I-CAP-DP Diffused Silicon Diffected Pressure Transmitter RS485 420mA Yamanzi Amakhemikhali Kawoyela

Isidluliseli sokucindezela esihlukile sochungechunge lwe-CIPPUS CAP-DP sivelele njengesixazululo esisebenza kahle kakhulu esilungiselelwe izidingo zesimanje zokulinganisa izimboni. Sakhiwe ngama-chips e-silicon asezingeni eliphezulu azwela ukucindezeleka kanye nomklamo wesekethe ohlanganisiwe, sinikeza impendulo esheshayo, ukuzwela okuphezulu, kanye nokusebenza okuthembekile kwesikhathi eside ngaphandle kokulinganiswa okuvamile. Isakhiwo saso esincane nesiqinile senza ukumelana nokudlidliza, ukushaqeka, kanye nokugqwala kwemidiya okunzima, okwandisa kakhulu impilo yesevisi.

I-transmitter isekela ukufakwa okuguquguqukayo kanye nokulungisa amaphutha okulula endaweni, inciphisa ngempumelelo izindleko zokulungisa futhi ithuthukise ukuzinza kohlelo. Njengoba inekhono eliphezulu lokulwa nokuphazamiseka kanye nobubanzi bokushisa bokusebenza, isebenza kahle ezimweni zokusebenza eziyinkimbinkimbi njengokwelashwa kwamanzi, uphethiloli, ubunjiniyela bamakhemikhali, kanye nezitshalo zikagesi. Ihlanganisa ukunemba okuphezulu, ukuzivumelanisa nezimo okunamandla, kanye nokusebenza kahle kwezindleko, kuyindlela ekhethwayo yokuqapha okunembile kokucindezela okuhlukile kanye nezinhlelo zokulawula zezimboni ezihlakaniphile.

I-Diffused Silicon Differential Pressure Transmitter yethu yakhiwe njengesixazululo esiqinile, esigxile ekuqondeni esilungiselelwe izidingo ezinkulu zemboni yamakhemikhali kaphethiloli, sibhekana nezindawo ezibuhlungu ezibalulekile njengemidiya egqwalisayo, ukushintshashintsha kwezinga lokushisa, kanye nezingozi eziqhumayo. Yakhiwe nge-silicon sensing core ehlanzekile kakhulu eyenziwe ngcono ngobuchwepheshe be-MEMS, inikeza ukunemba kokulinganisa okumangalisayo (± 0.05% FS) kanye nokukhukhuleka kwesikhathi eside okuphansi kakhulu (≤0.1% FS/ngonyaka), iqinisekisa idatha ethembekile yezinqubo ezibalulekile njengokuhluzwa kukawoyela ongahluziwe, ukucubungula igesi yemvelo, kanye nokuhlanganiswa kwamakhemikhali.​

Okwenza kube yinto ebalulekile ekusetshenzisweni kwe-petrochemical ukuqina kwayo okuphezulu kwemvelo. Izingxenye ze-contact medium zisebenzisa ama-diaphragm ensimbi engagqwali e-Hastelloy C-276 noma angu-316L, ahlanganiswe nezimpawu ze-PTFE, akha isithiyo esiqinile ngokumelene nezinto ezibolayo njenge-H₂S, i-chlorine, kanye noketshezi olune-acidic/alkaline. Iqinisekiswe ukuphepha kwangaphakathi kwe-ATEX Ex ia IIC T4 kanye nezilinganiso ze-Ex d ezingashisi ilangabi, isebenza ngokuphephile ezindaweni eziyingozi ze-Zone 0/1, kuyilapho izinga lokuvikela le-IP67/IP68 livimbela ukungena kothuli kanye nomswakama ezindaweni zezitshalo ezinzima. Ububanzi bayo bokushisa obusebenzayo obubanzi (-40℃ kuya ku-125℃) kanye nesistimu yokunciphisa izinga lokushisa ehlanganisiwe elinganiswe nge-laser isusa amaphutha abangelwa ukushisa okukhulu noma ukubanda emibhoshongweni yokucwilisa, ama-kettle okusabela, kanye namanethiwekhi epayipi.​

Yakhelwe ukusebenza kahle kwezimboni, le transmitter inesakhiwo esiqinile esihlanganisiwe esimelana nokucindezela okuphezulu (kufika ku-42MPa ingcindezi engaguquki) kanye nokudlidliza komshini, igwema izingozi zokuvuza ezimweni zomthwalo ophezulu njengezinkundla zokubhoboza zasogwini. Isekela ukuphuma kwesignali okuguquguqukayo (iphrothokholi ye-analog + HART engu-4–20mA) yokuhlanganiswa okungenamthungo nezinhlelo ze-DCS/PLC, ivumela ukucushwa kwamapharamitha akude kanye nokugcinwa kokubikezela—kunciphisa isikhathi sokungasebenzi kokulinganisa endaweni ngo-60%. Umklamo wokulwa nokulayisha ngokweqile (kufika ku-5x full scale) kanye nokuvikela ukuphazamiseka kwe-electromagnetic (EMI) kuvikela ekukhuphukeni kwengcindezi nomsindo kagesi ovela emishinini yezimboni, okuqinisekisa ukuphuma okuzinzile ngisho nasezimweni zenqubo eziyinkimbinkimbi.​

Kusukela ekukhishweni kukawoyela ongaphezulu komfula kuya ekucutshungulweni kwamakhemikhali ongezansi komfula, lo mshini wokudlulisa udlula phambili ekulinganisweni kokugeleza, ukuqapha izinga, kanye nokulawula ingcindezi yamagesi, uketshezi, kanye nomhwamuko. Unciphisa ukuvalwa okungahleliwe, wehlisa izindleko zokulungisa, futhi uthuthukisa ukuphepha kokusebenza—okwenza kube ukukhetha okuthandwayo kwamabhizinisi e-petrochemical afuna ukunemba, ukuqina, kanye nokuhambisana nezindinganiso zemboni. Umklamo wawo omncane kanye nezinketho zokufaka eziguquguqukayo (i-flange, intambo, i-bracket) zivumelana kakhulu nokufakwa okuvinjelwe isikhala, ziletha ukusebenza okulinganayo kuzo zonke izindawo zokuhlanza, izitshalo zamakhemikhali, kanye namapulatifomu asogwini lolwandle.
