Kakaretso ea Sehlahisoa
Terata ea thermocouple ea Mofuta oa R ke thermocouple ea tšepe ea bohlokoa e nang le boleng bo holimo e entsoeng ka motsoako oa platinum-rhodium 13% (leoto le letle) le platinum e hloekileng (leoto le letle). Ke ea lelapa la thermocouple ea platinum-rhodium, e fanang ka botsitso le ho nepahala ho phahameng libakeng tse nang le mocheso o phahameng, haholo-holo pakeng tsa 1000°C le 1600°C. Ha e bapisoa le thermocouple ea Mofuta oa S, e na le rhodium e ngata leotong le letle, e fanang ka ts'ebetso e ntlafalitsoeng lits'ebetsong tsa mocheso o phahameng oa nako e telele.
Litlhophiso tse Tloaelehileng
- Mofuta oa Thermocouple: Mofuta oa R (Platinum-Rhodium 13-Platinum)
- Tekanyetso ea IEC: IEC 60584-1
- Tekanyetso ea ASTM: ASTM E230
Likarolo tsa Bohlokoa
- Ho tsitsa ha mocheso o phahameng: Mocheso oa ts'ebetso oa nako e telele ho fihlela ho 1400°C; tšebeliso ea nako e khuts'oane ho fihlela ho 1700°C
- Ho Nepahala ho Phahameng: Ho mamella ha Sehlopha sa 1 sa ±1.5°C kapa ±0.25% ea ho bala (ho sa tsotelehe hore na ke hofe ho hoholo)
- Sekhahla se Tlase sa ho Tsamaya: ≤0.05% thermoelectric potential drift kamora dihora tse 1000 ho 1200°C
- Ho Hanela Oxidation: Tshebetso e ntle haholo tikolohong e etsang oxidation le e sa sebetseng (qoba ho fokotsa tikoloho)
- Matla a Phahameng a Thermoelectric: E hlahisa 10.574 mV ho 1500°C (maqhubu a referense ho 0°C)

Likopo tse Tloaelehileng
- Teko ea enjene ea lifofane (likamore tsa ho chesa mocheso o phahameng)
- Lifono tsa indasteri tse nepahetseng haholo (ho siloa ha li-ceramic tse tsoetseng pele)
- Tlhahiso ea semiconductor (ho kenya li-silicon wafer)
- Patlisiso ea tšepe (teko ea ntlha ea ho qhibiliha ea superalloy)
- Tlhahiso ea faeba ea khalase (libaka tsa sebōpi tse nang le mocheso o phahameng)
Re boetse re fana ka li-probe tsa thermocouple tsa mofuta oa R, lihokelo, le lithapo tsa katoloso. Ka lebaka la boleng bo phahameng ba litšepe tsa bohlokoa, lisampole tsa mahala li fumaneha ka bolelele bo lekanyelitsoeng (≤1m) ha li kopuoa, ka litifikeiti tse qaqileng tsa thepa le litlaleho tsa tlhahlobo ea litšila.
