihlukaniswe igebe elincane. Lapho kukhona amandla kazibuthe ahambisana nalezo zintambo, zizothintana zodwa, zithintane nogesi. Ngamanye amazwi, i-eksisi kazibuthe kazibuthe kufanele ihambisane ne-eksisi ende yokushintshwa komhlanga. U-Hamlin, umkhiqizi wamaswishi omhlanga, unenothi elihle kakhulu lesicelo ngale ndaba. Ihlanganisa imidwebo emihle ebonisa izindawo nemijikelezo lapho inzwa izosebenza khona.
I-Magnet Orientation efanele: Inzwa yomphumela weHholo (kwesokunxele) iqhathaniswa neswishi yomhlanga (kwesokudla)
Kumele kuqashelwe ukuthi ezinye izilungiselelo zingenzeka futhi zivame ukusetshenziswa. Isibonelo, izinzwa ze-Hall effect zikwazi ukubona izinsimbi zensimbi "zefeni" ephothayo. Izinsimbi zensimbi zefeni zidlula phakathi kukazibuthe omile kanye nenzwa emile. Uma insimbi iphakathi kokubili, inkambu kazibuthe iqondiswa kabusha kude nenzwa (ivinjiwe) futhi iswishi iyavuleka. Lapho insimbi isuka, uzibuthe uvala iswishi
