Izinzwa zeHolo zisekelwe kwisiphumo seHolo.Umphumo weHolo yindlela esisiseko yokufunda iimpawu zezixhobo ze-semiconductor.I-Coefficient yeHolo elinganiswe ngovavanyo lwesiphumo seHolo inokumisela iiparitha ezibalulekileyo ezifana nohlobo lwe-conductivity, i-concentration concentration kunye ne-carrier mobility of semiconductor materials.
Ukuhlelwa
Izinzwa zeHolo zahlulwe zibe ziingqondi zeHolo ezihambelanayo kunye nokutshintsha izinzwa zeHolo.
1. I-Linear Hall sensor iqulethe i-Holo element, i-amplifier yomgca kunye nomlandeli we-emitter, kunye neziphumo zobuninzi be-analog.
2. I-switch-type ye-Hall sensor iqulunqwe ngumlawuli we-voltage, iHolo yeHolo, i-amplifier yokwahlukana, i-Schmitt trigger kunye nesigaba sokuphuma, kunye neziphumo zobuninzi bedijithali.
Izinto ezenziwe ngezinto ze-semiconductor ezisekelwe kwimpembelelo yeHolo zibizwa ngokuba yiHolo yeHolo.Ineengenelo zokuba nobuntununtunu kumandla kazibuthe, ilula kulwakhiwo, incinci ngokobukhulu, ibanzi ngokuphendula rhoqo, inkulu kuguquko lwamandla ombane kunye nexesha elide kubomi benkonzo.Ke ngoko, isetyenziswe ngokubanzi kwimimandla yokulinganisa, i-automation, ikhompyuter kunye netekhnoloji yolwazi.
Makukho sicelo
Izinzwa zempembelelo yeholo zisetyenziswa ngokubanzi njengeenzwa zesikhundla, ukulinganisa isantya sokujikeleza, ukutshintshwa komda kunye nokulinganisa ukuhamba.Ezinye izixhobo zisebenza ngokusekwe kwisiphumo seHolo, njengeeSensom zeHolo zangoku, ii-switch switches zamagqabi, kunye ne-Hall effect izinzwa zamandla ombane.Emva koko, i-sensor yesikhundla, inzwa yesantya sokujikeleza kunye neqondo lokushisa okanye inzwa yoxinzelelo ichazwa kakhulu.
1. Isivamvo sokuma
Abenzi boluvo besiphumo seholo basetyenziselwa ukuva intshukumo yokutyibilika, kolu hlobo lwesivamvo kuya kubakho umsantsa olawulwa ngokuqinileyo phakathi kwento yeholo kunye nomazibuthe, kwaye indawo enemagnethi eya kutshintsha iya kutshintsha njengoko umazibuthe ebuyela emva naphambili kumsantsa omiselweyo.Xa i-element ikufuphi ne-pali engasentla, intsimi iya kuba ne-negative, kwaye xa i-elementi ikufuphi ne-pali esezantsi, i-magnetic field iya kuba yinto enhle.Ezi zivamvo zikwabizwa ngokuba zii-proximity sensors kwaye zisetyenziselwa indawo echanekileyo.
2. Isivamvo sesantya
Kwimvakalelo yesantya, inzwa yesiphumo seHolo ibekwe ngokuzinzileyo ijonge umazibuthe ojikelezayo.Lo mazibuthe ujikelezayo uvelisa intsimi kazibuthe efunekayo ukuze kusebenze isivamvo okanye into yeHolo.Ukucwangciswa kweemagnethi ezijikelezayo kunokwahluka, kuxhomekeke kuncedo lwesicelo.Amanye ala malungiselelo kukufaka umazibuthe omnye kwishafti okanye kwi-hub okanye ngokusebenzisa imagnethi.Inzwa yeHolo ikhupha i-pulse ephumayo ngalo lonke ixesha ijongene nemagnethi.Ukongeza, ezi pulses zilawulwa yiprosesa ukumisela kunye nokubonisa isantya kwi-RPM.Ezi zinzwa zinokuba yi-digital okanye i-linear analog sensors output.
3. Ubushushu okanye inzwa yoxinzelelo
Abenzi boluvo besiphumo seholo banokusetyenziswa njengoxinzelelo kunye nezivamvo zobushushu, ezi zivamvo zidityaniswe noxinzelelo lwe-diaphragm ejikisayo kunye nemagnethi efanelekileyo, kwaye indibano yemagnethi yemvulo ivuselela isiphumo seHolo emva naphambili.
Kwimeko yokulinganisa uxinzelelo, i-bellows ixhomekeke ekwandiseni kunye nokunciphisa.Utshintsho kwimivumbo lwenza ukuba indibano yemagnethi isondele kwindawo yesiphumo seHolo.Ngoko ke, i-voltage ephumayo ephumayo ilingana noxinzelelo olusetyenzisiweyo.
Kwimeko yokulinganisa ubushushu, indibano ye-bellows itywinwe ngerhasi eneempawu ezaziwayo zokwandiswa kwe-thermal.Xa igumbi lifudunyezwa, igesi engaphakathi kwi-bellows iyanda, nto leyo eyenza ukuba i-sensor ivelise i-voltage ehambelana nobushushu.
