Type B Thermocouple Waya
Zowonetsa Zamalonda
Waya wa mtundu B wa thermocouple ndizitsulo zamtengo wapatali zamtengo wapatali zomwe zimakhala ndizitsulo ziwiri za platinamu-rhodium: mwendo wabwino wokhala ndi 30% rhodium ndi 70% platinamu, ndi mwendo woipa wokhala ndi 6% rhodium ndi 94% platinamu. Zopangidwira malo otentha kwambiri, ndizosatentha kwambiri pakati pa ma thermocouples amtengo wapatali azitsulo, zomwe zimapambana kwambiri pakukhazikika komanso kukana kwa okosijeni pa kutentha kopitilira 1500 ° C. Mapangidwe ake apadera a platinamu-rhodium amachepetsa kugwedezeka komwe kumachitika chifukwa cha kuphulika kwa platinamu, ndikupangitsa kuti ikhale yoyenera kuyeza kutentha kwanthawi yayitali.
Maudindo Okhazikika
- Mtundu wa Thermocouple: B-mtundu (Platinum-Rhodium 30-Platinum-Rhodium 6)
- Muyezo wa IEC: IEC 60584-1
- Muyezo wa ASTM: ASTM E230
- Kujambula kwamtundu: Mwendo wabwino - imvi; Mwendo wopanda pake - woyera (pa IEC 60751)
Zofunika Kwambiri
- Kukaniza Kutentha Kwambiri: Kutentha kwa nthawi yayitali mpaka 1600 ° C; kugwiritsa ntchito kwakanthawi kochepa mpaka 1800 ° C
- EMF Yotsika Pakutentha Kochepa: Kutulutsa kochepa kwa thermoelectric pansi pa 50 ° C, kuchepetsa vuto la kuzizira kozizira
- Kukhazikika Kwapamwamba Kwambiri: ≤0.1% kusuntha pambuyo pa maola 1000 pa 1600 ° C
- Kukaniza kwa Oxidation: Kuchita bwino kwambiri mumlengalenga wa okosijeni; kukana kuphulika kwa platinamu
- Mphamvu zamakina: Imasunga ductility pa kutentha kwakukulu, koyenera kumadera ovuta a mafakitale
Mfundo Zaukadaulo
| Malingaliro | Mtengo |
|---|---|
| Waya Diameter | 0.5mm, 0.8mm, 1.0mm (kulekerera: -0.02mm) |
| Mphamvu ya Thermoelectric (1000°C) | 0.643 mV (vs 0°C reference) |
| Mphamvu ya Thermoelectric (1800°C) | 13.820 mV (vs 0°C reference) |
| Kutentha kwa Nthawi Yaitali | 1600 ° C |
| Kutentha Kwakanthawi kochepa | 1800°C (≤10 maola) |
| Kulimba Kwambiri (20°C) | ≥150 MPa |
| Elongation | ≥20% |
| Kukanika kwa Magetsi (20°C) | Mwendo wabwino: 0.31 Ω · mm²/m; Mwendo woipa: 0.19 Ω·mm²/m |
Mapangidwe a Chemical (Zomwe, %)
| Kondakitala | Zinthu Zazikulu | Tsatirani Zinthu (zochuluka, %) |
|---|---|---|
| Mwendo Wabwino (Platinum-Rhodium 30) | Pt:70, Rh:30 | Ir:0.02, Ru:0.01, Fe:0.003, Cu:0.001 |
| Mwendo Woipa (Platinum-Rhodium 6) | Pt:94, Rh:6 | Ir:0.02, Ru:0.01, Fe:0.003, Cu:0.001 |
Zofotokozera Zamalonda
| Kanthu | Kufotokozera |
|---|---|
| Utali pa Spool | 5m, 10m, 20m (chifukwa cha zitsulo zamtengo wapatali) |
| Pamwamba Pamwamba | Zowala, zowala (palibe kuipitsidwa pamwamba) |
| Kupaka | Vacuum-zosindikizidwa mu zotengera za titaniyamu zodzaza ndi argon kuti mupewe okosijeni |
| Kuwongolera | Kutsatiridwa ku miyezo ya kutentha kwapadziko lonse yokhala ndi ma curve otsimikizika a EMF |
| Zokonda Mwamakonda | Kudula mwatsatanetsatane, kupukuta pamwamba pa ntchito zoyera kwambiri |
Ntchito Zofananira
- ng'anjo zotentha kwambiri (za ceramic ndi refractory)
- Kusungunula zitsulo (superalloy ndi kupanga zitsulo zapadera)
- Kupanga magalasi (magalasi oyandama kupanga ng'anjo)
- Kuyesa kwamlengalenga (kuyesa kwa injini ya rocket)
- Makampani a nyukiliya (kuwunika kwa kutentha kwapamwamba)
Timapereka magulu amtundu wa B thermocouple okhala ndi machubu achitetezo a ceramic ndi zolumikizira kutentha kwambiri. Chifukwa cha kukwera kwa zinthu, kutalika kwa zitsanzo kumangokhala 0.5-1m pofunsidwa, kutsagana ndi ziphaso zonse zakuthupi ndi malipoti osanthula zonyansa. Zosintha mwamakonda za malo enieni a ng'anjo zilipo.
