Mofuta oa B Thermocouple Wire
Kakaretso ea Sehlahisoa
Mofuta oa B oa mohala oa thermocouple ke tšepe ea bohlokoa ea tšepe ea boleng bo phahameng e nang le lisebelisoa tse peli tsa platinum-rhodium: leoto le nang le 30% rhodium le 70% platinum, le leoto le fosahetseng le 6% rhodium le 94% platinum. E etselitsoe maemo a mocheso o phahameng haholo, ke eona e mamellang mocheso ka ho fetisisa har'a li-thermocouples tsa bohlokoa tsa tšepe, e ipabolang ka botsitso le ho hanyetsa oxidation mocheso o fetang 1500 ° C. Sebopeho sa eona se ikhethang sa dual-platinum-rhodium se fokotsa ho hoholeha ho bakoang ke mouoane oa platinum, e leng se etsang hore e be se loketseng bakeng sa tekanyo ea nako e telele ea mocheso o phahameng.
Likhetho tse Tloaelehileng
- Mofuta oa Thermocouple: Mofuta oa B (Platinum-Rhodium 30-Platinum-Rhodium 6)
- Tekanyetso ea IEC: IEC 60584-1
- Boemo ba ASTM: ASTM E230
Likarolo tsa Bohlokoa
- Ho hanyetsa Mocheso o Feteletseng: Mocheso oa nako e telele oa ho sebetsa ho fihlela ho 1600 ° C; tšebeliso ea nako e khuts'oane ho fihlela ho 1800 ° C
- EMF e tlase ho Mocheso o Tlase: Phallo e nyane ea thermoelectric ka tlase ho 50 ° C, e fokotsa tšusumetso ea phoso ea mateano a batang.
- Botsitso bo Phahameng ba Mocheso o Phahameng: ≤0.1% ho hoholeha kamora lihora tse 1000 ho 1600°C
- Khanyetso ea Oxidation: Ts'ebetso e ntle haholo maemong a leholimo a oxidizing; e hanyetsanang le moyafalo wa platinum
- Matla a Mechini: E boloka ductility ka mocheso o phahameng, o loketseng maemo a thata a indasteri

Lisebelisoa tse Tloaelehileng
- Lisebelisoa tsa mocheso o phahameng oa mocheso (lisebelisoa tsa ceramic le refractory)
- Metal smelting (superalloy le tlhahiso e khethehileng ea tšepe)
- Ho etsa likhalase (likhalase tse phaphametseng li etsa libopi)
- Teko ea moea oa sefofane (li-nozzles tsa enjine ea rokete)
- Indasteri ea nyutlelie (ho hlahloba li-reactor tsa mocheso o phahameng)
Re fana ka likopano tsa mofuta oa B thermocouple tse nang le li-tubes tsa tšireletso tsa ceramic le likhokahano tsa mocheso o phahameng. Ka lebaka la boleng bo phahameng ba thepa, bolelele ba sampole bo lekanyelitsoe ho 0.5-1m ha bo kopuoa, bo tsamaea le litifikeiti tse felletseng tsa thepa le litlaleho tsa tlhahlobo ea litšila.
