1. Feem ntau, ntsuas lub cev muaj nuj nqis yog qhov tsawg heev, thiab feem ntau kuj muaj suab nrov hloov pauv ntawm lub cev hloov pauv ntawm lub sensor. Piv txwv li, lub teeb lub zog ntawm lub teeb liab nyob rau hauv lub magnification ntawm 1 yog 0.1 ~ 1uv, thiab lub suab keeb kwm yav dhau los tseem loj heev uas nws tseem puas tsuaj. Yuav ua li cas rho tawm cov cim tseem ceeb ntau li ntau tau thiab txo cov suab nrov yog qhov teeb meem tseem ceeb ntawm kev tsim qauv.
2. Lub ntsuas hluav taws xob sensor yuav tsum yog qhov yooj yim thiab ua kom zoo nkauj nrog tus 3-theem amplifier Circuit Court thiab kuj ua kom nrov dua lub suab nrov. Yog tias lub suab nrov tsis txawv qhov tseem ceeb ntawm lub teeb liab taw qhia, tsis muaj teeb meem li cas lub lim ntim, ob yog nthuav dav tib lub sijhawm. Lub teeb liab-rau-suab nrov sib piv tsis tau txhim kho.Yog li ntawd, lub ntsuas hluav taws xob yuav tsum tau ua kom zoo nkauj thiab yooj yim. Txhawm rau txuag lub resistor lossis capacitor, nws yuav tsum tau muab tshem tawm. Qhov no yog qhov teeb meem uas muaj ntau cov engineers tsim sensors zoo li pom txog. Nws tau paub tias cov teeb meem kev teeb meem yog tsim cov teeb meem suab nrov, thiab ntau qhov kev hloov kho lub suab nrov yog hloov kho, cov nyom ntau dua, uas dhau los ua lub voj voog coj txawv txawv.
3. Teeb meem siv hluav taws xob. Sensors feem ntau yog nyob rau sab pem hauv ntej ntawm tom ntej lub voj voog thiab tej zaum yuav ua rau cov tshuaj txhuas tsis txaus ntseeg thiab lub zog hluav taws xob tsim nyog thiab tsim kev nyuaj ntxiv. Yuav ua li cas txo lub zog siv thaum nws txaus kuj tseem yog kev sim loj.
4. Xaiv cov khoom siv thiab hluav taws xob Circuit. Cov kev xaiv ntawm Circuities yuav tsum muaj qhov teeb meem ntawm cov khoom siv uas yuav tsum muaj, ntev li cov teeb meem hluav taws xob uas yuav tsum tau ntsib hauv cov qauv tsim qauv ntawm cov txheej txheem sensor. Tsis txhob ua raws li cov khoom siv hluav taws xob tsis muaj zog, tab sis xaiv ib qho OP AMP nrog cov qauv zoo tsis lees paub, thiab siv cov khoom siv hluav taws xob zoo dua qub
