Iru B Thermocouple Waya
ọja Akopọ
Iru okun thermocouple B jẹ thermocouple irin iyebiye ti o ni iṣẹ giga ti o ni awọn alloy Platinum-rhodium meji: ẹsẹ rere pẹlu 30% rhodium ati 70% Pilatnomu, ati ẹsẹ odi pẹlu 6% rhodium ati 94% Pilatnomu. Ti a ṣe apẹrẹ fun awọn agbegbe iwọn otutu ti o ga julọ, o jẹ sooro ooru julọ laarin awọn thermocouples irin iyebiye, ti o tayọ ni iduroṣinṣin ati resistance ifoyina ni awọn iwọn otutu ti o kọja 1500°C. Apapọ pilatnomu-rhodium alailẹgbẹ rẹ dinku idinku ti o ṣẹlẹ nipasẹ evaporation Pilatnomu, ti o jẹ ki o jẹ apẹrẹ fun wiwọn iwọn otutu igba pipẹ.
Standard Designations
- Thermocouple Iru: B-Iru (Platinum-Rhodium 30-Platinum-Rhodium 6)
- IEC Standard: IEC 60584-1
- ASTM Standard: ASTM E230
- Ifaminsi awọ: Ẹsẹ to dara - grẹy; Ẹsẹ odi – funfun (fun IEC 60751)
Key Awọn ẹya ara ẹrọ
- Resistance Awọn iwọn otutu to gaju: iwọn otutu iṣiṣẹ igba pipẹ titi de 1600 ° C; lilo igba diẹ to 1800°C
- EMF kekere ni Awọn iwọn otutu kekere: Ijade thermoelectric ti o kere ju ni isalẹ 50°C, idinku ipa ašiše ọna asopọ tutu
- Iduroṣinṣin iwọn otutu giga: ≤0.1% fiseete lẹhin awọn wakati 1000 ni 1600°C
- Resistance Oxidation: Iṣẹ ti o dara julọ ni awọn agbegbe oxidizing; sooro si Pilatnomu evaporation
- Agbara Mechanical: Ṣe itọju ductility ni awọn iwọn otutu giga, o dara fun awọn agbegbe ile-iṣẹ lile
