Magneto Electric Ceev Sensor

Electromagnetic velocity sensors yog hom sensor uas siv txoj cai ntawm electromagnetic induction (Faraday's Law) kom ncaj qha hloov kev vibration tshaj tawm mus rau hauv lub teeb liab hluav taws xob. Nws tsis tas yuav muaj hluav taws xob sab nraud thiab yog tus kheej - tsim (lub zog- tsim) sensor.

 

Nws lub hauv paus ntsiab lus tseem ceeb yog: Qhov loj ntawm electromotive quab yuam (EMF) tshwm sim nyob rau hauv lub kaw Circuit Court yog proportional rau tus nqi ntawm cov sib nqus flux los ntawm lub Circuit Court.

Ib tug raug electromagnetic velocity sensor feem ntau muaj cov nram qab no Cheebtsam:

• Magnet:Muab qhov chaw sib nqus tas li.
• Coil:Ib tug conductor uas txav mus rau hauv lub magnetic teb.
• Caij nplooj ntoos hlav-Mass System:Qhov tseem ceeb mechanical txav ib feem.
• Pov thawj Mass:Feem ntau txuas nrog lub kauj (tsav- hom coil) lossis rau cov hlau nplaum (tsav- hom hlau nplaum).
• Caij nplooj ntoos hlav:Txhawb nqa cov ntaub ntawv pov thawj thiab txiav txim siab lub cev muaj zog.

Lub tsev nyob sensor yog tsau rau cov khoom vibrating yog ntsuas thiab vibrates nrog nws.

Vim yog inertia, cov ntaub ntawv pov thawj sab hauv feem ntau nyob twj ywm los yog nyob rau hauv nws thawj lub xeev ntawm kev txav.

Yog li ntawd, kev sib txheeb ntawm cov lus tsa suab tshwm sim ntawm lub tsev thiab cov pov thawj loj.

Qhov kev txheeb ze no ua rau lub kauj txuas txuas ntxiv txiav cov kab sib nqus ntawm lub zog (lossis hloov pauv, cov kab hlau nplaum raug txiav los ntawm kauj), yog li tsim hluav taws xob hluav taws xob (EMF) hla qhov kawg ntawm lub kauj.

Raws li txoj cai lij choj ntawm electromagnetic induction, qhov loj ntawm qhov induced EMF yog proportional rau tus nqi ntawm lub coil txiav cov sib nqus kab ntawm lub zog (piv txwv li, qhov txheeb ze tshaj tawm).

Cov ntsiab lus yooj yim:Nws ncaj qha converts "vibration tshaj tawm" rau hauv "voltage."
