Sensor Hall

Ifuthe Hall sisiseko kusetyenziso lweeteknoloji ofanayo non-zoqhagamshelwano ukubhalisa kwisigaba of kelelo, intshukumo kunye ubucotha ukujikele- bezinto ferromagnetic.

Yintoni woluvo Hall, kunokwenzeka ukuba ukuqonda, ukuze baqonde kwiinkqubo isiphumo esivulekayo kuyo. Ngexesha sicatshulwa ngoku ngawo umzimba imbasa kwicala longitudinal xa mhlaba otsalayo kwenzeka ngokwezahlulo ekupheleni kwipleyiti kwicala ezinqamlezayo ukuya intshukumo yangoku, umahluko enokwenzeka yenziwe. Oku kubangelwa ngumthetho Lorentz, leyo umisela yokuba ngenxa yempembelelo mhlaba otsalayo tokonositeli bakholisa shift kungqameko nembasa. Umahluko ezinokubakho eliphuma kisekiyo ngqo ubukhulu imveliso kumda wesangqa ka amandla entsimini yangoku H • I.

Xa kungekho mhlaba otsalayo kwi wobhobhozayo electron lungenzeki Bill. Xa zibuthe Lorentz imikhosi ababandakanyekayo kokukhatywa electron kunye ababangela ukugoba trajectories zabo. Ezi imikhondo unobangela ukuqokelelana izityholo ezingalunganga kwelinye icala nembasa. Kwelinye icala kwipleyiti isebenza njengendawo ukuqokelelana intlawuliso uncompensated HIV. Uyondelelwano lwee- iintlawuliso phezu komhlaba ebusweni icala plate unobangela yentsimi yombane kwicala ezinqamlezayo, leyo kuthiwa intsimi Hall. Le nkqubo iqhubeka de yokugcina kwentlawulo de ukubonakala EMF ezinqamlezayo ngeke sigqibe bezimpi uzikise lo mhlaba otsalayo. Emva koko bakhwela imo inkqubo emileyo, apho electron ukusuka kwicala ngaxeshanye kunye kungqameko kwipleyiti, njengoko kungekho yentsimi ngemagnethi.

sensor Hall, ukwenza izinto

Le nkcazelo semiconductor kwe zincwadi Womenzi iHolo ukuba zenziwe, lophethe kufuneka nje phezulu, kodwa kancinci kangangoko lixhomekeke zentsulungeko lobushushu, eyaziwa ngokuba lomlingani Hall, neshukumayo ikhono abathwali. Kuba Ukukhethwa kwezinto semiconductor (ithagethi - ukwenza woluvo Hall) ukukhokela kwindawo yayo zokusetyenziswa.

Le lomlingani iHolo ichazwa yi imfuneko zokulinganisela of otsalayo induction asendle, ngoku ngalo isampuli kunye ukumisa balo babulingana nesandla. Ulwazi yexabiso lomlingani Hall, kunokwenzeka ukuba ukumisela lwee- abathwali elugcinweni umzimba kwipleyiti, nto leyo bomzimba ngokomlinganiselo imveliso inani kwiHolo intlawulo electron.

Semiconductors zidla ayisetyenziswa phambi Uhanjiso elektroniki ngenxa yokuba ukuba aphezulu kakhulu carrier ukuhamba ngaphandle kwezo semiconductors ebonisa p-uhlobo conductivity. Qiniseka ukwazi ukuba iimpawu ezibonakalayo zemathiriyeli semiconductor lunokuxhomekeka kutshintsho ezibalulekileyo, ngokuxhomekeke kuhlobo nokuba zingaphi ubumdaka iya kuqaliswa kuzo.

Hall woluvo nobuchwepheshe ukuze lemveliso

Ukuvelisa i nesonkana esisicaba semiconductor ukuze zisetyenziswe kule woluvo Hall kuba ngolu hlobo lulandelayo:

1. Hall wasela akhazimlayo ipleyiti imilo zinqwenelekayo oononye bar njengekristale.

2. Fumana kwipleyiti Hall ukuya zeendawana ngokuthi wokutshiza oomaleko thinnest izinto semiconductor.

abenzi Hall Scope

Ukusebenzisa abenzi boluvo Hall yomgama ezisasazwa kwi ifomu:

- ezibizwa ngoku;

- actuators ngesantya bume;

- iziphaluka zolawulo kunye nokukhuselwa motor;

- abenzi isikhundla;

- abenzi flow;

- Motors brushless DC ;

- potentiometers licwecwe;

- isivamvo ukujikeleza engile;

- detectors imizimba ferromagnetic;

- abenzi lokungcangcazela;

- tachometer.

Ulwazi ezibekwe nqaku liza kuba luncedo ukuba umfundi xa kuthe kwingxoxo yintoni zincwadi Womenzi Hall.
