Lub sijhawm zoo siv tus pin thiab pinless noo noo meters
Feem ntau, nws yuav tsim nyog los sim cov ntsiab lus noo noo (% MC) ntawm qee yam tshuaj. Ntxiv mus, thaum kuaj ncaj qha rau cov ntsiab lus noo noo ntawm cov ntaub ntawv, muaj ob rab koob tshuaj tiv thaiv dej hiav txwv noo noo thiab rab koob dawb noo tsawg meter.
Lub koob meter noo meter siv lub ntsiab cai ntawm kev tiv thaiv los ntsuas cov ntsiab lus ya raws hauv cov khoom siv ntau yam. Txij li thaum dej yog tus saib xyuas, cov ntaub ntawv xws li ntoo, paj rwb, gypsum, thiab yooj yim dua qhov tam sim no ntws los ntawm cov khoom, lub weatter nws tiav. Rau lub hom phiaj ntawm precision, nws yog ib qho tseem ceeb kom paub meej tias puas tau ntsuas rab koob yog ntsuas rau cov khoom siv tshwj xeeb tau raug ntsuas kom sib txawv xam cov kev tiv thaiv tam sim no.
Ntawm qhov tod tes, rab koob dawb hydraulic hygrometers Siv xov tooj hluav taws xob zaus rau "luam theej duab" Cov qauv qauv los txiav txim lub xub ntiag dej. Kev hloov kho ntawm electromagnetic vuag yog siv los ntsuas cov dej hauv ib qho qauv. Qhov tseeb ntawm rab koob tshuaj ntsuab dawb noo noo tau cuam tshuam los ntawm cov khoom siv scannity (sg) ntawm cov khoom siv scanned, yog li nws yog qhov tsim nyog kom ntsuas cov cuab yeej rau SG tus nqi ntawm cov khoom. Cov kev nqus tshwj xeeb yog kev ntsuas ntawm cov txheeb ze tus nqi ntawm cov khoom piv rau lwm cov ntaub ntawv (feem ntau yog dej).
Ob rab koob thiab rab koob tsawg Hygrometers muaj lawv cov txiaj ntsig tshwj xeeb thiab qhov tsis zoo, uas tej zaum yuav ua rau lawv muaj cov av noo ntau dua. Thaum twg rab koob hom dej noo me me tau siv thiab thaum twg yuav tsum tau rab koob tshuaj ntsuab dawb noo tsawg meter siv? Cov hauv qab no yog qhov xwm txheej dav nyob qhov twg ib hygrometer yuav zoo dua lwm tus.
Koob dawb noo noo meters yog adept ntawm sai thiab ntsuas tau cov chaw loj loj ntawm cov txheej txheem huab cua. Tsuas yog thawb lub rooj luam ntawv rau hauv pem teb, nyeem nws, tsa nws, thiab rov ua qhov scan hauv lwm txoj haujlwm. Tshawb xyuas pawg thawj coj saib ib zaug los tshuaj xyuas thaj chaw loj, thiab txhua qhov kev tshuaj xyuas tsuas yog siv sijhawm li ob peb feeb xwb. Qhov no tso cai rau cov neeg siv kom sai scan muaj cov chaw loj heev ntawm cov qauv nrog kev txheeb ze yooj yim.
Ntawm qhov tod tes, rab koob hygrometer tsuas yog tshuaj xyuas rau cov dej noo hauv thaj chaw me me ntawm cov koob me me. Ib qho ntxiv, lawv yuav tsum tau delve mus rau hauv cov khoom siv kuaj kom tau nyeem meej. Qhov no feem ntau txhais tau tias ntau zog quab yuam kom nkag siab cov ntaub ntawv nyuaj dua, ua kom muaj kev pheej hmoo ua rau tus lej PIN. Ib qho chaw kuaj me dua thiab kev siv zog ntxiv tuaj yeem pab lub sijhawm thiab tus nqi ua haujlwm rau kev ntsuas cov dej noo dhau ntawm thaj chaw loj.
Koob dawb Hygrometers yuav tsum ua tiav kev sib cuag nrog cov chaw nyeem kom raug. Yog hais tias lub rooj tshawb tawm scanning tsis tuaj yeem tso tau tag nrho cov khoom siv ntsuas, qhov tseeb ntawm lub koob tsawg dua hygrometer yuav cuam tshuam. Ib qho ntxiv, yog tias cov khoom siv scanned tau xoob (xws li rau rwb thaiv tsev lossis quav nyab siab kawg ntawm cov huab cua ntawm cov fibers ntawm cov khoom.
Ntawm qhov tod tes, rab koob hygrometer tuaj yeem siv tau yooj yim los ntsuas cov ntaub ntawv uas xoob tau ntim lossis muaj qhov chaw tsis sib xws. Qhov tseem ceeb yog qhov tam sim no nyob rau hauv cov khoom siv xeem - tsuav muaj muaj ib txoj hauv kev tam sim no kom ntws los ntawm ib tus lej mus rau lwm tus, qhov kev ntsuas tuaj yeem ua tiav. Txawm li cas los xij, txhawm rau sim cov ntsiab lus ya raws hauv cov ntaub ntawv fiberglass rwb thaiv tsev, cov hlau nplaum, thiab lwm yam, cov hluav taws xob tshwj xeeb.
