Yuav Ua Li Cas Txuas Ntxiv Lub Neej Ntawm Cov Kub Kub Kub Kub Kub Sensors

Los ntawm kev xaiv cov ntaub ntawv tsim nyog, ua cov txheej txheem kev saib xyuas kom zoo ib yam, thiab ua kom qhov chaw ua haujlwm zoo dua, lub neej ntawm cov kub khiav kub sensors tuaj yeem nce siab heev. Kev siv cov ntaub ntawv uas tuaj yeem tiv taus qhov kub thiab txias, teeb tsa lub voj voog ua haujlwm tsis tu ncua, thiab tsim kom muaj ib qho kev ceeb toom ntawm kev ua txhaum thaum ntxov yog peb lub tswv yim tseem ceeb raws li kev tawm tswv yim los ntawm kev siv tiag - ntiaj teb no. Hauv qhov xwm txheej zoo tshaj plaws, qhov no tuaj yeem ua rau lub sensor nyob ntev txog 8 xyoo ntev dua li qhov nws xav tau yam tsis muaj.




I. Optimizing Material Selection: Ua tej yam ntev dua



Cov khoom siv rau lub sensor ncaj qha cuam tshuam qhov ruaj khov nws nyob rau hauv huab cua ib puag ncig xws li kub siab, corrosion, thiab kev co.



Xaiv qhov ntsuas qhov ntsuas qhov ntsuas kub: Platinum-rhodium alloy, alumina-coated thermocouples, lossis ceramic-encapsulated platinum resistance thermometers (PT100) yog txhua qhov kev xaiv zoo. Cov ntaub ntawv no tuaj yeem khaws lawv cov duab hauv qhov chaw uas qhov kub siab tshaj 300℃ntev. Qhov no txwv tsis pub thermoelectric tej zaum drift los ntawm tshwm sim thaum lub lattice yog distorted.



Siv Cov Khoom Siv Los Tiv Thaiv -Kev laus Encapsulation: Armor cov qauv ua los ntawm polytetrafluoroethylene (PTFE), Hastelloy, los yog stainless hlau yog zoo heev ntawm kev tiv thaiv tshuaj corrosion thiab mechanical hnav. Lawv yog cov tshwj xeeb tshaj yog zoo rau kev ua cov ntaub ntawv uas muaj corrosive gases, xws li PVC thiab PC txhaj molding.



Xaiv cov txheej insulating zoo li mica thiab ceramics uas muaj cov rwb thaiv tsev siab thiab zoo thermal conductivity. Qhov no yuav pab kom ntsuas qhov ntsuas kub kom raug los ntawm kev tiv thaiv kom tsis txhob muaj dej los yog siab dua thermal resistance.







II. Kev Tu thiab tu tsis tu ncua: Ib qho tseem ceeb rau Kev Tiv Thaiv Kev Tiv Thaiv: Kev teeb tsa lub sijhawm saib xyuas tsis tu ncua tuaj yeem txo cov naj npawb ntawm kev ua tsis tiav tam sim ntawd.



Ntxuav lub sojntsuam txhua peb mus rau rau lub hlis:



Rau cov plua plav ib txwm, siv daim ntaub qhuav, mos lossis txhuam los so nws.



Txhawm rau ntxuav cov roj, siv anhydrous ethanol.



Txhawm rau tshem tawm cov nplai lossis cov pob zeb, muab tso rau hauv ib qho kev daws ntawm 5% mus rau 10% hydrochloric acid rau 5 mus rau 10 feeb, ces yaug nrog dej huv. Tsis txhob siv tej yam nyuaj los khawb qhov ntsuas qhov ntsuas kub.



Tshawb xyuas qhov kev sojntsuam lub cev txhua rau lub hlis rau cov kab nrib pleb, deformation, thiab qhov chaw corrosion. Tsis tas li ntawd, xyuas kom meej tias lub installation muaj kev ruaj ntseg kom kev co tsis hloov qhov tob ntawm qhov ntxig.



Calibration rau qhov tseeb Txhua 6 mus rau 12 Lub Hlis: Rau kev siv, calibration yuav tsum tau ua ib xyoos ib zaug. Rau siab - xav tau kev txiav txim siab, suav nrog cov khoom siv kho mob, calibration yuav tsum tau ua txhua peb lub hlis. Yog tias qhov tsis raug loj dhau lawm, siv cov qauv ntsuas ntsuas qhov sib piv los yog tus kws tshaj lij calibrator los kho nws lossis hloov nws.



Teeb ib phau ntawv ceev xwm txheej. Khaws taug qab lub sij hawm nws yuav siv rau nruab, cov ntaub ntawv calibration, thiab cov ntsiab lus ntawm tej teeb meem. Platinum tiv thaiv tus pas ntsuas kub muaj sia nyob txog 2-3 xyoos, tab sis cov thermocouples tsuas kav li 6-12 lub hlis ntawm qhov kub thiab txias. Nws yog qhov zoo tshaj los hloov cov khoom ua ntej nws tas sij hawm.







III. Fault Warning and Smart Monitoring: Tau Txais Cov Teeb Meem Ua Ntej.



Siv cov txheej txheem thev naus laus zis los nrhiav kev phom sij ua ntej kom tsis txhob muaj qhov ua tsis tiav.



Siv cov algorithm los them rau qhov kub thiab txias. Siv ntau-point calibration thiab AI dynamic them qauv los txhim kho kev ntsuas qhov yuam kev uas tshwm sim hauv lub sijhawm vim qhov kub thiab txias. Qhov no yuav ua rau lub kaw lus ruaj khov nyob rau lub sijhawm.



Ntxiv cov sensors uas tuaj yeem ua tus kheej - kuaj mob. Xaiv cov sensors digital nrog TEDS (Electronic Data Sheet for Sensors) uas tuaj yeem txheeb xyuas lawv tus kheej, khaws lawv cov xwm txheej, thiab ntsuas qhov deb. Qhov no ua rau nws yooj yim dua los tsim kom muaj kev tswj xyuas qhov kub thiab txias ^[A9]^.



Teem lub tswb ceeb toom yuav txawv. Lub kaw lus cia li nug txog kev tshuaj xyuas lossis hloov pauv thaum ntsuas qhov ntsuas kub hloov ntau dua ± 2 degree, lub sijhawm teb nce mus txog 50%, lossis cov rwb thaiv tsev tiv thaiv poob qis dua 20MΩ.



IV. Environmental thiab Installation Optimization: Txo kev puas tsuaj los ntawm sab nraud



Tiv thaiv thermal shock thiab mechanical stress



Thaum txhim kho, xyuas kom tseeb tias qhov tob tob yog 8 mus rau 10 npaug ntawm txoj kab uas hla ntawm cov raj tiv thaiv. Siv lub txee-tam sim no lossis 45℃angled insertion method kom tsis txhob yaj yaig thiab thermal qaug zog ^[A7].



Zoo dua ntawm kev tshem tawm cov cua sov thiab khaws cov dej noo tawm



Rau cov cheeb tsam uas muaj qhov kub thiab txias, siv cov dab dej kub los yog cov ntaub thaiv cua sov. Rau qhov chaw sab nraum zoov lossis ntub dej, siv sealer thiab desiccant kom tsis txhob muaj kev sib tsoo luv luv.



Txuas ntawm nws tus kheej, tiv thaiv kev cuam tshuam



Txhawm rau txiav kev cuam tshuam ntawm electromagnetic cuam tshuam, cov kab teeb liab siv ob npaug -cov kab thaiv thaiv kab thiab raug cais tawm tsis yog nyob rau hauv tandem nrog cua sov cables ^[A7]^.
