Plaub -Kev sojntsuam Electrode Txheej Resistivity Tester

Specification

Txheej txheem cej luam

1.1 Basic Functions thiab Basis Standards:

Basic muaj nuj nqi:Ib qho kev sojntsuam rau kev ntsuas qhov kev tiv thaiv / perpendicular tshwj xeeb tsis kam ntawm cov coatings ntawm cov ntawv ci, nruab nrog cylindrical tiaj- lub taub hau sojntsuam, siv ua ke nrog plaub- sojntsuam ntsuas thiab ntsuas lub rooj ntev zaum los ntsuas qhov resistivity / perpendicular tshwj xeeb tsis kam ntawm coatings ntawm hlau ntawv.

Basic composition:Cov kev sojntsuam tiav muaj xws li kev sojntsuam, kev sojntsuam tuav, lub cev lub cev cylindrical, kuaj lub rooj ntev zaum txuas cov txiv ntseej, ntsuas kev sib txuas cables thiab lwm yam khoom siv.

Kev sib tw thiab kev sib tw:Qhov kev sojntsuam no tau sib xws nrog tag nrho plaub -cov cuab yeej sojntsuam thiab plaub- sojntsuam kuaj lub rooj zaum ntawm peb lub tuam txhab, thiab kuj tseem sib xws nrog plaub- sojntsuam cov cuab yeej ntawm feem ntau lwm cov tuam txhab.

1.2 Ua kom tiav Cov Txheej Txheem ntawm Cov Khoom Siv:Muaj plaub lub- sojntsuam lub ntsiab chav tsev, lub siab tshuav nyiaj li cas, txuas cables thiab lwm qhov chaw.

1.3 Advantage nta:

A. Kev soj ntsuam ntawm Irrationality ntawm Kev Ntsuas Resistivity ntawm Coatings ntawm Ntawv Nyiaj nrog Cov Plaub Plaub-Txoj Kev Tshawb Fawb
Vim hais tias cov khoom coated ntawm cov ntawv ci yog txhuas lossis tooj liab ntawv nrog qis resistivity thiab zoo hluav taws xob conductivity tshaj li txheej nws tus kheej, thiab txheej ntawm cov ntawv ci yog nyias nyias, cov hluav taws xob conductivity raws lub dav hlau kev taw qhia yuav tsum tsis zoo, piv txwv li, tus nqi impedance kuj loj.

Thaum kuaj cov roj teeb electrode nrog cov qauv plaub- kev sojntsuam, qhov kev faib tawm tam sim no yog raws li pom hauv daim duab 2. Txij li thaum lub substrate yuav luag luv luv -circuits tam sim no thiab shunts feem ntau ntawm qhov ntsuas tam sim no, tam sim no shunted ntawm txheej ntawm cov ntawv ci yog me me, thiab qhov ntsuas hluav taws xob kuj tseem tsawg heev. Yog li ntawd, qhov tshwm sim nominal tom qab kev sim yog deb me dua li tus nqi tiag tiag. Cov qauv sib xyaw zoo li no tsis haum rau cov qauv plaub - kev sojntsuam sojntsuam ntxiv lawm. Qhov yuav tsum tau ua ua ntej ntawm plaub- kev sojntsuam sojntsuam: cov khoom nyob rau hauv kev sim yog ib qho kev sib xyaw, isotropic thiab homogeneous.

B. Schematic daim duab ntawm kev txhim kho kev sim txheej txheem rau txheej txheej ntawm cov ntawv ci

Txhawm rau kuaj cov hluav taws xob conductivity ntawm lub roj teeb electrode cov khoom siv coated ntawm cov ntawv ci, cov electrode ua haujlwm yog simulated. Hauv kev taw qhia lub voj tam sim no, plaub- lub ntsiab lus ntsuas qhov ntsuas hluav taws xob yog siv los ntsuas qhov ntsuas lub voj tam sim no. Lub hauv paus ntsiab lus muaj nyob rau hauv daim duab 3: lub voj tam sim no yog tam sim no electrode zoo → txheej → tooj liab (aluminium) ntawv ci → txheej → tam sim no electrode tsis zoo. Kev sim tau ua pov thawj tias qhov kev tiv thaiv ntawm tooj liab (aluminium) ntawv ci yog nyob rau hauv qhov kev txiav txim ntawm ob peb milliohms, accounting rau tsawg dua 1% ntawm tag nrho cov kev tiv thaiv, thiab tuaj yeem tsis quav ntsej. Qhov kev xeem RT=V/I yog suav tias yog qhov sib npaug ntawm qhov tsis kam ntawm ob txheej txheej. Raws li qhov cuam tshuam derivation, qhov resistivity thiab perpendicular tshwj xeeb tsis kam ntawm txheej tuaj yeem xam.

1.4 Test Bench Nta thiab cov lus qhia siv:

Qauv loj: yam tsawg kawg nkaus tus qauv loj 4mm × 10mm; loj dav hlau qhov ntev thiab thickness yog unlimited.

Kev ntsuas qhov sib nrug: linear ob -pin kev npaj, qhov sib nrug 8.0mm.

Kev sojntsuam: phosphor tooj liab alloy + npib tsib xee-plated / kub-plated, Φ4.0mm.

Siab: 200 ~ 1000g adjustable, ntsuas siab approx . 500g. Kho los ntawm lub rooj zaum xeem.

Rau cov nplooj ntawv roj teeb ua ntej dov, uas yog siab- cov qauv ntsuas ntsuas, lub digital- tso saib lub rooj zaum siab nrog kev ntsuas siab tuaj yeem xaiv tau.

1.5 Scope ntawm daim ntawv thov:Cov cuab yeej tsim nyog rau cov khoom siv hluav taws xob hluav taws xob thiab cov chaw ua haujlwm los ntsuas cov hluav taws xob conductivity ntawm cov roj teeb electrode siv plaub- txoj kev davhlau ya nyob twg.
