Ụdị B Thermocouple Waya
Nchịkọta ngwaahịa
Ụdị waya thermocouple B bụ thermocouple metal dị oke ọnụ ahịa dị elu nke nwere ihe abụọ platinum-rhodium: ụkwụ dị mma nwere 30% rhodium na 70% platinum, na ụkwụ na-adịghị mma nwere 6% rhodium na 94% platinum. Ezubere ya maka gburugburu oke okpomọkụ dị elu, ọ bụ ihe na-ekpo ọkụ kachasị n'etiti igwe ọkụ ọkụ metal dị oke ọnụ ahịa, na-enwe oke nkwụsi ike na nguzogide oxidation na okpomọkụ karịrị 1500°C. Ngwakọta ya abụọ-platinum-rhodium pụrụ iche na-ebelata mkpagharị nke evaporation platinum kpatara, na-eme ka ọ dị mma maka nleba okpomọkụ dị elu ogologo oge.
Ụkpụrụ ọkọlọtọ
- Ụdị Thermocouple: Ụdị B (Platinum-Rhodium 30-Platinum-Rhodium 6)
- IEC ọkọlọtọ: IEC 60584-1
- Ụkpụrụ ASTM: ASTM E230
Atụmatụ igodo
- Nguzogide oke okpomọkụ: Ogologo oge na-arụ ọrụ ruo 1600 ° C; eji obere oge eme ihe ruo 1800 Celsius
- EMF dị ala na Okpomọkụ dị ala: Opekempe thermoelectric dị n'okpuru 50 Celsius, na-ebelata mmetụta njehie nkwụsị oyi
- Nkwụsi ike dị elu dị elu: ≤0.1% na-efegharị mgbe awa 1000 gachara na 1600°C
- Nguzogide Oxidation: Ọrụ dị oke mma na ikuku oxidizing; na-eguzogide evaporation platinum
- Ike Mechanical: Na-ejigide ductility na oke okpomọkụ, dabara maka gburugburu ụlọ ọrụ siri ike
