Lub sensor ceev yog ib qho cuab yeej siv los ntsuas qhov ceev ntawm lub tsheb, feem ntau lub log ceev thiab lub log kev taw qhia. Nws feem ntau yog siv los ua ib feem ntawm lub tshuab ntsuas hluav taws xob, uas yog cov cuab yeej ntsuas qhov ceev ntawm lub tsheb tsav. Cov sensors ceev tau muaj rau ntau tshaj 150 xyoo thiab tau hloov zuj zus mus rau hauv cov cuab yeej siv niaj hnub no.
Hom kev nrawm tshaj plaws yog Hall-Effect sensor, uas siv cov hlau nplaum thiab hluav taws xob los ntsuas lub log ceev. Hom sensor no ua haujlwm los ntawm kev hla lub log-mounted magnetic rotor hla lub Hall-effect circuit nyob ruaj khov. Raws li lub log thiab hlau nplaum tig, Hall-effect circuit generates hluav taws xob teeb liab, uas yog siv los xam lub log ceev.
Lub Hall nyhuv ceev sensor muaj ib lub log hlau uas muaj ib tug hlau nplaum txuas nrog nws ncej thiab ib tug nyob ruaj ruaj phaj uas muaj ib tug me me hlau phaj thiab ib tug integrated circuit. Raws li lub log tig, nws hla lub phaj ruaj khov. Cov hlau nplaum uas tsim los ntawm cov hlau nplaum yog tom qab ntawd kuaj pom los ntawm cov hlau phaj thiab cov kev sib xyaw ua ke, uas ua rau cov hluav taws xob tso tawm raws li lub log ceev. Cov zis no ces siv los tswj lub cav RPM thiab cov teeb liab cuam tshuam.
Cov hlau nplaum tas mus li siv nyob rau hauv cov nyhuv nrawm nrawm yog feem ntau hu ua lub log-mounted hlau nplaum rotor. Cov hlau nplaum rotor no feem ntau txuas nrog lub log ncej thiab muaj ib txheej ntawm cov hlau nplaum tso rau ib qho kev ncua deb. Cov hlau nplaum tsim ib qho chaw sib nqus nyob rau hauv daim ntawv ntawm ib tug series ntawm alternating sab qaum teb thiab sab qab teb ncej; Thaum lub log tig, cov ncej sab qaum teb thiab sab qab teb dhau los ntawm cov phaj nrog cov nyhuv ntawm qhov tsis tu ncua, ua kom muaj hluav taws xob tsis tu ncua.
Nws yog ib qho tseem ceeb rau cov hlau nplaum nyob rau hauv ib tug Hall-effect speed sensor yuav tsum nyob rau hauv qhov kev sib raug zoo thiab muaj tus naj npawb ntawm cov hlau nplaum thiab nyob deb ntawm lawv. Yog tias qhov kev sib raug zoo raug kaw, nws tuaj yeem ua rau qhov tsis raug ntawm qhov tso zis ntawm qhov ntsuas qhov nrawm. Lub rotor thiab Hall-effect phaj kuj yuav tsum tau ua kom zoo nyob rau hauv kev sib raug zoo rau ib leeg; Yog tias muaj kev cuam tshuam ntau dhau ntawm lub rotor thiab lub phaj, cov zis yuav tsis raug.
Hauv cov ntsiab lus, cov sensors ceev yog cov cuab yeej siv los ntsuas qhov ceev thiab kev taw qhia ntawm lub tsheb tsav. Lawv feem ntau yog nyob rau hauv daim ntawv ntawm Hall-effect sensor thiab siv lub log-mounted hlau nplaum thiab hluav taws xob Circuit Court los ntsuas lub log ceev. Lub sensor ceev muaj ib lub log hlau nrog lub hlau nplaum rotor txuas nrog nws cov ncej, thiab ib lub phaj nyob ruaj ruaj uas muaj cov phaj hlau me me thiab ib qho kev sib xyaw ua ke. Raws li lub log tig, cov hlau nplaum rotor hla dhau ntawm cov phaj hlau thiab cov kev sib txuas ua ke, tsim cov khoom siv hluav taws xob uas siv los ntsuas lub log ceev. Cov zis yog ces siv los tswj ntau lub cav teeb liab thiab tsis.
