Inkcazelo emfutshane:

Uhlobo lwe-B lwe-thermocouple wire luhlobo lwenzwa yobushushu eyinxalenye yentsapho ye-thermocouple, eyaziwa ngokuchaneka kwayo okuphezulu kunye nokuzinza. Yenziwe ngeengcingo ezimbini ezahlukeneyo zetsimbi ezidityaniswe kunye kwelinye icala, ngokuqhelekileyo zenziwe nge-platinum-rhodium alloys. Kwimeko ye-thermocouples yoHlobo lwe-B, olunye ucingo lwenziwe nge-70% yeplatinum kunye ne-30% ye-rhodium (Pt70Rh30), ngelixa olunye ucingo lwenziwe nge-94% yeplatinum kunye ne-6% ye-rhodium (Pt94Rh6).

Ii-thermocouples zodidi lwe-B ziyilelwe ukulinganisa amaqondo obushushu aphezulu, ukusuka ku-0°C ukuya kwi-1820°C (32°F ukuya kuma-3308°F). Zidla ngokusetyenziswa kwizicelo ezinje ngeziko lemizi-mveliso, iikhilni, kunye novavanyo lwaselabhoratri olunobushushu obuphezulu. Ngenxa yokudityaniswa okuchanekileyo kwezinto ezisetyenzisiweyo, uhlobo lwe-thermocouples lwe-B lunika uzinzo olugqwesileyo kunye nokuchaneka, ngakumbi kumaqondo obushushu aphezulu.

Ezi thermocouples zikhethwa kwiimeko apho ukuchaneka okuphezulu kakhulu kuyadingeka, nangona zibiza kakhulu kunezinye iintlobo ze-thermocouples. Ukuchaneka kwabo kunye nokuzinza kwabo kubenza bafanelekele izicelo ezifunwayo kumashishini afana ne-aerospace, i-automotive, kunye ne-metallurgy.
