Basic Electrometer

ES-9078A

Cov khoom siv pom zoo:

Basic Electrometer yog voltmeter siv rau kev ntsuas ncaj qha ntawm voltage thiab indirect ntsuas ntawm tam sim no thiab nqi. Vim nws siab impedance ntawm 10¹⁴ ohms, tshwj xeeb tshaj yog haum rau kev ntsuas tus nqi hauv kev sim electrostatic. Nws muaj qhov rhiab heev ze li ib txhiab npaug ntawm tus qauv goldleaf electroscope, qhov chaw-zero
'meter' zaub uas ncaj qha qhia tus nqi polarity, thiab tus lej tso saib. Basic Electrometer ntsuas tus nqi qis li 10-11 coulombs.
Cov cuab yeej tseem tuaj yeem tso tawm cov teeb liab mus rau PASCO analog interface. Cov yam ntxwv no ua rau electrostatics ua qauv qhia thiab cov chaw sim ntau ntau thiab ua tau yooj yim dua.
The Basic Electrometer is powered by four AA-alkaline batteries (included). These batteries can be easily replaced by opening the back casing of the electrometer.

Kev ua haujlwm

Cov ntu hauv qab no piav qhia yuav ua li cas kom teeb tsa thiab siv Basic Electrometer.

Teeb tsa

1. Txuas lub BNC plug ntawm lub teeb liab input cable (kuaj txhuas) rau BNC jack nyob rau sab ntawm Basic Electrometer. Txhawm rau lock rau hauv qhov chaw, kab nce cov pegs ntawm BNCT Jack nrog rau lub ntsaws, thawb lub ntsaws tag nrho kom txog thaum
2. Siv cov txiv tsawb ntsaws qaum txuas rau hauv av chaw nres nkoj ntawm lub tshuab hluav taws xob mus rau hauv av hauv av.
3. Nias lub ON/OFF khawm tig lub electrometer. Cov lej tso saib, ntsuas ntsuas, thiab ib qho ntawm voltage ntau qhov ntsuas yuav pom.
4. Nias lub ZERO khawm kom xoom Lub LED ntawm lub ntsuas ntsuas yuav ua raws li "0" cim, thiab cov lej zaub yuav qhia 0.0.
5. Nias lub Voltage range selector khawm xaiv qhov xav tau voltage ntau yam (3, 10, 30, lossis 100).

Qhov kev teeb tsa ntau yog hais txog qhov voltage cov tswv yim yuav tsum tsim kom muaj ib lub meter deflection tag nrho. Rau example, qhov chaw ntawm 30 txhais tau hais tias lub 'meter' yuav tsum tau tag nrho deflected los ntawm voltagua 30v.

Cov ntsiab lus tseem ceeb rau kev ua haujlwm dav dav

• TSIS TXHOB siv Basic Electrometer los ntsuas qhov muaj peev xwm ntau dua 100 V.
• Tsis txhob txuas lub tshuab hluav taws xob mus rau lub tshuab hluav taws xob electrostatics, xws li Van de Graaff generator lossis Wimhurst tshuab.
• Tsis txhob kov cov tswv yim coj mus txog thaum koj tau cog koj tus kheej mus rau hauv lub ntiaj teb Ib tug neeg taug kev hla ib daim ntaub ntawm ib hnub txias, qhuav tuaj yeem yooj yim kis tau ntau txhiab volts.
• Nco ntsoov nias lub khawm ZERO ntawm kev ntsuas kom tso tawm cov nqi ntau dhau los ntawm electrometer. Shorting qhov kev xeem coj ua ke yog qhov tsis txaus, vim tias tseem yuav muaj cov nqi yuam kev hauv lub voj voog.

• Kom tau txais txiaj ntsig zoo tshaj plaws, TSIS TXHOB txuas lub tshuab hluav taws xob mus rau hauv av, xws li cov kav dej lossis cov xaim hauv av los ntawm lub qhov hluav taws xob 120 VAC, thaum sim. Tsuas yog lub ntiaj teb hauv av tuaj yeem muab qhov tso dej txaus rau kev tsim cov nqi ntau dhau thaum lub sijhawm
• Tus neeg sim yuav tsum tau nyob hauv av thaum ua qhov no, kov ib txhais tes rau hauv av hauv av ua ntej lossis thaum ntsuas.

Ntsuas voltage

Basic Electrometer tuaj yeem kho tau raws li qhov tsis muaj qhov kawg impedance voltmeter. Txhawm rau siv lub ntsuas hluav taws xob ua lub ntsuas hluav taws xob, txuas lub teeb liab input cable coj mus rau lub roj teeb, teeb lub voltage range, thiab nyeem voltage ntawm lub ' meter ' lossis tus lej tso saib.

Ntsuas tus nqi ntawm induction

Nyob rau hauv feem ntau cov xwm txheej, txoj kev zoo tshaj plaws los ntsuas tus nqi yog los ntawm induction. Siv lub dav hlau pov thawj thiab Faraday ice pail, xws li cov uas suav nrog Electrostatics System (ES-9080B) thiab qhia hauv qab no.

Lub dav hlau pov thawj tsuas yog ib qho me me conductive disk mounted ntawm ib qho insulating kov. Rau sample qhov kev faib tawm ntawm cov khoom raug them, tsuas yog kov cov khoom nrog lub dav hlau pov thawj, tom qab ntawd tso cov ntaub ntawv pov thawj hauv lub tog raj kheej sab hauv ntawm lub thawv dej khov, tsis muaj kov lub tog raj kheej. Tus nqi sib npaug ntawm qhov sib npaug thiab kos npe yog raug ntxias rau saum npoo ntawm lub thawv dej khov thiab tuaj yeem nyeem tau los ntawm Basic Electrometer.

Los ntawm ib txwm siv cov ntaub ntawv pov thawj lub dav hlau thiab cov dej khov, lub peev xwm yuav zoo ib yam rau txhua qhov kev ntsuas, thiab tus nqi ntawm cov ntaub ntawv pov thawj lub dav hlau yuav ib txwm sib npaug rau lub vol.tage nyeem ntawm electrometer.

Ntsuas tus nqi ntawm kev sib cuag

Tus nqi kuj tuaj yeem ntsuas los ntawm kev sib cuag. Yog tias koj kov lub cylinder sab hauv ntawm lub thawv dej khov nrog cov khoom siv, xws li lub foob pob hluav taws, qhov kev nyeem ntawv electrometer feem ntau yuav nyob twj ywm tsis hloov. Qhov no yog vim hais tias tag nrho cov capacitance tsuas yog negligibly cuam tshuam los ntawm cov ntaub ntawv pov thawj dav hlau. Txawm li cas los xij, qhov no yuav tsis yog ib txwm muaj.
Txhua qhov kev ntsuas tus nqi nrog lub electrometer yog indirect, raws li kev paub tias tus nqi ntawm tus nqi ntawm cov khoom yog proportional rau
Kev nyeem ntawv yuav ib txwm ntsuas hauv volts, tsis yog coulombs. Txawm li cas los xij, qhov polarity ntawm voltage ncaj qha qhia txog hom kev them nqi yog sampcoj. Yog tias xav tau kev ntsuas tus nqi ntau dua li cov ntaub ntawv zoo, tus nqi tuaj yeem ntsuas tau siv qhov sib npaug Q = CV, qhov twg V
yog voltage hla ib tug paub capacitor ntawm capacitance C.
Basic Electrometer tuaj yeem xav tias yog ib qho impedance voltmeter infinite nyob rau hauv parallel nrog lub capacitor CE, raws li qhia hauv daim duab 2.
CE sawv cev rau sab hauv capacitance ntawm lub electrometer, ntxiv rau
capacitance ntawm cov txhuas thiab cov dej khov ntim yog tias cov no tau siv. Thaum ib qho khoom them raug muab tso rau thoob plaws lub ntsuas hluav taws xob (lossis mus rau hauv lub thawv dej khov), ib qho voltage V yog tso tawm rau ntawm lub 'meter'. Yog tus nqi CE paub, tus nqi ntawm tus nqi tuaj yeem suav nrog kev sib npaug Q = CEV.

Lub capacitance ntawm lub electrometer ib leeg yog hais txog 27 picofarads (pF). Txawm li cas los xij, yog tias sampcoj cov khoom ntxiv qhov tseem ceeb capacitance, qhov xwm txheej hloov mus rau qhov pom hauv daim duab 3, nrog Cext yog lub capacitance ntawm cov khoom. Kom raug xam tus nqi ntawm
them nyob rau hauv cov ntaub ntawv no, tag nrho cov capacitance CE + Cext yuav tsum tau txiav txim. Qhov no yuav tsum muaj tus nqi raug rau CE, tshwj tsis yog tias koj paub tseeb tias cov khoom koj ntsuas muaj qhov muaj peev xwm txaus txaus kom tsis quav ntsej CE (Cext >> CE). Nco ntsoov tias qhov no yog tsis yog rooj plaub thaum siv Basic Variable Capacitor (ES-9079). Cov lus hauv qab no yuav piav qhia txog yuav ua li cas ntsuas qhov kev sim ntsuas tus nqi ntawm lub tshuab hluav taws xob, ib qho cables txuas nrog nws, thiab lub thawv dej khov.

Ntsuas lub capacitance ntawm lub electrometer thiab connectors

Thaum ib tug paub capacitor C yog them los ntawm ib tug paub voltage V, tus nqi nyob rau hauv lub capacitor yog muab los ntawm Q = CV. Yog hais tias lub capacitor nrog tus nqi paub txuas nrog hla cov kev coj ntawm lub tshuab hluav taws xob, nws txuas nrog rau qhov sib npaug nrog cov khoom siv sab hauv. CE ntawm electrometer, ice pail, thiab cables. Yog li ntawd, tag nrho capacitance ua C + CE. Lub capacitor paub yuav tso tawm thoob plaws hauv Basic Electrometer, thiab voltage VE tuaj yeem nyeem tau. Txij li thaum tag nrho cov nqi ntawm lub system yog tseem Q, peb paub tias:
Siv cov txheej txheem no los ntsuas tus nqi meej ntawm lub peev xwm muab los ntawm electrometer thiab cov cuab yeej txuas nrog:

1. Tau txais lub tshuab xa hluav taws xob tsawg (polypropylene lossis cua dielectric) ntawm tus nqi paub C cav 30pf.
2. Them lub capacitor nrog ib tug paub voltage V. Qhov no voltage yuav tsum tsis txhob siab tshaj 100 V, vim qhov no yog qhov txwv ntawm qhov
