Hauv cov nroj tsuag tshuaj, ntsuas cov kua dej kom raug thiab ntseeg tau yog qhov tseem ceeb rau kev tswj xyuas kev nyab xeeb thiab ua haujlwm tau zoo.Ib qho ntawm feem ntau siv tej thaj chaw deb telemetry teeb liab kua theem sensors yog lub siab zoo li qub kua theem transmitter.Txoj kev no suav cov kua theem los ntawm kev ntsuas lub siab zoo li qub ntawm cov kua kem hauv lub nkoj.Hauv tsab xov xwm no, peb yuav tham txog cov ntsiab lus tseem ceeb xaiv thiab kev siv ntawm XDB502 kua theem sensor hauv cov khoom siv tshuaj.
Nta thiab Qhov Zoo
XDB502 kua theem sensor muaj ntau yam nta thiab qhov zoo uas ua rau nws haum rau ntau yam kev siv hauv cov nroj tsuag tshuaj.Cov no suav nrog:
Kev siv tau rau hauv qhov kub thiab txias, siab-siab, siab viscosity, thiab corrosive ib puag ncig, ua rau nws haum rau ntau yam kev siv.
Kev ntsuas loj uas txawv raws li thaj chaw, thiab tsis muaj qhov muag tsis pom kev.
Muaj kev ntseeg siab, ruaj khov, lub neej ntev, thiab cov nqi tu qis.
Kev ntsuas siab, nrog qhov tseeb txog + 0.075% tag nrho teev (fs) rau cov khoom siv hluav taws xob zoo li qub thiab + 0.25% fs rau cov khoom siv hluav taws xob hauv tsev zoo li qub siab ua kua theem transmitters.
Kev txawj ntse tus kheej kev kuaj mob thiab chaw taws teeb chaw ua haujlwm.
Muaj ntau hom teeb liab tso zis kev xaiv, suav nrog cov txheej txheem sib txawv rau cov qauv 4mA-20mA tam sim no cov cim qhia, mem tes signals, thiab fieldbus kev sib txuas lus.
Xaiv cov ntsiab lus
Thaum xaiv ib lub siab zoo li qub kua theem transmitter, cov ntsiab lus hauv qab no yuav tsum xav txog:
Yog tias qhov sib npaug sib npaug (qhov sib txawv siab) tsawg dua 5KPa thiab qhov ceev ntawm qhov ntsuas nruab nrab hloov pauv ntau dua 5% ntawm tus nqi tsim, yuav tsum tsis txhob siv lub siab sib txawv ntawm cov kua theem transmitter.
Cov kua flammability, explosiveness, toxicity, corrosiveness, viscosity, muaj cov khoom raug tshem tawm, evaporation nyiam, thiab nyiam condense ntawm ambient kub yuav tsum tau txiav txim siab thaum xaiv lub transmitter.
Lub transmitter tuaj yeem tsim nrog ib leeg lossis ob lub flanges.Rau ob flange transmitters, lub capillary ntev yuav tsum sib npaug.
Rau cov kua uas ua rau crystallization, sedimentation, siab viscosity, coking, los yog polymerization, ib tug diaphragm hom txawv siab siab transmitter nrog ib tug insertion sealing txoj kev yuav tsum tau xaiv.
Nyob rau hauv ib puag ncig uas cov roj theem tuaj yeem condense thiab cov kua theem yuav evaporate, thiab lub thawv nyob rau hauv high-kub thiab high-pressure tej yam kev mob, ib tug condenser, cais, thiab tshuav lub thawv yuav tsum tau ntsia thaum siv ib tug tsis tu ncua sib txawv kua theem transmitter rau Kev ntsuas dej ntsuas.
Qhov tseeb sib txawv siab ua kua theem transmitter feem ntau xav tau ntau yam hloov dua siab tshiab.Yog li ntawd, lub transmitter yuav tsum muaj ntau yam offset muaj nuj nqi, thiab tus nqi offset yuav tsum yog tsawg kawg yog 100% ntawm lub sab sauv txwv ntawm ntau yam.Thaum xaiv ib lub transmitter, qhov offset yuav tsum tau txiav txim siab, tshwj xeeb tshaj yog thaum ntsuas high-density media.Yog li ntawd, lub transmitter qhov ntau yuav tsum tau xaiv raws li qhov teeb meem offset.
Cov xwm txheej siv
XDB502 kua theem sensor muaj ntau yam kev siv uas yuav tsum tau xav txog:
Cov txheej txheem kub: Hom transmitter no ua haujlwm los ntawm kev xa cov siab los ntawm cov kua filling ntim ntim rau hauv lub cuab yeej.Cov kua ua kua ntau suav nrog 200 silicone, 704 silicone, chlorinated hydrocarbons, sib tov ntawm glycerol thiab dej, thiab lwm yam.Txhua cov kua filling muaj qhov ntsuas kub kom tsim nyog, thiab hom filling yuav tsum raug xaiv raws li cov khoom siv tshuaj ntawm qhov ntsuas nruab nrab thiab cov txheej txheem kub.Yog li ntawd, thaum cov txheej txheem kub siab tshaj 200 ℃, kev siv lub diaphragm-sealed transmitter yuav tsum tau ua tib zoo xav txog.Yog tias tsim nyog, lub kaw lus txuas txuas ntxiv lossis cov khoom siv thermal optimization yuav tsum raug xaiv, thiab cov chaw tsim khoom xa tawm yuav tsum paub meej cov ntsiab lus.
Ambient kub: Cov kua filling yuav tsum tau ntim ntawm qhov tsim nyog ambient kub.Lub capillary yuav tsum tau khaws cia raws li cov kua filling qhov kub.Raws li epoxyethane nyob rau hauv cov khoom siv hluav taws xob EOEG yog qhov yooj yim rau polymerization, lub diaphragm-sealed sib txawv siab ua kua theem transmitter yuav tsum tau siv los ntsuas epoxyethane nruab nrab qib.Raws li cov kev daws teeb meem carbonate yog nquag mus rau crystallization, lub diaphragm-sealed sib txawv siab ua kua theem transmitter yuav tsum tau siv, nrog rau cov ntsiab lus ntxig flush nrog cov cuab yeej sab hauv phab ntsa.Qhov kev ntxig ntxig sab nraud thiab qhov ntev yog txiav txim siab raws li cov khoom siv tshwj xeeb.Rau cov khoom siv nrog lub nruas ua haujlwm kub ntawm 250 ℃ lossis siab dua, yuav tsum tau siv lub raj xa dej tsis tu ncua.
Xaus
Hauv kev xaus, XDB502 kua theem sensor yog ib qho kev txhim khu kev qha thiab muaj tseeb rau kev ntsuas cov qib kua hauv cov nroj tsuag tshuaj.Nws muaj ntau yam zoo, nrog rau ntau yam, siab precision, muaj ntau yam teeb liab tso zis kev xaiv, thiab txawj ntse tus kheej kuaj.Thaum xaiv lub transmitter, cov kua lub zog, xws li flammability, explosiveness, toxicity, corrosiveness, thiab viscosity, yuav tsum tau txiav txim siab.Tsis tas li ntawd, kev siv tej yam kev mob xws li cov txheej txheem kub thiab ambient kub yuav tsum tau coj mus rau hauv tus account kom paub meej qhov tseeb thiab txhim khu kev qha ntsuas.
