Lub qhov hloov pauv hlau nplaum yog ib lub cuab yeej hluav taws xob uas ua haujlwm tau ntau yam uas teb rau cov teb hlau nplaum. Txij li Hall Effect mus rau cov qhov hloov pauv reed, tshawb nrhiav lawv cov haujlwm, hom, thiab ntau yam kev siv.

Lub Magnetic Switch yog dab tsi?

Ib qho kev hloov pauv sib nqus yog ib lub cuab yeej hluav taws xob uas ua haujlwm los ntawm kev teb rau qhov muaj lub zog sib nqus. Nws ua haujlwm los ntawm kev kaw lossis qhib nws cov kev sib cuag raws li lub zog ntawm lub zog sib nqus. Tshwj xeeb, lub qhov hloov tseem kaw (rau) thaum raug rau lub zog sib nqus thiab qhib (tawm) thaum lub zog raug tshem tawm.

Lub Magnetic Switch Ua Haujlwm Li Cas?

Ib lub qhov hloov pauv hlau nplaum ua haujlwm los ntawm kev sib cuam tshuam ntawm ob lub ntsiab lus tseem ceeb: lub tshuab hluav taws xob sib nqus thiab lub qhov hloov pauv reed. Lub tshuab hluav taws xob sib nqus yog lub hlau nplaum me me uas nyob hauv lub thawv tiv thaiv, thaum lub qhov hloov pauv reed muaj lub raj iav uas muaj ob lub qhov sib txuas hlau. Thaum lub tshuab hluav taws xob sib nqus los ze rau lub qhov hloov pauv reed, nws lub zog sib nqus cuam tshuam rau cov qhov sib txuas hlau, ua rau lawv txuas thiab kaw lub voj voog lossis cais thiab qhib nws.

Lub hauv paus ntsiab lus tseem ceeb yog kev txhawb thiab tshem tawm lub zog ntawm lub kauj hluav taws xob. Thaum hluav taws xob ntws los ntawm lub kauj, nws tsim ib lub zog sib nqus uas rub cov hlau nplaum ze lossis cov khoom hlau. Thaum lub zog tam sim no nres, lub zog sib nqus yuav tawg, tso tawm lub zog khaws cia. Cov txheej txheem no zoo ib yam li kev ncab thiab tso tawm ib txoj hlua roj hmab, qhov twg lub zog raug tso tawm sai sai.

Cov qhov hloov pauv sib nqus muaj ntau yam siv tau thiab tiv taus cov yam ntxwv ib puag ncig xws li dej, roj, dej khov, hmoov av, thiab ntau ntxiv. Piv txwv li, cov qhov hloov pauv hluav taws xob, Hall sensors, thiab cov qhov hloov pauv reed. Lawv lub zog thiab kev ywj pheej ua rau lawv haum rau ntau yam kev siv hauv kev lag luam thiab tsev neeg.

Hom Kev Hloov Pauv Sib Nqus

Cov qhov hloov pauv sib nqus muaj ntau hom, txhua hom tsim rau cov kev siv tshwj xeeb thiab cov ntsiab cai ua haujlwm. Hauv qab no yog cov hom tseem ceeb ntawm cov qhov hloov pauv sib nqus:

Cov Kev Hloov Pauv Hall

Cov qhov hloov Hall Effect yog cov khoom siv semiconductor uas ua haujlwm yam tsis muaj kev sib cuag, ua rau lawv ruaj khov heev thiab tiv taus kev hnav lossis kev poob siab. Cov qhov hloov no feem ntau siv ua cov qhov hloov txwv hauv cov ntawv thov xws li cov tshuab nqa, cov khoom siv hauv Hoobkas, thiab tsheb.

Cov hloov pauv Hall Effect muab kev ywj pheej hauv kev tsim nrog cov kev xaiv xws li Unipolar (nrhiav ib lub ncej sib nqus) lossis Omnipolar (nrhiav ob qho tib si North thiab South poles). Lawv qhov kev rhiab heev ntawm lub zog sib nqus nyob ntawm qhov hluav taws xob siv thiab hom teb sib nqus tsim, uas tso cai rau lawv kom raug kho rau ntau yam kev xav tau ntawm daim ntawv thov.

Cov Hloov Reed

Cov reed switches muaj kev nkag siab zoo rau cov teb magnetic thiab paub txog lawv cov nqi tsim nyog thiab kev hloov pauv tau. Cov switches no siv dav hauv kev siv qhov sib ze lossis txwv kev siv, suav nrog xov tooj ntawm tes, qhov rooj khoom siv hauv tsev, lub tswb ceeb toom kev ruaj ntseg, tshuab hnyav, thiab qhov rooj tsheb.

Cov reed switches tuaj yeem hloov kho raws li cov yam xws li qhov loj ntawm reed, cov xwm txheej ib puag ncig, thiab lub zog ntawm lub zog magnetic siv. Lawv qhov kev ua tau zoo yog ntsuas raws li lub zog magneto motive (AT - Ampere-Turns), ua rau lawv siv tau ntau yam rau ntau yam kev xav tau ua haujlwm.

Triac lossis Transistor Switches

Cov hloov pauv Triac thiab Transistor nyuaj dua vim lawv cov circuitry ntxiv. Lawv feem ntau yog siv rau kev tswj hwm lub zog thiab kev siv hloov pauv hauv AC (Triac) lossis DC (Transistor) voltage systems. Cov hloov pauv no muaj zog thiab haum rau cov ntawv thov tam sim no lossis hnyav, xws li kev tswj cov motors, relays, lossis inductive loads.

Lawv lub peev xwm nqa tam sim no tuaj yeem txhim kho los ntawm kev sib txuas nrog Hall Effect lossis Reed switches, ua rau lawv zoo tagnrho rau cov chaw ua haujlwm xav tau qhov twg kev ntseeg siab thiab lub zog yog qhov tseem ceeb.

Cov qhov hloov pauv sib nqus siv nyob qhov twg?

Cov hloov pauv sib nqussiv dav thoob plaws ntau yam lag luam thiab daim ntawv thov vim lawv qhov ua tau ntau yam, kev ntseeg siab, thiab muaj peev xwm ua haujlwm yam tsis tas kov lub cev. Hauv qab no yog qee qhov chaw tseem ceeb uas siv cov khoom siv sib nqus:
