I-PtRh13-Pt R-Type Thermocouple I-Ultra-Precise High-Temp Sensing kunye ne-Steady Thermal Response
Ingcaciso yeMveliso
Uhlobo R Thermocouple Wire
Isishwankathelo seMveliso
Intambo ye-thermocouple yohlobo lwe-R yi-thermocouple yesinyithi exabisekileyo echanekileyo kakhulu eyenziwe yi-platinum-rhodium 13% alloy (umlenze olungileyo) kunye neplatinum ecocekileyo (umlenze ongalunganga). Iphantsi kosapho lwe-thermocouple yeplatinum-rhodium, enika uzinzo oluphezulu kunye nokuchaneka kwiindawo ezinobushushu obuphezulu, ingakumbi kuluhlu lwe-1000°C ukuya kwi-1600°C. Xa ithelekiswa ne-thermocouples yohlobo lwe-S, inomxholo ophezulu we-rhodium kwi-positive leg, ebonelela ngokusebenza okuphuculweyo kwizicelo zobushushu obuphezulu bexesha elide.
Iimpawu eziQhelekileyo
- Uhlobo lweThermocouple: Uhlobo lwe-R (iPlatinum-Rhodium 13-Platinum)
- Umgangatho we-IEC: IEC 60584-1
- Umgangatho we-ASTM: ASTM E230
Ezona mpawu
- Uzinzo lobushushu obuphezulu: Ubushushu bokusebenza bexesha elide ukuya kuthi ga kwi-1400°C; ukusetyenziswa kwexesha elifutshane ukuya kuthi ga kwi-1700°C
- Ukuchaneka Okuphezulu: Ukunyamezela kweKlasi 1 ye-±1.5°C okanye i-±0.25% yokufunda (nokuba yeyiphi na enkulu)
- Izinga lokuKhupha eliphantsi: ≤0.05% ukukhupha okunokwenzeka kwe-thermoelectric emva kweeyure ezili-1000 kwi-1200°C
- Ukumelana ne-Oxidation: Ukusebenza kakuhle kakhulu kwi-oxidizing kunye ne-intillery atmospheres (kuphephe ukunciphisa iindawo)
- Amandla aphezulu eThermoelectric: Ivelisa i-10.574 mV kwi-1500°C (i-reference junction kwi-0°C)

| Ukupakisha | Ivalwe nge-vacuum kwiikhonteyina ezizaliswe yi-argon ukuthintela ungcoliseko |
| Ukulinganisa | I-NIST-inokulandeleka kunye nesatifikethi se-thermoelectric potential |
| Iinketho Zesiko | Ukucoca okulinganiselweyo, okukhethekileyo kokusetyenziswa kobunyulu obuphezulu kakhulu |
Izicelo eziqhelekileyo
- Uvavanyo lweenjini zeenqwelo-moya (amagumbi okutsha anobushushu obuphezulu)
- Izitofu zoshishino ezichanekileyo kakhulu (ukutshiza izinto zodongwe eziphucukileyo)
- Ukwenziwa kwee-semiconductor (ukufakelwa kwe-silicon wafer)
- Uphando lweMetallurgical (uvavanyo lwe-superalloy melting point)
- Imveliso yefayibha yeglasi (iindawo zesithando somlilo esinobushushu obuphezulu)
Sikwabonelela ngee-probe ze-thermocouple zohlobo lwe-R, izihlanganisi, kunye neentambo zokwandisa. Ngenxa yexabiso eliphezulu leentsimbi ezixabisekileyo, iisampulu zasimahla ziyafumaneka ngobude obulinganiselweyo (≤1m) xa ziceliwe, kunye neesatifikethi ezineenkcukacha zezinto kunye neengxelo zohlalutyo lokungcola.
