I-Tankii Khiqiza uhlobo lwekhebula le-thermocouple B PtRh30-PtRh6
Incazelo Yomkhiqizo
Thayipha i-Thermocouple Wire
Uhlolojikelele Lomkhiqizo
Intambo ye-thermocouple yohlobo lwe-B iyi-thermocouple yensimbi eyigugu esebenza kahle kakhulu ehlanganisa ama-alloy amabili e-platinum-rhodium: umlenze oqondile ona-30% we-rhodium no-70% weplatinum, nomlenze ongemuhle one-rhodium engu-6% kanye ne-platinum engu-94%. Idizayinelwe izindawo ezisezingeni eliphezulu kakhulu zokushisa, ikwazi ukumelana nokushisa kakhulu phakathi kwama-thermocouples ensimbi ayigugu, ihamba phambili ekuzinzeni nasekumelaneni ne-oxidation emazingeni okushisa angaphezu kuka-1500°C. Ukwakheka kwayo okuhlukile kwe-dual-platinum-rhodium kunciphisa ukukhukhuleka okubangelwa ukuhwamuka kweplatinamu, kuyenze ibe ilungele ukukalwa kwezinga lokushisa eliphezulu lesikhathi eside.
Ukuqokwa Okujwayelekile
- Uhlobo lwe-Thermocouple: Uhlobo lwe-B (Platinum-Rhodium 30-Platinum-Rhodium 6)
- Izinga le-IEC: IEC 60584-1
- Izinga le-ASTM: ASTM E230
- Ukubhala Umbala: Umlenze omuhle - ompunga; Umlenze ongemuhle - omhlophe (nge-IEC 60751)
Izici Eziyinhloko
- Ukumelana Nokushisa Okuphakeme Kakhulu: Ukushisa okusebenzayo kwesikhathi eside kufika ku-1600 ° C; ukusetshenziswa kwesikhashana kufika ku-1800°C
- I-EMF Ephansi Emazingeni Okushisa Aphansi: Okukhiphayo okuncane kwe-thermoelectric ngaphansi kuka-50°C, kunciphisa umthelela wephutha lendawo ebandayo
- I-Superior High-Temp Stability: ≤0.1% ukukhukhuleka ngemva kwamahora angu-1000 ku-1600°C
- Ukumelana Ne-oxidation: Ukusebenza kahle kakhulu emimoyeni ene-oxidizing; ukumelana nokuhwamuka kweplatinamu
- Amandla Emishini: Igcina i-ductility emazingeni okushisa aphezulu, afanele izindawo zezimboni ezinokhahlo

Izicelo Ezijwayelekile
- Izithando zokushisa ezishisa kakhulu ezishisayo (izinto ze-ceramic kanye ne-refractory)
- Ukuncibilika kwensimbi (i-superalloy kanye nokukhiqizwa kwensimbi okukhethekile)
- Ukukhiqiza ingilazi (ingilazi eyakha amafurnace)
- Ukuhlolwa kwe-Aerospace propulsion (amabhomu enjini yerokhethi)
- Imboni yeNyukliya (ukuqapha izinga lokushisa eliphezulu kwe-reactor)
Sihlinzeka ngezinhlobo ze-thermocouple zohlobo B ezinamashubhu okuvikela e-ceramic nezixhumi ezishisa kakhulu. Ngenxa yenani lempahla ephezulu, ubude besampula bukhawulelwe ku-0.5-1m uma ucelwa, buphelezelwa izitifiketi zempahla egcwele kanye nemibiko yokuhlaziya ukungcola. Ukucushwa okungokwezifiso kwezindawo ezithile zesithando somlilo kuyatholakala.
