Mefuta ea li-thermocouple tsa platinum-rhodium ke efe?
Ho na le mefuta e meraro e meholo eali-thermocouple tsa platinum-rhodium: Mofuta oa B, mofuta oa R, le mofuta oa S. Li-thermocouple tsena li tsebahala ka botsitso ba tsona mochesong o phahameng 'me hangata li sebelisoa lits'ebetsong tse hlokang tekanyo e nepahetseng ea mocheso.
1. Mofuta wa B (Platinum 30% Rhodium/Platinum 6% Rhodium): Maemo a mocheso: 0°C ho isa ho 1700°C, Dibopeho: Di-thermocouple tsa Mofuta wa B di tsitsitse haholo mme di ka lekanya dithempereichara tse phahameng haholo. Hangata di sebediswa diontong le diontong tse nang le mocheso o phahameng.
2. Mofuta wa R (Platinum 13% Rhodium/Platinum): Maemo a mocheso: -50°C ho isa ho 1600°C, Dibopeho: Di-thermocouple tsa Mofuta wa R di na le tekano e ntle pakeng tsa ditjeo le tshebetso. Di sebediswa dikopong tse fapaneng tsa indasteri ho kenyeletswa tlhahiso ya khalase le ts'ebetso ya tshepe.
3. Mofuta wa S (Platinum 10% Rhodium/Platinum): Maemo a mocheso: -50°C ho isa ho 1600°C, Dibopeho: Di-thermocouple tsa Mofuta wa S di tsebahala ka ho nepahala le botsitso ba tsona. Di sebediswa hangata dilaboratoring le diindastering moo taolo e nepahetseng ya mocheso e leng bohlokwa.
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 tsoa litšobotsing tse 'ne tse latelang. Ea pele, terata ea platinum-rhodium e na le botsitso bo phahameng ba mocheso 'me e ka mamella mocheso o phahameng haholo ntle le ho senyeha. Botsitso bona bo netefatsa tekanyo e nepahetseng ea mocheso holim'a mocheso o pharaletseng. Ea bobeli, li-thermocouple tsa platinum-rhodium li fana ka tekanyo e nepahetseng ea mocheso, e leng se etsang hore li be ntle bakeng sa lits'ebetso tse hlokang ho nepahala ho tiileng.

Tšebeliso ea terata ea thermocouple ea platinum ke efe?
Terata ea thermocouple ea Platinumke karolo ea bohlokoa kahong ea li-thermocouple tsa platinum-rhodium. Thepa ea eona e ikhethang e etsa hore terata ea platinum-rhodium thermocouple e lokele mefuta e fapaneng ea lits'ebetso tsa mocheso o phahameng. Indastering ea lifofane, terata ea platinum thermocouple e sebelisoa ho lekanya mocheso oa lienjine tsa jet le likarolo tse ling tsa mocheso o phahameng. Tekanyo e nepahetseng ea mocheso e bohlokoa bakeng sa polokeho le ts'ebetso ea lisebelisoa tsa lifofane. Terata ea platinum thermocouple e sebelisoa lifonong tsa indasteri ho lekola le ho laola mocheso o phahameng. Ho tsitsa ha tsona le ho nepahala ha tsona ho netefatsa hore sebopi se sebetsa ka har'a mocheso o hlokahalang, ka hona ho ntlafatsa katleho le boleng ba sehlahisoa. Ho phaella moo, ts'ebetso ea tlhahiso ea khalase e hloka taolo e nepahetseng ea mocheso, 'me terata ea platinum thermocouple e sebelisoa ho lekola mocheso oa lifono tsa khalase ho netefatsa tlhahiso ea khalase e tsitsitseng le ea boleng bo holimo. Phuputsong ea saense, tekanyo e nepahetseng ea mocheso e bohlokoa bakeng sa liteko le pokello ea data. Terata ea platinum thermocouple e sebelisoa ho lekanya mocheso litekong tse fapaneng laboratoring, e fana ka data e tšepahalang le e nepahetseng.
Li-thermocouple tsa platinum-rhodium (ho kenyeletsoa mefuta ea B, R, le S) ke lisebelisoa tsa bohlokoa bakeng sa ho lekanya mocheso ka nepo lits'ebetsong tsa mocheso o phahameng. Ha ho khethoa terata e ntle ka ho fetisisa ea thermocouple, li-thermocouple tsa platinum-rhodium hangata ke khetho ea pele hobane li sebetsa hantle libakeng tse thata. Li-thermocouple tsa platinum-rhodium li bapala karolo ea bohlokoa liindastering tse fapaneng, li fana ka ho nepahala le botsitso bo hlokahalang bakeng sa lits'ebetso tsa mocheso o phahameng.
