0.08mm Enamelled NICR alloy NiCr20AlSi/nichrome Karma Resistance Uaea fa'avevela fa'avevela.

Fa'amatalaga Puupuu:

ua fa'aaoga lautele ia uaea tetee enamled mo resistors tulaga, taavale
vaega, fe'avea'i tetee, ma isi. fa'aogaina le fa'aogaina o le insulation e sili ona fetaui lelei mo nei fa'aoga, fa'aaoga lelei atoatoa o uiga fa'apitoa o le fa'apipi'iina o le enamel.

E le gata i lea, o le a matou faʻatinoina le faʻapipiʻiina o le faʻapipiʻiina o le enamel o le uaea uʻamea taua e pei o le siliva ma le uaea platinum i luga o le faʻatonuga. Fa'amolemole fa'aaoga lenei gaosiga-i-oka.

    4. Tulaga iloga o le uaea tetee a Karma

    1) Amata i le Nickel Chromium uaea vevela eletise Vasega 1, matou suia nisi o le Ni ma
    Al ma isi elemene, ma faʻapea ona ausia se mea faʻamaonia saʻo ma faʻaleleia
    tete'e o le vevela coefficient ma le vevela eletise malosi e faasaga i le kopa.
    Faatasi ai ma le faʻaopoopoga o Al, ua matou manuia i le faia o le voluma resistivity 1.2 taimi sili atu
    nai lo Nickel Chromium uaea vevela eletise Vasega 1 ma le malosi tensile 1.3 taimi sili atu.

    2) O le lua vevela coefficient β o Karmalloy uaea KMW e laʻititi lava, - 0.03 × 10-6 / K2,

    ma o le pupuni o le vevela e foliga mai e toetoe lava o se laina sao i totonu o le lautele
    fua vevela.

    O le mea lea, o le fua fa'atatau o le vevela o lo'o fa'atulagaina e avea ma fua fa'atatau o le vevela i le va
    23 ~ 53 °C, ae 1 × 10-6/K, o le averesi o le vevela coefficient i le va o 0 ~ 100 °C, e mafai foi
    e fa'aaogaina mo le fa'atatau o le vevela.

    3) Electromotive malosi faasaga i kopa i le va o le 1 ~ 100 °C e laʻititi foi, lalo + 2 μV / K, ma

    fa'aalia le mautu lelei mo se vaitaimi o le tele o tausaga.

    4) Afai e faʻaaogaina lenei mea e avea o se mea e teteʻe ai, o le vevela vevela vevela
    manaʻomia e faʻaumatia faʻalavelave faʻagasologa e pei lava o le tulaga o le Manganin wire CMW.
