Inkcazo emfutshane:

Intambo ye-thermocouple yohlobo B luhlobo lwe-sensor yobushushu eyinxalenye yosapho lwe-thermocouple, eyaziwa ngokuchaneka kwayo kubushushu obuphezulu kunye nokuzinza. Yenziwe ngeentambo ezimbini ezahlukeneyo zesinyithi ezidityaniswe kwelinye icala, eziqhele ukwenziwa ngee-alloys zeplatinum-rhodium. Kwimeko yee-thermocouples zohlobo B, intambo enye yenziwe nge-70% yeplatinum kunye ne-30% ye-rhodium (Pt70Rh30), ngelixa enye intambo yenziwe nge-94% yeplatinum kunye ne-6% ye-rhodium (Pt94Rh6).

Ii-thermocouples zohlobo B zenzelwe ukulinganisa amaqondo obushushu aphezulu, ukusuka kwi-0°C ukuya kwi-1820°C (32°F ukuya kwi-3308°F). Zisetyenziswa kakhulu kwizicelo ezifana nee-ovens zoshishino, ii-ovens, kunye novavanyo lwelabhoratri lobushushu obuphezulu. Ngenxa yokudibanisa ngokuchanekileyo kwezinto ezisetyenzisiweyo, ii-thermocouples zohlobo B zibonelela ngozinzo olugqwesileyo kunye nokuchaneka, ngakumbi kumaqondo obushushu aphezulu.

Ezi thermocouples zikhethwa kwiimeko apho kufuneka ukuchaneka okuphezulu kakhulu, nangona zibiza kakhulu kunezinye iintlobo zethermocouples. Ukuchaneka kwazo kunye nokuzinza kwazo kuzenza zilungele ukusetyenziswa ngokungxamisekileyo kumashishini afana neenqwelo-moya, iimoto, kunye nesinyithi.
