Thermocouples ke lisebelisoa tsa bohlokoa tsa ho lekanya mocheso liindastering tse fapaneng. Har'a mefuta e fapaneng, li-thermocouples tsa platinum-rhodium li hlahella ka lebaka la ts'ebetso ea tsona e phahameng ea mocheso le ho nepahala. Sengoliloeng sena se tla shebisisa lintlha tsa platinum-rhodium thermocouples, ho kenyelletsa le ts'ebeliso ea tsona, terata e ntle ka ho fetisisa ea thermocouple, le sebopeho sa S-type thermocouples.
Ke mefuta efe ea platinum-rhodium thermocouples?
Ho na le mefuta e meraro ea mantlha eaplatinum-rhodium thermocouples: Mofuta oa B, mofuta oa R, le mofuta oa S. Li-thermocouples tsena li tsejoa ka botsitso ba tsona ba mocheso o phahameng 'me hangata li sebelisoa lits'ebetsong tse hlokang tekanyo e nepahetseng ea mocheso.
1. Mofuta oa B (Platinum 30% Rhodium / Platinum 6% Rhodium): Mocheso oa mocheso: 0 ° C ho 1700 ° C, Likarolo: Li-thermocouples tsa Mofuta oa B li tsitsitse haholo 'me li ka lekanya mocheso o phahameng haholo. Hangata e sebelisoa liboping tsa mocheso o phahameng oa mocheso le li-kilns.
2. Mofuta oa R (Platinum 13% Rhodium / Platinum): Mocheso oa mocheso: -50 ° C ho 1600 ° C, Likarolo: Mofuta oa R thermocouples o etsa hore ho be le tekanyo e ntle pakeng tsa litšenyehelo le ts'ebetso. Li sebelisoa lits'ebetsong tse fapaneng tsa indasteri ho kenyelletsa tlhahiso ea likhalase le ts'ebetso ea tšepe.
3. Mofuta oa S (Platinum 10% Rhodium / Platinum): Mocheso oa mocheso: -50 ° C ho 1600 ° C, Likarolo: Mofuta oa S thermocouples o tsejoa ka ho nepahala le botsitso. Hangata li sebelisoa lilaboratoring le liindastering moo ho leng bohlokoa ho laola mocheso ka nepo.
terata e ntle ka ho fetisisa ea thermocouple ke efe?
Sepheo sa ho ahlola boleng ba sehlahisoa se itšetlehile ka boleng ba sona. Lihlahisoa tse fapaneng li na le litekanyetso tse fapaneng tsa boleng, 'me boleng ba terata ea thermocouple ea platinum-rhodium bo ka ahloloa ho tloha ho tse' nè tse latelang. Ntlha ea pele, terata ea platinum-rhodium e na le botsitso bo phahameng ba mocheso 'me e khona ho mamella mocheso o phahameng haholo ntle le ho senyeha. Botsitso bona bo netefatsa tekanyo e nepahetseng ea mocheso holim'a mefuta e mengata ea mocheso. Ea bobeli, li-thermocouples tsa platinum-rhodium li fana ka tekanyo e nepahetseng ea mocheso, e etsang hore e be e loketseng bakeng sa lisebelisoa tse hlokang ho nepahala ho tiileng. Ntle le moo, platinum le rhodium le tsona li na le khanyetso e phahameng ea kutu, e netefatsa bophelo ba ts'ebeletso le ts'epahalo ea terata ea thermocouple libakeng tse thata. Ho tšoarella ha terata ea platinum-rhodium thermocouple ho etsa hore e tšoanelehe bakeng sa tšebeliso ea nako e telele lits'ebetsong tsa indasteri, ho fokotsa tlhoko ea ho nkela sebaka khafetsa. Haeba litlhoko tsa ho nepahala ha tekanyo, botsitso, ho hanyetsa oxidation, joalo-joalo li phahame haholo, terata ea platinum-rhodium thermocouple ke khetho e ntle ka ho fetisisa.
Tšebeliso ea terata ea platinum thermocouple ke efe?
terata ea thermocouple ea platinamuke karolo ea bohlokoa kahong ea platinum-rhodium thermocouples. Thepa ea eona e ikhethang e etsa hore terata ea platinum-rhodium thermocouple e loketse mefuta e fapaneng ea likopo tsa mocheso o phahameng. Lefapheng la lifofane, terata ea platinum thermocouple e sebelisoa ho lekanya mocheso oa lienjineri tsa jete le likarolo tse ling tsa mocheso o phahameng. Tekanyo e nepahetseng ea mocheso e bohlokoa bakeng sa polokeho le ts'ebetso ea lisebelisoa tsa sefofane. Platinum thermocouple terata e sebelisoa liboping tsa indasteri ho lekola le ho laola mocheso o phahameng. Ho tsitsa ha bona le ho nepahala ha bona ho netefatsa hore sebōpi se sebetsa ka har'a mocheso o hlokahalang, kahoo ho ntlafatsa katleho le boleng ba sehlahisoa. Ntle le moo, ts'ebetso ea tlhahiso ea likhalase e hloka taolo e nepahetseng ea mocheso, 'me terata ea platinum thermocouple e sebelisoa ho lekola mocheso oa libopi tsa khalase ho netefatsa tlhahiso e tsitsitseng le ea boleng bo holimo. Lipatlisisong tsa mahlale, tekanyo e nepahetseng ea mocheso e bohlokoa bakeng sa liteko le pokello ea lintlha. Platinum thermocouple terata e sebelisoa ho lekanya mocheso litekong tse fapaneng ka laboratoring, e fana ka lintlha tse tšepahalang le tse nepahetseng.
Platinum-rhodium thermocouples (ho kenyeletsoa mefuta ea B, R, le S) ke lisebelisoa tsa bohlokoa tsa ho lekanya mocheso ka nepo lits'ebetsong tse phahameng tsa mocheso. Ha u khetha mohala o motle ka ho fetisisa oa thermocouple, platinum-rhodium thermocouples hangata ke khetho ea pele hobane e sebetsa hantle libakeng tse thata. Platinum-rhodium thermocouples e phetha karolo ea bohlokoa liindastering tse fapa-fapaneng, ho fana ka ho nepahala le botsitso bo hlokahalang bakeng sa likopo tse phahameng tsa mocheso.
