Electromagnetic detection txoj kev yog ib txoj hauv kev zoo rau kev soj ntsuam kev tawg. Cov ntsiab lus yog raws li nram no:

 

Eddy - Kev Xeem Tam Sim No (ET)

 

Txoj Cai
Thaum ib qho alternating tam sim no dhau los ntawm lub kauj, ib qho chaw sib nqus sib nqus yog tsim nyob ib ncig ntawm nws. Yog tias qhov coil no tau muab tso rau ze rau cov khoom siv hluav taws xob, eddy tam sim no yuav raug ntxias hauv cov khoom. Qhov tshwm sim ntawm qhov tawg yuav hloov cov hluav taws xob conductivity thiab cov duab geometric ntawm cov khoom, yog li cuam tshuam rau kev faib thiab qhov loj ntawm cov eddy tam sim no.
Piv txwv li, thaum muaj qhov tawg ntawm cov khoom nto, txoj kev ntws ntawm cov eddy tam sim no yuav hloov. Qhov kev hloov pauv no tuaj yeem kuaj pom los ntawm qhov ntsuas lub ntsuas hluav taws xob vim tias qhov hloov pauv tam sim no yuav tsim ib qho chaw sib nqus tshiab, thiab qhov chaw sib nqus no yuav cuam tshuam rau qhov tam sim no hauv lub ntsuas hluav taws xob. Cov cuab yeej tshwj xeeb feem ntau yog siv los txheeb xyuas cov kev hloov pauv tam sim no ntawm lub ntsuas hluav taws xob los txiav txim siab qhov muaj nyob ntawm qhov tawg thiab nws cov yam ntxwv cuam tshuam.

 

Daim ntawv thov Scenario
Aerospace Field: Nws yog siv los txheeb xyuas qhov chaw thiab nyob ze - qhov chaw tawg ntawm cov khoom tseem ceeb xws li dav hlau cav hniav thiab tsaws iav. Aircraft cav hniav ua hauj lwm nyob rau hauv high-kub thiab high-kev nyuaj siab ib puag ncig thiab yog nquag ua rau qaug zog tawg. Eddy - kev sim tam sim no tuaj yeem kuaj xyuas cov hniav sai thiab zoo yam tsis muaj kev cuam tshuam cov khoom, ua kom muaj kev nyab xeeb ntawm kev ya davhlau.
Kev lag luam fais fab: Nws yog siv los saib xyuas cov kab nrib pleb hauv cov khoom siv hluav taws xob xws li rotor thiab stator ntawm cov tshuab hluav taws xob. Cov khoom ntawm cov tshuab hluav taws xob no tuaj yeem tsim cov kab nrib pleb vim muaj cov yam ntxwv xws li electromagnetic force thiab mechanical vibration thaum lub sijhawm ua haujlwm ntev. Eddy - kev sim tam sim no tuaj yeem ntes cov kab nrib pleb raws sijhawm thiab tiv thaiv kev ua tsis tiav.
Automobile Manufacturing: Nws yog siv los xyuas qhov zoo ntawm cov khoom xws li crankshaft thiab txuas pas nrig ntawm lub tsheb cav. Cov khoom siv no tuaj yeem tsim cov kab nrib pleb me me thaum lub sijhawm tsim khoom lossis thaum siv, thiab eddy - kev sim tam sim no pab ua kom zoo thiab kev ntseeg siab ntawm cov khoom siv tsheb.

 

Chaw Taws Teeb - Field Eddy - Kev Ntsuas Tam Sim No (RFET)

 

Txoj Cai
Qhov no yog ib qho tshwj xeeb eddy - kev sim tam sim no. Cov hlau nplaum uas tsim los ntawm excitation coil kis tau los ntawm cov yeeb nkab phab ntsa thiab tau txais los ntawm kev tshawb nrhiav coil nyob rau hauv ib cheeb tsam deb ntawm excitation coil (lub cheeb tsam chaw taws teeb). Thaum muaj qhov tawg lossis lwm yam tsis xws luag hauv cov yeeb nkab, nws yuav cuam tshuam rau kev nthuav tawm ntawm cov hlau nplaum, ua rau lub teeb liab tau txais los ntawm kev tshawb nrhiav coil hloov.
Piv nrog cov pa eddy - kev sim tam sim no, tej thaj chaw deb - teb eddy - kev sim tam sim no muaj lub teeb liab nkag mus tob dua thiab muaj kev nkag siab ntau dua rau cov yeeb nkab tsis xws luag. Nws yog tsuas yog raws li cov yam ntxwv propagation ntawm magnetic teb nyob rau hauv cov qauv tshwj xeeb ntawm cov yeeb nkab kom pom qhov tsis xws luag. Lub teeb liab yog reflected thiab refracted ntau zaus ntawm cov phab ntsa sab hauv thiab sab nrauv ntawm cov yeeb nkab, ua kom pom cov kab nrib pleb hauv qhov tob.

Daim ntawv thov Scenario
Kev lag luam Petrochemical: Nws yog siv rau kev saib xyuas lub sijhawm ntev ntawm cov kav dej, tshwj xeeb tshaj yog cov kav dej siv los thauj cov corrosive media. Cov kav dej no muaj kev cuam tshuam rau sab hauv vim yog kev xeb ntev ntev los ntawm kev tshaj tawm. Tej thaj chaw deb - teb eddy - kev sim tam sim no tuaj yeem tshawb xyuas cov kab nrib pleb hauv cov kav dej thiab zam kev nyab xeeb xws li kev tawm mus.
Kev lag luam Nuclear: Nws yog siv los xyuas cov kav dej tseem ceeb xws li cov kav dej txias ntawm cov chaw tsim hluav taws xob nuclear. Vim muaj kev ruaj ntseg siab heev ntawm cov kav dej nuclear fais fab nroj tsuag, tej thaj chaw deb - teb eddy - kev sim tam sim no tuaj yeem ntes cov kab nrib pleb hauv cov kav dej yam tsis muaj kev puas tsuaj rau kev ncaj ncees ntawm cov kav dej thiab ua kom muaj kev nyab xeeb ntawm kev siv hluav taws xob nuclear.
