Kakaretso ea Sehlahisoa
Tšepe ea bohlokoa
terata ea thermocouple Mofuta oa S, e tsejoang hape e le Platinum-Rhodium 10-Platinum
terata ea thermocouple, ke karolo e lemohang mocheso ka nepo e entsoeng ka di-conductor tse pedi tsa tshepe ya bohlokwa. Leoto le letle (RP) ke motswako wa platinum-rhodium o nang le 10% ya rhodium le 90% ya platinum, ha leoto le letle (RN) e le platinum e hlwekileng. E fana ka ho nepahala le botsitso bo ikgethang dibakeng tse nang le mocheso o phahameng, e leng se etsang hore e be kgetho e kgethwang bakeng sa tekanyo e nepahetseng ya mocheso ho metallurgy, ceramics le diontong tsa indasteri tse nang le mocheso o phahameng.
Litlhophiso tse Tloaelehileng
- Mofuta oa Thermocouple: Mofuta oa S (Platinum-Rhodium 10-Platinum)
- Tekanyetso ea IEC: IEC 60584-1
- Tekanyetso ea ASTM: ASTM E230
- Ho ngola mmala: Leoto le letle - le letala; Leoto le letle - le lesweu (ho ya ka maemo a IEC)
Likarolo tsa Bohlokoa
- Mefuta e Meholo ea Mocheso: Tšebeliso ea nako e telele ho fihlela ho 1300°C; tšebeliso ea nako e khuts'oane ho fihlela ho 1600°C
- Ho Nepahala ho Hoholo: Ho nepahala ha Sehlopha sa 1 ka mamello ea ±1.5°C kapa ±0.25% ea ho bala (ho sa tsotelehe hore na ke hofe ho hoholo)
- Ho tsitsa ho Hlollang: Ho theoha ha matla a thermoelectric ka tlase ho 0.1% kamora lihora tse 1000 ho 1000°C
- Khanyetso e Ntle ea Oxidation: Tshebetso e tsitsitseng sepakapakeng se oxidation le se sa sebetseng
- Bokgoni bo Tlase ba Thermoelectric: E hlahisa 6.458 mV ho 1000°C (maqhubu a referense ho 0°C)
