Chromel C e nang le Resistivity e Phahameng bakeng sa Lionto tsa Toaster le Lihitara tsa Polokelo

Tlhaloso e Khutšoanyane:

Chromel C e sebedisetswa thepa ya motlakase ya ho futhumatsa disebedisweng tsa lapeng. Ditshebediso tse tlwaelehileng ke dielemente tsa tšepe tse nang le sekwahelo sa shubula tse sebediswang, mohlala, dipoleiting tse chesang, di-grill, diontong tsa toaster le di-heater tsa polokelo. Di-alloy Chromel C e boetse e sebedisetswa di-coil tse leketlileng di-heater tsa moya di-dryer tsa diaparo, di-heater tsa fene, di-dryer tsa letsoho.

    Li-tag tsa Sehlahisoa

    Chromel C ke motsoako oa austenitic nickel-chromium (motsoako oa NiCr) o sebelisetsoang ho sebelisoa mochesong o fihlang ho 1150°C. Motsoako o nepahetseng oa chromium-nickel Chromel C e khetholloa ka ho hanyetsa ho phahameng, ho hanyetsa hantle ha oxidation le botsitso bo botle haholo ba sebopeho. E na le ho dutla ho hoholo kamora ts'ebeliso le ho tjheseletsa ho hoholo.

    Kopo:

    • li-resistor tse hanyetsang haholo le tsa potentiometer.
    • lintho tse futhumatsang tsa motlakase (tšebeliso ea lapeng le indastering).
    • lionto tsa indasteri tse fihlang ho 1100°C.
