Tankii Manufacture fiilada heerkulbeegga ah nooca B PtRh30-PtRh6
Sharaxaada Alaabta
Nooca B Thermocouple Wire
Dulmarka alaabta
Silig heerkulbeegeedka nooca B waa heerkulbeeg heersare ah oo bir ah oo qiimo leh oo ka kooban laba alwaax oo platinum-rhodium ah: lug togan oo leh 30% rhodium iyo 70% platinum, iyo lug taban oo leh 6% rhodium iyo 94% platinum. Naqshadeynta jawi heerkul sare oo aad u sarreeya, waa kulaylka ugu adkeysi badan marka loo eego heerkulbeegyada birta ee qaaliga ah ee caadiga ah, oo aad ugu sarreeya xasilloonida iyo iska caabinta oksaydhka heerkulka ka sarreeya 1500 ° C. Halabuurka laba-platinum-rhodium gaar ah wuxuu yareeyaa qulqulka uumi-baxa platina, taasoo ka dhigaysa mid ku habboon cabbirka heerkulka sare ee muddada-dheer.
Naqshadaynta caadiga ah
- Nooca Thermocouple: Nooca B (Platinum-Rhodium 30-Platinum-Rhodium 6)
- Heerka IEC: IEC 60584-1
- Heerka ASTM: ASTM E230
- Codaynta Midabka: Lugta wanaagsan - cawl; Lugta taban - cad (halkii IEC 60751)
Tilmaamaha Muhiimka ah
- Cadaadiska Heerkulka Ba'an: heerkulka shaqaynta muddada-dheer ilaa 1600 ° C; isticmaalka muddada-gaaban ilaa 1800 ° C
- EMF hoose ee Heerkulka Hoose: Soosaarka heerkulbeegga ugu yar ee ka hooseeya 50°C, yaraynta saamaynta khaladka isgoysyada qabow
- Deganaanshaha Heer Sare ee Sare: ≤0.1% leexleexad kadib 1000 saacadood at 1600°C
- Resistance Oxidation: Waxqabadka aad u fiican ee jawiga oksaydheynta; adkaysi u leh uumiga platinum
- Xoogga Makaanikada: Waxay ilaalisaa ductility heerkulka sare, oo ku habboon bay'ada warshadaha qallafsan

Codsiyada caadiga ah
- Foornooyinka kululaynta heerkulkiisu sarreeyo
- Dhalinta birta (superalloy iyo birta gaarka ah)
- Wax-soo-saarka dhalooyinka (Furnada dhalada sabaynaysa)
- Tijaabada kicinta hawada (matoorada gantaallada)
- Warshadaha Nukliyeerka (la socoshada kicinta heerkulka sare)
Waxa aanu bixinaa nooca B ee isku xidha heerkulbeegyada tuubooyinka ilaalinta dhoobada iyo xidhayaasha heerkul sare. Qiimaha alaabta oo sarreeya awgeed, dhererka muunadku waxay ku xaddidan yihiin 0.5-1m marka la codsado, oo ay la socdaan shahaado buuxda iyo warbixinnada falanqaynta wasakhda. Habaynta gaarka ah ee jawiyada foornada gaarka ah ayaa diyaar ah.
