Lub hauv paus ntsiab lus ntawm fluxgate yog lub hauv paus ntsiab lus ntawm electromagnetic sensor raws li lub hauv paus ntsiab lus ntawm magnetic induction. Nws kuaj pom txoj haujlwm, ceev thiab kev taw qhia ntawm lub hom phiaj los ntawm kev txheeb xyuas qhov kev hloov pauv uas tshwm sim thaum dhau los ntawm qhov chaw sib nqus.
Lub fluxgate sensor muaj tsib yam tseem ceeb: cov hlau nplaum, nws cov txheej txheem, fluxgate, sensor, thiab processor. Cov hlau nplaum yog lub luag haujlwm tsim kom muaj qhov chaw sib nqus ruaj khov. Nws sab nrauv tiv thaiv thiab ruaj ntseg cov hlau nplaum thiab sensor. Lub fluxgate yog siv los txuas cov hlau nplaum sib nqus ntawm lub sensor thiab lub hom phiaj khoom. Lub sensor yog ib feem uas tau kuaj pom qhov hloov pauv tam sim no hauv fluxgate. Lub processor yog lub luag haujlwm rau kev txais, ua, thiab hloov cov zis sensor rau hauv lub teeb liab siv tau.
Lub hauv paus ntsiab lus ua haujlwm ntawm fluxgate sensor tuaj yeem piav qhia los ntawm Faraday txoj cai ntawm electromagnetic induction. Raws li txoj cai no, thaum tus neeg xyuas pib (qhov no yog lub rooj vag flux) dhau los ntawm qhov chaw sib nqus, qhov cuam tshuam tam sim no yog tsim nyob rau hauv tus neeg xyuas pib. Qhov loj thiab kev taw qhia ntawm qhov induced tam sim no nyob ntawm seb qhov kev sib txheeb ntawm qhov sib nqus induced conductor thiab magnetic teb.
Thaum ib lub hom phiaj ze rau lub fluxgate, nws cuam tshuam nrog lub magnetic teb. Qhov kev cuam tshuam no yuav ua rau qhov sib txuas ntawm cov flux hauv lub rooj vag flux hloov pauv, ua rau muaj kev hloov pauv ntawm qhov cuam tshuam tam sim no. Lub sensor yuav ntes qhov kev hloov pauv tam sim no thiab hloov mus rau hauv qhov hluav taws xob lossis cov teeb liab digital.
Fluxgate sensors muaj ntau yam zoo. Ua ntej, lawv tsis hnov tsw rau kev hloov pauv ntawm ib puag ncig sab nraud xws li cov khoom siv xim, kub thiab teeb pom kev zoo. Qhov no ua rau lawv haum rau ntau qhov kev thov ib puag ncig. Qhov thib ob, lub fluxgate sensor muaj cov lus teb ceev ceev thiab tuaj yeem ntes cov kev hloov pauv hauv lub hom phiaj ntawm lub sijhawm. Tsis tas li ntawd, lawv muaj kev daws teeb meem siab thiab rhiab heev thiab tuaj yeem pom qhov hloov pauv me me. Thaum kawg, lub fluxgate sensor kuj muaj kev tiv thaiv siab - muaj peev xwm cuam tshuam rau sab nraud cuam tshuam xws li electromagnetic cuam tshuam thiab kev co, yog li txhim kho qhov ruaj khov thiab raug ntawm lub sensor.
Txawm li cas los xij, fluxgate sensors kuj muaj qee qhov tsis zoo. Ua ntej, lawv muaj qee qhov kev xav tau ntawm cov duab thiab qhov loj ntawm lub hom phiaj. Tshwj xeeb tshaj yog, lub hom phiaj khoom yuav tsum muaj peev xwm ua kom muaj kev cuam tshuam ntawm magnetic teb loj txaus rau lub sensor kom ntes nws. Qhov thib ob, vim tias fluxgate sensors yuav tsum tsim kom muaj qhov chaw sib nqus tas li, lawv xav tau qee qhov kev siv hluav taws xob. Qhov no yuav dhau los ua teeb meem hauv qee qhov qis- lub zog thiab ntev- lub neej daim ntawv thov scenarios. Tsis tas li ntawd, kev ua hauj lwm deb ntawm fluxgate sensors yog luv luv, feem ntau ob peb millimeters mus rau ob peb centimeters. Qhov no txwv lawv txoj kev siv hauv qee qhov kev thov.
Nyob rau hauv luv luv, lub fluxgate sensor yog ib tug electromagnetic sensor raws li lub hauv paus ntsiab lus ntawm magnetic induction, siv los xyuas qhov chaw, ceev thiab kev taw qhia ntawm lub hom phiaj khoom. Lawv muaj qhov zoo ntawm qhov tsis hnov tsw rau sab nraud ib puag ncig, teb nrawm, kev daws teeb meem siab thiab rhiab heev, thiab muaj zog tiv thaiv - muaj peev xwm cuam tshuam. Txawm li cas los xij, lawv muaj qee qhov kev xav tau ntawm cov duab thiab qhov loj ntawm lub hom phiaj, xav tau qee qhov kev siv hluav taws xob, thiab kev ua haujlwm nyob deb kuj luv.
