Incazelo emfushane:

Intambo ye-thermocouple yohlobo B uhlobo lwenzwa yokushisa eyingxenye yomndeni we-thermocouple, eyaziwa ngokunemba kwayo kokushisa okuphezulu kanye nokuqina. Yakhiwe ngezintambo ezimbili zensimbi ezahlukene ezihlanganiswe ndawonye ekugcineni, ngokuvamile ezenziwe ngama-alloy e-platinum-rhodium. Endabeni yama-thermocouple yohlobo B, intambo eyodwa yakhiwa yi-platinum engu-70% kanye ne-rhodium engu-30% (Pt70Rh30), kanti enye intambo yenziwe nge-platinum engu-94% kanye ne-rhodium engu-6% (Pt94Rh6).

Ama-thermocouple ohlobo B aklanyelwe ukukala amazinga okushisa aphezulu, asukela ku-0°C kuya ku-1820°C (32°F kuya ku-3308°F). Avame ukusetshenziswa ezisetshenziswayo njengezitofu zezimboni, ama-kiln, kanye nokuhlolwa kwelebhu okushisa okuphezulu. Ngenxa yokuhlanganiswa okunembile kwezinto ezisetshenziswayo, ama-thermocouple ohlobo B anikeza ukuzinza nokunemba okuhle kakhulu, ikakhulukazi emazingeni okushisa aphezulu.

Lawa ma-thermocouple ayathandwa ezimweni lapho kudingeka khona ukunemba okuphezulu kakhulu, yize ebiza kakhulu kunezinye izinhlobo zama-thermocouple. Ukunemba kwawo kanye nokuqina kwawo kuwenza afanelekele ukusetshenziswa okudingakalayo ezimbonini ezifana nezindiza, izimoto, kanye ne-metallurgy.
