Lub fluxgate magnetometer yog qhov sib nqus teb sensor rau vector magnetic teb. Nws qhov ntau npaum li cas yog haum rau kev ntsuas lub ntiaj teb teb thiab nws muaj peev xwm daws tau zoo hauv qab ib qho 10,000th ntawm qhov ntawd.
Nws tau ib txwm siv rau navigation thiab compass ua hauj lwm nrog rau hlau nrhiav thiab prospecting. Tsis nyuaj rau kev tsim nws yog feem ntau tsis nco qab nyob rau hauv niaj hnub ntiaj teb no ntawm silicon thiab MEMS li.
Fluxgate magnetometer designs poob rau hauv dav dav ob hom, cov neeg ua haujlwm rod cores thiab cov neeg siv lub nplhaib cores. Whilst muaj ntau lwm yam kev tsim qauv feem ntau raws li tus pas nrig cores tsis tau mus txog lub xeev ntawm txoj kev loj hlob thiab kev ua tau zoo los ntawm ob hom. Vim li no, nplooj ntawv no tsuas yog siv rau cov pas nrig ntxaib thiab lub nplhaib core fluxgate variants.
Tag nrho cov fluxgates siv ib tug heev permeable core uas ua hauj lwm rau mloog zoo rau cov magnetic teb los ntsuas. Cov tub ntxhais yog magnetically saturated hloov nyob rau hauv tawm tsam cov lus qhia raws li ib tug haum axis, feem ntau yog siv los ntawm ib tug excitation coil tsav los ntawm ib tug sine los yog square waveform.
Ua ntej saturation lub ambient teb yog channeled los ntawm cov tub ntxhais ua ib tug high flux vim nws siab permeability. Thaum lub sij hawm saturation lub core permeability ntog mus rau ntawm lub tshuab nqus tsev vacuum ua rau lub flux mus vau. Thaum lub sij hawm ib nrab ntawm lub voj voog tom ntej ntawm qhov excitation waveform cov tub ntxhais rov qab los ntawm saturation thiab cov flux vim lub ambient teb yog ib zaug dua nyob rau theem siab kom txog rau thaum cov tub ntxhais saturates nyob rau hauv lub opposite direction; lub voj voog ces rov ua dua. Txawm hais tias lub magnetisation reversals vim yog excitation, lub flux los ntawm ambient teb ua hauj lwm nyob rau hauv tib txoj kev mus thoob plaws. Ib qho kev nkag siab coil tso nyob ib ncig ntawm cov tub ntxhais yuav khaws cov flux hloov pauv qhov kos npe ntawm qhov induced voltage qhia tias flux vau lossis rov qab los. Lub npe fluxgate kom meej meej muab los ntawm qhov kev txiav txim ntawm cov tub ntxhais nkag mus rau hauv thiab tawm ntawm lub siab coil.
Cov txheej txheem no tau pom nyob rau hauv daim duab ntawm sab laug raws li qhov zoo tshaj plaws waveforms, thiab nws tuaj yeem pom tseeb tias qhov kev nkag siab voltage yog ob zaug ntawm qhov kev tawm dag zog.
Demodulation schemes feem ntau siv 2nd harmonic nrhiav tau vim li no. Hauv kev xyaum rau ib tus pas nrig zoo li tus tub ntxhais qhov kev nkag siab coil yuav tuaj tos lub excitation tsav nrog rau cov teeb liab voltage uas vim nws qib siab tuaj yeem ua pov thawj teeb meem tshem tawm hluav taws xob.
Ib qho kev daws teeb meem rau qhov no yog siv ob qho tib si cores nrog rau theem excitation thim ntawm ib qho mus rau lwm qhov. Lub siab coil khaws lub teeb liab tab sis qhov induced excitation voltage yog muab tso tseg los ntawm theem reversal, ua waveforms zoo ib yam li cov qhia ntawm no.
Raws li tau piav qhia, qhov voltage ntawm flux hloov peaks yog los ntawm Faraday txoj cai proportional rau lub magnetic teb; ib qho yooj yim sensor yuav siv tau nyob rau hauv txoj kev no. Txawm li cas los xij, tus qauv tsim zoo tshaj plaws yuav siv lub kauj (qhov kev nkag siab coil feem ntau ua ob npaug rau txoj haujlwm no) los tawm tswv yim sib nqus teb rau qhov tsis txaus ntseeg xws li ob daim teb tso tseg ib leeg. Hauv hom kev ua haujlwm no, qhov twg lub fluxgate yog siv los ua lub ntsuas tsis tau, qhov tam sim no nyob rau hauv cov lus taw qhia kauj yog proportional rau qhov kev xav. Cov txheej txheem txhim kho linearity ntawm kev ntsuas, tso cai rau ntau dua dynamic ntau kom tiav thiab yog siv los ntawm feem ntau ntawm niaj hnub
khoom siv.
