Incazelo emfushane:

Intambo yohlobo B ye-thermocouple iwuhlobo lwenzwa yezinga lokushisa eyingxenye yomndeni we-thermocouple, eyaziwa ngokunemba kwayo kwezinga lokushisa eliphezulu nokuzinza. Yakhiwe ngezintambo ezimbili zensimbi ezihlukene ezihlanganiswe ndawonye ekugcineni, ngokuvamile ezenziwe ngama-alloys e-platinum-rhodium. Endabeni yama-thermocouples oHlobo lwe-B, ucingo olulodwa lwakhiwe ngeplatinum engu-70% kanye ne-rhodium engu-30% (Pt70Rh30), kanti olunye ucingo lwenziwe nge-platinum engu-94% kanye ne-rhodium engu-6% (Pt94Rh6).

Ama-thermocouples ohlobo B aklanyelwe ukukala izinga lokushisa eliphezulu, kusukela ku-0°C kuya ku-1820°C (32°F kuya ku-3308°F). Avame ukusetshenziswa ezinhlelweni ezifana neziko lezimboni, okhela, kanye nokuhlolwa kwaselabhorethri okunezinga lokushisa eliphezulu. Ngenxa yenhlanganisela enembile yezinto ezisetshenziswayo, ama-thermocouples ohlobo B anikeza ukuzinza nokunemba okuhle kakhulu, ikakhulukazi emazingeni okushisa aphezulu.

Lawa ma-thermocouples akhethwa ezimweni lapho kudingeka khona ukunemba okuphezulu kakhulu, nakuba ebiza kakhulu kunezinye izinhlobo ze-thermocouples. Ukunemba kwazo nokuzinza kwazo kuzenza zifanelekele izicelo ezifunwa kakhulu ezimbonini ezifana ne-aerospace, ezezimoto, nezensimbi.
