Ama-pressure transmitterNgokuvamile zenzelwe ukuqoqwa kwedatha ezisetshenziswa emkhakheni wezimboni, ezikwazi ukukhipha izimpawu ezijwayelekile futhi zinikeze izinhlelo zokulawula idatha yokulinganisa ezinzile nethembekile. Ngokombono wezimiso zokulinganisa, ingcindezi yendawo elinganisiwe akuyona nje ipharamitha yenqubo ehlukanisiwe—empeleni ibonisa izici ezihlanganisiwe zoketshezi oluphakathi ngaphansi kwezimo ezimile nezishintshashintshayo. Ngokusebenzisa ngokugcwele ubudlelwano obungaphakathi, kungenzeka ukuthola amapharamitha enqubo abalulekile njengezinga loketshezi kanye nesilinganiso sokugeleza ezilinganisweni zomthumeli wokucindezela ngaphandle kokwengeza izinzwa ezengeziwe. Inzuzo eyingqayizivele yenza abathumeli bokucindezela babaluleke kakhulu lapho kwakhiwe izixazululo zokulinganisa ezinokwethenjelwa kakhulu ezinhlelweni zezimboni eziyinkimbinkimbi.
Ukulinganiswa Kwezinga Lokucindezela Okungaguquki
Kuketshezi olungashintshi, ingcindezi engaguquki kunoma yikuphi ukujula ingachazwa ngefomula yengcindezi yoketshezi P = ρgh. Ngokusekelwe esimisweni, isignali yokukhipha yomthumeli wengcindezi ibonisa ubudlelwano obuqondile nokuphakama kwezinga loketshezi. Indlela yokulinganisa ifaneleka kakhulu ezimweni zokusebenza eziyinkimbinkimbi kanye nezinhlelo zokusebenza ezidinga impendulo esheshayo. Lolu hlobo lokulinganisa lungasetshenziswa kabanzi ezimweni ezifana namathangi okugcina amakhemikhali, imikhumbi yokubilisa imithi kanye nama-sump amanzi amdaka kamasipala.
Ezisetshenzisweni zezimboni,ama-transmitter asezingeni lokucwiliswakanye nama-pressure transmitter avamile asebenza ngesimiso sokulinganisa ingcindezi engaguquki, kodwa ahlukile ngesakhiwo, ukufakwa kanye nezimo ezifanele. Ama-transmitter asezingeni elingaphansi komhlaba aqinile futhi kulula ukuwafaka, kanti i-sensor probe ibekwa phansi koketshezi isikhathi eside. Afaneleka kakhulu ezindaweni ezifana nemithombo ejulile, amathangi amanzi kanye nemikhumbi yokugcina evulekile. Ama-pressure transmitter afakwa ngaphandle komkhumbi futhi angaphatha amazinga okushisa aphezulu kanye nezinqubo zokuhlanzeka ngezinyathelo ezifana naleziuphawu lwe-diaphragmkanye ne-capillary ekude.
Ukulinganisa Izinga Lokucindezela Okuhlukile
Esitsheni esivaliwe esinengcindezi yesigaba segesi eshintshashintshayo, ukusebenzisa i-pressure transmitter kuphela kuveza isamba sengcindezi ye-hydrostatic kanye nengcindezi yesigaba segesi, engakwazi ukukhombisa izinga langempela loketshezi. Ngakho-ke, i-umshini wokudlulisa ingcindezi ehlukile (DP)kufanele kusetshenziswe, kuxhumaniswe uhlangothi olunengcindezi ephezulu phansi (ingcindezi engaguquki + ingcindezi yesigaba segesi) kanye nohlangothi olunengcindezi ephansi phezulu (ingcindezi yesigaba segesi kuphela). Ngokubala umehluko wengcindezi, ukuphazamiseka okuvela ekucindezelweni kwesigaba segesi kuyasuswa, kuveze isignali ehambisana kuphela nezinga loketshezi. Lolu hlobo lokulinganisa lusetshenziswa kabanzi kuma-reactor amakhemikhali, amakholomu okuhluza kanye nezinye izinhlelo zokusebenza lapho kudingeka khona ukulawulwa kwezinga elizinzile ngaphansi kwezimo ezicindezelwe. Ukuze uthole izinga lokushisa eliphezulu kanye nemidiya enamandla,uhlelo lwe-capillary olune-flange ezimbilingokuvamile ilungiselelwe ukuhlukanisa indlela yokusebenza ekuxhumaneni ngqo nesici sokuzwa, ngaleyo ndlela ithuthukise ukuzinza kwesikhathi eside kwethuluzi ezimweni ezimbi kakhulu.
Ukulinganisa Ukugeleza Kokucindezela Okuhlukile
Isisekelo sokulinganisa ukugeleza kwe-DP ukuthi lapho uketshezi lugeleza kudivayisi yokugoqa (ipuleti le-orifice, i-annubar, njll.), ukuhlukahluka kwesigaba sokugeleza kubangela ijubane lokugeleza ukuthi lishintshe ngokufanele futhi kudale umehluko wokucindezela kuyo yonke into yokugoqa enobudlelwano obusebenzayo obuchazwe kahle nesilinganiso sokugeleza. Ngokulinganisa ngokunembile umehluko wokucindezela nge-DP transmitter, izinga lokugeleza linganqunywa ngokungaqondile. Ngenxa yezinga lalo eliphezulu lokuma, ukuzivumelanisa nezimo okuhle kakhulu, kanye nokufaneleka ngaphansi kwezimo eziyinkimbinkimbi,Ama-flowmeter asekelwe ku-DPbamba isikhundla esingenakufakwa esikhundleni ekulinganisweni kokugeleza komusi kanye namagesi nge-transmitter yokucindezela okuhlukile idlala indima ebalulekile njengesici sokuzwa okuyinhloko.
Isithumeli sokucindezela akuyona neze idivayisi enikeza ukufunda nje kuphela, inani layo langempela lisekuchazeni okujulile kanye nokusetshenziswa okuguquguqukayo kwedatha yokulinganisa. Ukuqonda ngokugcwele nokusebenzisa ngobuhlakani ubudlelwano obungokoqobo obungemuva kwedatha yokulinganisa ingcindezi kungavula izindlela ezisebenza kahle nezinembile zokulawula izinqubo kanye nokwenza ngcono uhlelo. Uchwepheshe ekukhiqizweni nasekuhlinzekweni kwezinsimbi iminyaka engaphezu kwengu-20,Shanghai Wangyuanizimisele ukuhlinzeka amakhasimende ngemikhiqizo nezinsizakalo ezizinzile nezithembekile. Kungakhathaliseki ukuthi unezidingo noma imibuzo mayelana nokukhetha noma ukusetshenziswa kwama-pressure transmitters, sicela ukhululeke ukuxhumana nathi. Sizojabula ukukunikeza izixazululo zobungcweti nezifika ngesikhathi.
