Cov Lus Nug thiab Lus Teb Txog Ntoo Moisture Meters
Nqe Lus Nug 1: Vim li cas kuv thiaj li yuav tsum siv lub ntsuas dej noo?
Qhov no yog tej zaum cov lus nug feem ntau ntawm cov neeg siv hygrometer thawj zaug. Txawm hais tias cov lus teb tshwj xeeb rau lo lus nug no yuav txawv ntawm kev lag luam, cov lus teb feem ntau cuam tshuam txog qhov zoo.
Siv lub ntsuas dej noo, koj tuaj yeem txheeb xyuas qhov teeb meem uas cov qauv ntawm cov ntoo tuaj yeem ntsib, xws li tawg, shrinkage, splitting, pwm loj hlob, thiab lwm yam. Thaum cov dej noo ntawm cov ntoo siab dhau (los yog tsawg dhau, qee zaum), qhov zoo ntawm cov khoom kawg tuaj yeem raug kev txom nyem.
Siv lub ntsuas dej noo yuav pab koj xyuas kom meej tias cov dej noo ntawm cov khoom ntoo uas koj siv yog nyob rau hauv qhov tseeb feem pua MC ntau yam kom tsis txhob hu rov qab rau yav tom ntej.
Nqe Lus Nug 2: Dab tsi yog qhov sib txawv ntawm cov ntoo noo noo ntsuas?
Thaum muaj ntau tus qauv hygrometer suav tsis txheeb ntawm kev ua lag luam, thiab cov tshiab tshwm sim txhua lub sijhawm, lawv poob rau hauv ob pawg raws li lawv txoj haujlwm:
Suab.
Noob nplej.
Tus pin hygrometer siv ob (lossis ntau dua) electrodes nkag mus rau cov khoom siv ntoo los nyeem cov feem pua MC ntawm cov khoom siv uas siv lub hauv paus ntsiab lus ntawm kev tiv thaiv. Hauv ob-pin meter, ib tus pin qhov chaw tam sim no thiab lwm qhov tau txais tam sim no, thiab lub ntsuas ntsuas txhais qhov tsis kam ntawm qhov tam sim no tawm tsam tam sim no. Txij li cov ntoo yog ib qho insulator thiab dej yog tus neeg xyuas pib, qhov tsis kam rau hluav taws xob tam sim no, qhov siab dua cov ntoo ntawm cov dej noo.
Pinless meters, ntawm qhov tod tes, siv xov tooj cua electromagnetic nthwv dej los luam theej duab cov qauv ntoo hauv qab lub ntsuas ntsuas phaj. Cov ntsuas no qee zaum hu ua non-intrusive ya raws ntsuas vim tias lawv tsis tas yuav nkag mus rau hauv cov ntoo kom tau txais kev nyeem ntawv.
Nqe Lus Nug 3: Hom kev ntsuas dej noo twg zoo dua?
Tom qab nug txog cov khoom sib txawv ntawm cov ntsuas dej noo, cov neeg feem coob kuj xav paub seb qhov ntsuas dej noo yog hom twg zoo tshaj. Cov lus teb feem ntau nyob ntawm hom kev ua haujlwm uas koj tab tom ua, qhov loj ntawm cov khoom ntoo uas koj ua haujlwm nrog, txawm tias koj tawm hauv cov khoom siv, thiab koj tus kheej nyiam.
Lub meter tsis muaj koob yog nrawm thiab yuav tsis ua rau lub ntsej muag ntawm cov khoom raug tshuaj xyuas. Pins, ntawm qhov tod tes, tuaj yeem muab cov ntaub ntawv tshwj xeeb rau koj txog kev faib dej noo hauv cov ntoo.
Ntau tus kws tshaj lij siv ob hom kev ntsuas hauv lawv txoj haujlwm, hloov ntawm ob qho raws li qhov tsim nyog.
