Inkcazelo yeemveliso
I-CIPPUS CAP-DP series differential pressure transmitter ivelele njengesisombululo esisebenza kakuhle esilungiselelwe iimfuno zanamhlanje zokulinganisa imboni. Yenziwe ngeetships ze-silicon pressure-sensitive chips kunye noyilo oludibeneyo lwesekethe, inika impendulo ekhawulezayo, uvakalelo oluphezulu, kunye nokusebenza okuthembekileyo ixesha elide ngaphandle kokulinganiswa rhoqo. Ulwakhiwo lwayo oluncinci noluqinileyo luvumela ukumelana nokungcangcazela, ukushaqeka, kunye nokubola kwemidiya okuqatha, okwandisa kakhulu ubomi benkonzo.
I-transmitter ixhasa ukufakwa okuguquguqukayo kunye nokulungiswa kweengxaki okulula kwindawo, inciphisa ngokufanelekileyo iindleko zokugcinwa kunye nokuphucula uzinzo lwenkqubo. Ngobuchule obuphezulu bokulwa nokuphazamiseka kunye nobubanzi bobushushu bokusebenza, isebenza ngokuzinzileyo kwiimeko zokusebenza ezinzima ezifana nonyango lwamanzi, ipetroliyam, ubunjineli beekhemikhali, kunye nezityalo zamandla. Idibanisa ukuchaneka okuphezulu, ukuguquguquka okunamandla, kunye nokusebenza kakuhle kweendleko, lukhetho olukhethwayo lokujonga uxinzelelo oluchanekileyo kunye neenkqubo zolawulo lwemizi-mveliso ezikrelekrele.
I-Diffused Silicon Differential Pressure Transmitter yethu yenzelwe njengesisombululo esiqinileyo, esigxile ngokuchanekileyo esilungiselelwe iimfuno ezigqithisileyo zoshishino lwe-petrochemical, esijongana neendawo eziphambili zentlungu ezifana ne-corrosive media, ukuguquguquka kobushushu, kunye neengozi eziqhumayo. Yakhiwe nge-silicon sensing core ecocekileyo kakhulu eyenziwe ngcono ngetekhnoloji ye-MEMS, inika ukuchaneka okugqwesileyo kokulinganisa (± 0.05% FS) kunye ne-ultra-low long-term drift (≤0.1% FS/ngonyaka), iqinisekisa idatha ethembekileyo kwiinkqubo ezibalulekileyo ezifana nokucocwa kweoyile eluhlaza, ukucutshungulwa kwegesi yendalo, kunye nokuhlanganiswa kweekhemikhali.
Into eyenza ukuba ibaluleke kakhulu kwizicelo zepetrochemical kukuqina kwayo okuphezulu kokusingqongileyo. Izixhobo ze-contact medium zisebenzisa ii-diaphragms ze-Hastelloy C-276 okanye i-316L zentsimbi engagqwaliyo, ezidityaniswe nezitywino ze-PTFE, zenza umqobo oqinileyo ngokuchasene nezinto ezirhabaxa ezifana ne-H₂S, i-chlorine, kunye ne-acidic/alkaline fluids. Iqinisekiswe ngokhuseleko lwangaphakathi lwe-ATEX Ex ia IIC T4 kunye ne-Ex d flameproof ratings, isebenza ngokukhuselekileyo kwiindawo ezinobungozi ze-Zone 0/1, ngelixa umgangatho wokhuseleko lwe-IP67/IP68 uthintela ukungena kothuli kunye nokufuma kwiindawo ezinobungozi zezityalo. Uluhlu lwayo olubanzi lobushushu bokusebenza (-40℃ ukuya kwi-125℃) kunye nenkqubo yokuhlawula ubushushu edityanisiweyo ye-laser isusa iimpazamo ezibangelwa kubushushu obukhulu okanye ukubanda kwiinqaba zokunyibilikisa, iikettle ze-reaction, kunye neenethiwekhi zepayipi.
Yenzelwe ukusebenza kakuhle kwemizi-mveliso, le transmitter inesakhiwo esomeleleyo esidityaniswe ngokupheleleyo esimelana noxinzelelo oluphezulu (ukuya kuthi ga kwi-42MPa uxinzelelo olungaguqukiyo) kunye nokungcangcazela koomatshini, ithintela iingozi zokuvuza kwiimeko zomthwalo ophezulu njengeeplatifomu zokubhola kude nolwandle. Ixhasa ukuphuma kwesignali eguquguqukayo (i-4–20mA analog + HART protocol) yokudibanisa ngaphandle komthungo neenkqubo zeDCS/PLC, ivumela uqwalaselo lweeparameter ezikude kunye nokugcinwa kwangaphambili—kunciphisa ixesha lokungasebenzi kwe-calibration kwindawo nge-60%. Uyilo lwe-anti-overload (ukuya kuthi ga kwi-5x full scale) kunye ne-electromagnetic interference (EMI) shielding zikhusela kwi-pressure surges kunye nengxolo yombane evela kwizixhobo zoshishino, ukuqinisekisa ukuphuma okuzinzileyo nakwiimeko zenkqubo ezinzima.
Ukususela ekutsalweni kweoyile ephezulu ukuya ekucutshungulweni kweekhemikhali ezisezantsi, le transmitter igqwesile ekulinganiseni ukuhamba kwamanzi, ukujonga amanqanaba, kunye nokulawula uxinzelelo lweegesi, ulwelo, kunye nomphunga. Inciphisa ukuvalwa okungacwangciswanga, yehlisa iindleko zokugcinwa, kwaye iphucula ukhuseleko lokusebenza—iyenza ibe lolona khetho lukhethwayo kumashishini e-petrochemical afuna ukuchaneka, ukuqina, kunye nokuthobela imigangatho yoshishino. Uyilo lwayo oluncinci kunye neendlela zokufakela ezinokuguquguquka (i-flange, intambo, i-bracket) zilungelelanisa ngakumbi nofakelo olunemida yendawo, zibonelela ngokusebenza okuzinzileyo kwiindawo zokucocisa, izityalo zeekhemikhali, kunye namaqonga aselunxwemeni.
