Limeleng tsa lik'hemik'hale, ho lekanya maemo a mokelikeli ka nepo le ka ts'epo ho bohlokoa bakeng sa ho boloka ts'ebetso e bolokehileng le e sebetsang hantle.E 'ngoe ea li-sensor tse sebelisoang ka ho fetesisa tse hole tsa telemetry ke mochini o fetisang boemo ba mokelikeli o tsitsitseng.Mokhoa ona o lekanya boemo ba mokelikeli ka ho lekanya khatello e tsitsitseng ea kholomo ea mokelikeli ka sekepeng.Sehloohong sena, re tla tšohla lintlha tsa bohlokoa tsa khetho le maemo a ts'ebeliso ea sensor ea boemo ba metsi ea XDB502 lisebelisoa tsa lik'hemik'hale.
Likarolo le Melemo
Sensor ea boemo ba metsi ea XDB502 e na le likarolo tse 'maloa le melemo e etsang hore e tšoanelehe bakeng sa mefuta e mengata ea lits'ebetso ho limela tsa lik'hemik'hale.Tsena li kenyelletsa:
Ho sebetsa maemong a mocheso o phahameng, khatello e phahameng, viscosity e phahameng, le tikoloho e senyang haholo, e leng se etsang hore e tšoanelehe bakeng sa mefuta e mengata ea likopo.
Letoto le leholo la ho lekanya le fapaneng ho ea ka sebaka seo, 'me ha ho na matheba a foufetseng.
Ho tšepahala ho phahameng, botsitso, bophelo bo bolelele, le litšenyehelo tse tlaase tsa tlhokomelo.
Tekanyo e nepahetseng e phahameng, ka ho nepahala ho fihla ho +0.075% sekala se felletseng (fs) bakeng sa li-transmitters tsa boemo ba mokelikeli tse tsoang kantle ho naha le +0.25% fs bakeng sa li-transmitters tsa maemo a mokelikeli tse tloaelehileng tsa malapeng.
Ho itlhahloba ka bohlale le lits'ebetso tsa litlhophiso tse hole.
Likhetho tse fapaneng tsa tlhahiso ea mats'oao, ho kenyeletsoa liprothokholo tse fapaneng bakeng sa matšoao a hajoale a 4mA-20mA, matšoao a pulse, le matšoao a puisano a fieldbus.
Lintlha tsa Khetho
Ha u khetha transmitter ea static pressure fluid level, lintlha tse latelang li lokela ho nahanoa:
Haeba mofuta o lekanang (khatello e fapaneng) o le ka tlase ho 5KPa, 'me boima ba sekala se lekantsoeng bo fetoha ho feta 5% ea boleng ba moralo, ho se sebelisoe transmitter ea boemo ba mokelikeli bo fapaneng.
Ho chesa ha mokelikeli, ho phatloha, chefo, ho bola, ponahalo ea eona, ho ba teng ha likaroloana tse emisitsoeng, tšekamelo ea ho fetoha mouoane, le tšekamelo ea ho hopa ha mocheso oa tikoloho li lokela ho nahanoa ha ho khethoa transmitter.
Transmitter e ka etsoa ka li-flange tse le 'ngoe kapa tse peli.Bakeng sa li-transmitters tse peli tsa flange, bolelele ba capillary bo lokela ho lekana.
Bakeng sa lino tse atisang ho ba le kristale, sedimentation, viscosity e phahameng, coking, kapa polymerization, ho lokela ho khethoa mofuta oa diaphragm o fapaneng oa khatello ea boemo ba mokelikeli o nang le mokhoa oa ho tiisa.
Libakeng tseo mokhahlelo oa khase o khonang ho kokobetsa 'me karolo ea mokelikeli e ka fetoha mouoane,' me setshelo se tlas'a maemo a mocheso o phahameng le khatello e phahameng, ho lokela ho kengoa condenser, isolator le setshelo sa ho leka-lekana ha ho sebelisoa transmitter ea kamehla e fapaneng ea khatello ea boemo ba metsi bakeng sa. tekanyo ea boemo ba mokelikeli.
Transmitter ea 'nete e fapaneng ea boemo ba mokelikeli hangata e hloka phetoho e fapaneng.Ka hona, transmitter e lokela ho ba le mefuta e fapaneng ea ts'ebetso ea offset, 'me chelete ea offset e lokela ho ba bonyane 100% ea moeli o ka holimo oa mefuta.Ha u khetha transmitter, offset e lokela ho nahanoa, haholo-holo ha ho lekanya mecha ea litaba e phahameng haholo.Ka hona, mofuta oa transmitter o lokela ho khethoa ho ipapisitsoe le boemo ba offset.
Maemo a Tšebeliso
Sensor ea boemo ba metsi ea XDB502 e na le maemo a 'maloa a ts'ebeliso a lokelang ho nahanoa:
Mocheso oa mocheso: Mofuta ona oa transmitter o sebetsa ka ho fetisa khatello ka mokelikeli o tlatsang o tiisitsoeng ka har'a sesebelisoa.Lino tse tloaelehileng tsa ho tlatsa li kenyelletsa silicone ea 200, silicone ea 704, li-hydrocarbon tse chlorinated, metsoako ea glycerol le metsi, har'a tse ling.Mokelikeli o mong le o mong oa ho tlatsa o na le mocheso o loketseng oa mocheso, 'me mofuta oa ho tlatsa o lokela ho khethoa ho latela lik'hemik'hale tsa lik'hemik'hale tse lekantsoeng le mocheso oa ts'ebetso.Ka hona, ha mocheso oa ts'ebetso o feta 200 ℃, tšebeliso ea transmitter e tiisitsoeng ea diaphragm e lokela ho nahanoa ka hloko.Haeba ho hlokahala, ho lokela ho khethoa mokhoa o atolositsoeng oa ho tiisa kapa sesebelisoa sa ho ntlafatsa mocheso, 'me moetsi oa transmitter o lokela ho netefatsa lintlha.
Mocheso oa tikoloho: Mokelikeli o tlatsang o lokela ho tlatsoa ka mocheso o loketseng oa tikoloho.Capillary e tlameha ho bolokoa e lumellana le mocheso oa mokelikeli o tlatsang.Kaha epoxyethane e ka har'a lisebelisoa tsa EOEG tse ka chesoang ke ntho e tloaetseng ho etsa polymerization, ho lokela ho sebelisoe mochine o fetisang khatello ea metsi o tiisitsoeng ka diaphragm ho lekanya boemo ba seaplane sa epoxyethane.Ha litharollo tsa carbonate li le tšekamelo ea ho kristale, ho lokela ho sebelisoa mochine o fetisang mocheso o tiisitsoeng oa diaphragm o nang le mochini o tiisang oa ho kenya, 'me ntlha ea ho kenya e ts'oaroe le lebota le kahare la sesebelisoa.Sekhahla sa ka ntle le bolelele ba ho kenya li khethoa ho latela lintlha tsa thepa.Bakeng sa lisebelisoa tse nang le mocheso oa ho sebetsa oa moropa oa 250 ℃ kapa ho feta, lipeipi tsa khatello tse tloaelehileng li lokela ho sebelisoa.
Qetello
Qetellong, sensor ea boemo ba metsi ea XDB502 ke khetho e tšepahalang le e nepahetseng ea ho lekanya maemo a mokelikeli limela tsa lik'hemik'hale.E na le melemo e mengata, ho kenyelletsa le mefuta e mengata e fapaneng, ho nepahala ho phahameng, likhetho tse fapaneng tsa tlhahiso ea matšoao, le ho itlhahloba ka bohlale.Ha ho khethoa mochine o fetisang molaetsa, ho lokela ho nahanoa ka litšobotsi tsa mokelikeli ona, tse kang ho cha, ho phatloha, chefo, ho bola le viscosity.Ho feta moo, maemo a ts'ebeliso joalo ka mocheso oa ts'ebetso le mocheso oa tikoloho a lokela ho tsotelloa ho netefatsa litekanyo tse nepahetseng le tse tšepahalang.
