Yuav ua li cas tswj qhov tseeb hauv qhov ntsuas kub ntsuas?

Los ntawm kev lag luam thiab kev ua zaub mov mus rau kev kho mob thiab kev tshawb fawb tshawb fawb, cov cuab yeej ntsuas kub ua rau cov pob txha ntawm ntau qhov sib txawv. Txij li cov tshuab no cuam tshuam ncaj qha rau kev nyab xeeb, kev ua tau zoo, thiab cov khoom zoo, lawv qhov tseeb yog qhov tseem ceeb heev. Ob peb lub ntsiab lus tseem ceeb yuav tsum raug coj mus rau hauv tus account yog tias ib tus xav ua kom qhov tseeb no.
Txhua qhov system ntsuas kub pib nrog cov sensors. Piv txwv li, Thermocouples yog siv ntau heev vim lawv qhov yooj yim thiab dav qhov kub thiab txias. Lawv ua hauj lwm ntawm Seebeck nyhuv, nyob rau hauv uas teb rau ib tug kub sib txawv voltage yog tsim nyob rau hauv lub hlws ris ntawm ob yam hlau. Tseem, kev xaiv tsim nyog ntawm hom thermocouple yog qhov tseem ceeb heev los lav lawv qhov tseeb. Ntau hom thermocouples yog tsim los rau qee qhov kub thiab txias ib puag ncig. Hom R thermocouples yog siv rau siab - precision thiab siab - kub nyeem ntawv; Hom K thermocouples yog qhov tsim nyog rau kev siv lub hom phiaj dav dav hauv qhov kub thiab txias. Kev siv yam tsis raug yuav ua rau muaj kev ua yuam kev loj. Nws zoo li ntsuas qhov ntev ntawm qhov chaw ncaws pob nrog ib daim kab xev ntsuas meant rau qhov deb me me.
Tseem muaj lwm yam tseem ceeb hauv kev khaws cia qhov tseeb yog calibration. Cov xwm txheej zoo li ambient tej yam kev mob, mechanical stress, thiab tivthaiv kev laus tej zaum yuav ua rau kub sensors mus los ntawm lawv thawj calibration lub sij hawm. Kho cov kev sib txawv no yuav tsum tau calibration tsis tu ncua siv cov qauv siv traceable. Hauv chav kuaj, qhov twg yuav tsum tau tswj qhov kub thiab txias rau kev kawm, calibration yuav xav tau ntau zaus. Piv txwv li, cov cuab yeej ntsuas kub ntsuas ntsuas ntsuas tsis tuaj yeem sib tham hauv lub chaw tshawb fawb tshuaj vim tias qhov ntsuas kub ntsuas ntsuas thaum muaj tshuaj lom neeg txiav txim siab tsim cov tshuaj tshiab. Calibrating ib tug kub sensor yog zoo li kho lub suab seev; yam tsis muaj kev kho kom haum, cov ntaub ntawv tshwm sim-uas tawm ntawm --- tune instrument-yuav skewed.
Qhov tseeb kuj nyob ntawm qhov ntsuas kub ntawm qhov ntsuas kub. Kev ntsuas qhov kub thiab txias ntawm lub hom phiaj lossis ib puag ncig yog nyob ntawm cov sensors raug muab tso rau. Yog tias qhov ntsuas kub hauv qhov cub siv rau ci yog qhov chaw nyob ze ntawm qhov cua sov, qhov kev nyeem ntawv yuav siab dua qhov kub hauv chav ci. Hloov pauv, yog tias nws nyob deb dhau lawm, nws yuav tsis pom qhov ntsuas kub hloov pauv uas xav tau rau kev ci. Tsis tas li ntawd, kev teeb tsa ntawm lub sensor yuav tsum txo qis kev cuam tshuam ntawm kev hloov hluav taws xob. Rau cov yeeb nkab xa cov kua dej kub, piv txwv li, lub sensor yuav tsum tau muab tso rau txhawm rau tsim kom muaj kev sib cuag zoo nrog cov kua dej tsis muaj kev cuam tshuam los ntawm qhov kub ntawm cov yeeb nkab phab ntsa.
Qhov tseeb yuav raug cuam tshuam los ntawm ib puag ncig cov cuab yeej ntsuas qhov kub thiab txias, tiv thaiv cov sensors thiab cov xov hlau cuam tshuam yog qhov tseem ceeb hauv kev xav tau kev lag luam nrog cov qib siab ntawm electromagnetic cuam tshuam, zoo li cov hlau zeb lossis lub zog cog. Kev nyeem ntawv kub tsis raug yog los ntawm electromagnetic teb induction ntawm hluav taws xob nrov hauv cov cuab yeej ntsuas. Hauv cov chaw uas muaj cov khoom siv corrosive, zoo li lub chaw ua tshuaj, cov sensors kuj xav tau kev tiv thaiv los ntawm cov txheej txheem tsim nyog los yog sheaths. Lub sensor raug rau corrosive yam tsis muaj shielding yuav maj mam deteriorate, yog li cuam tshuam nws qhov tseeb. Txawm tias qhov ntsuas kub tsim tau zoo tuaj yeem ua tsis tau nyob rau hauv qhov chaw maritime, qhov twg dej hiav txwv tuaj yeem ua rau muaj kev xeb, yog tias tsis muaj chaw nyob zoo.
Kev tswj xyuas qhov tseeb ntawm qhov ntsuas qhov ntsuas kub kuj tseem nyob ntawm cov khoom ntawm cov ntaub ntawv sau thiab ua tiav. Ib tug xav tau cov ntaub ntawv zoo khaws cov khoom siv nrog cov suab nrov tsawg thiab kev daws teeb meem txaus. Kev sau cov ntaub ntawv nrog high-precision analogue - rau - digital converters yog ib qho tseem ceeb hauv kev siv xws li semiconductor fabrication thaum lub sij hawm doping txheej txheem thaum feeb kub variations yuav tsum tau hnov. Tsis tas li ntawd, kev lim dej kom tsim nyog thiab cov teeb liab txias tuaj yeem pab tshem tawm cov teeb liab kub tsis zoo cuam tshuam lossis suab nrov. Cov txheej txheem cua txias thiab lim dej tshem tawm cov khoom paug tawm ntawm cov ntaub ntawv kub, yog li tsuas yog tso cov ntaub ntawv ntshiab thiab raug, ntau npaum li kev ntxuav cov dej ntshiab.
Kev tswj xyuas qhov tseeb hauv qhov ntsuas kub ntsuas yog li ntawd hu rau kev ceev faj rau kev xaiv sensor, nquag calibration, tsim nyog installation, kev tiv thaiv ib puag ncig, thiab cov ntaub ntawv zoo khaws thiab ua. Los ntawm tackling cov ntsiab lus no, cov lag luam tuaj yeem lav tias lawv cov ntsuas ntsuas kub muab cov ntaub ntawv raug thiab zoo ib yam, yog li tso cai rau lawv txiav txim siab zoo thiab khaws cov qauv zoo tshaj plaws thiab kev nyab xeeb hauv lawv txoj haujlwm.
