Tlhaloso e Khutšoanyane:

Mofuta oa B oa mohala oa thermocouple ke mofuta oa sensor ea mocheso eo e leng karolo ea lelapa la thermocouple, e tsejoang ka ho nepahala ha mocheso o phahameng le botsitso. E entsoe ka lithapo tse peli tse fapaneng tsa tšepe tse kopantsoeng ka lehlakoreng le leng, hangata li entsoe ka li-alloys tsa platinum-rhodium. Tabeng ea mofuta oa B thermocouples, terata e le 'ngoe e entsoe ka 70% platinum le 30% rhodium (Pt70Rh30), ha mohala o mong o entsoe ka 94% platinum le 6% rhodium (Pt94Rh6).

Mefuta ea B ea thermocouple e etselitsoe ho lekanya mocheso o phahameng, ho tloha ho 0°C ho ea ho 1820°C (32°F ho isa 3308°F). Hangata li sebelisoa lits'ebetsong tse kang libopi tsa indasteri, libotlolo, le liteko tsa laboratori tsa mocheso o phahameng. Ka lebaka la motsoako o nepahetseng oa lisebelisoa tse sebelisoang, li-thermocouples tsa Mofuta oa B li fana ka botsitso le ho nepahala, haholo-holo mocheso o phahameng.

Li-thermocouples tsena li khethoa maemong ao ho hlokahalang ho nepahala ho phahameng haholo, le hoja li theko e boima ho feta mefuta e meng ea thermocouples. Ho nepahala ha tsona le botsitso ba tsona li li etsa hore li tšoanelehe bakeng sa lits'ebetso tse hlokang liindasteri tse kang sefofane, likoloi le metallurgy.
