Ibyuma bya salle bishingiye ku ngaruka za Hall.Ingaruka ya Hall nuburyo bwibanze bwo kwiga imiterere yibikoresho bya semiconductor.Coefficient ya Hall yapimwe nigeragezwa ryingaruka za Hall irashobora kugena ibipimo byingenzi nkubwoko bwikwirakwizwa, ubwikorezi bwikwirakwiza hamwe nubwikorezi bwibikoresho bya semiconductor.
Ibyiciro
Ibyuma byububiko bigabanijwemo ibice byumurongo wa Hall hamwe no guhinduranya ibyuma bya Hall.
1. Umurongo wa sensor ya Hall igizwe nibintu bya Hall, umurongo wa amplifier hamwe na emitter ukurikira, kandi usohora ubwinshi bwikigereranyo.
2. Guhindura ubwoko bwa sensor ya Hall igizwe na voltage igenzura, ibintu bya Hall, amplifier itandukanye, imbarutso ya Schmitt hamwe nibisohoka, kandi isohora umubare wa digitale.
Ibintu bikozwe mu bikoresho bya semiconductor bishingiye ku ngaruka za Hall byitwa ibintu bya Hall.Ifite ibyiza byo kwiyumvamo imirima ya magneti, yoroshye muburyo, ntoya mubunini, ubugari mubisubizo byinshyi, binini mubisohoka voltage ihindagurika kandi birebire mubuzima bwa serivisi.Kubwibyo, yakoreshejwe cyane mubice byo gupima, kwikora, mudasobwa nikoranabuhanga ryamakuru.
Main gusaba
Ibyuma byerekana ingoro bikoreshwa cyane nkibikoresho byerekana imyanya, gupima umuvuduko ukabije, guhinduranya imipaka no gupima ibintu.Ibikoresho bimwe bikora bishingiye ku ngaruka za Hall, nkibikoresho bya Hall bigezweho, ibyuma byerekana amababi ya Hall, hamwe ningaruka za magnetiki yumuriro.Ibikurikira, icyerekezo cya sensor, icyerekezo cyihuta nubushyuhe cyangwa sensor ya sensor byasobanuwe cyane.
1. Umuyoboro
Ibyuma byerekana ibyumba byifashishwa mukumva kunyerera, muri ubu bwoko bwa sensor hazabaho icyuho kigenzurwa cyane hagati yikintu cya salle na magneti, kandi umurima wa rukuruzi uterwa imbaraga uzahinduka mugihe rukuruzi igenda isubira inyuma ikajya mu cyuho cyagenwe.Iyo ikintu kiri hafi yamajyaruguru, umurima uzaba mubi, kandi mugihe ikintu kiri hafi yinkingi yepfo, umurima wa magneti uzaba mwiza.Ibyo byuma byitwa kandi ibyuma byegereye kandi bikoreshwa muburyo busobanutse neza.
2. Umuyoboro wihuta
Mu kwihuta, sensor ya salle ya Hall ishyirwa neza ireba magneti azunguruka.Uru rukuruzi ruzunguruka rutanga imbaraga za rukuruzi zisabwa kugirango ukore sensor cyangwa element ya Hall.Itondekanya rya magneti azunguruka irashobora gutandukana, bitewe nuburyo bworoshye bwa porogaramu.Zimwe murizo gahunda ni mugushiraho rukuruzi imwe kuri shaft cyangwa hub cyangwa ukoresheje impeta.Rukuruzi ya Hall isohora impiswi igihe cyose ihuye na magneti.Byongeye kandi, izo pulses zigenzurwa nuwitunganya kugirango amenye kandi yerekane umuvuduko muri RPM.Izi sensor zirashobora kuba digitale cyangwa umurongo ugereranya ibyasohotse.
3. Ubushyuhe cyangwa sensor sensor
Ibyuma bifata ibyuma bya salle birashobora kandi gukoreshwa nkumuvuduko nubushyuhe bwubushyuhe, ibyo byuma bifatanyirizwa hamwe nigitutu cyerekana diafragma hamwe na magneti akwiye, kandi guteranya magnetiki yinzogera ikora ibintu byingaruka za Hall imbere n'inyuma.
Mugihe cyo gupima umuvuduko, inzogera irashobora kwaguka no kugabanuka.Impinduka mu nzogera itera inteko ya magnetiki kwimuka hafi yingaruka za Hall.Kubwibyo, ibisohoka bivamo voltage iringaniza nigitutu gikoreshwa.
Kubijyanye no gupima ubushyuhe, inteko ya bellows ifunzwe na gaze ifite ibimenyetso bizwi byo kwagura ubushyuhe.Iyo icyumba gishyushye, gaze imbere mu nzogera iraguka, bigatuma sensor itanga ingufu zingana nubushyuhe.
