Chiwanikwa 290/C17200 waya ye alloy ye nickel-copper ye potentiometers/shunts

Chigadzirwa cheManganin chinonyatsoratidza kuti tembiricha yakaderera iri pakati pe20 ne50 °C ine chimiro cheR(T) curve, kugadzikana kwakanyanya kwesimba remagetsi kwenguva refu, EMF yakaderera zvakanyanya kana ichienzaniswa nemhangura uye hunhu hwakanaka hwekushanda.
Zvisinei, mafuta akawanda anorema munzvimbo isina oxidizing anogona kushandiswa. Kana ikashandiswa kune ma resistors akanyatsonaka ane zvinodiwa zvepamusoro, ma resistors anofanira kugadzikiswa nokungwarira uye tembiricha yekushandisa haifanirwe kudarika 60°C. Kupfuura tembiricha yepamusoro yekushanda mumhepo kunogona kukonzera resistance drift inogadzirwa ne oxidizing processes. Saka, kugadzikana kwenguva refu kunogona kukanganiswa zvakaipa. Nekuda kweizvozvo, resistivity pamwe chete netembiricha coefficient ye electric resistance zvinogona kuchinja zvishoma. Inoshandiswawo sechinhu chinotsiva chesirivha chinosungirirwa pasimbi yakaoma.

Magadzirirwo
waya yemanganin/CuMn12Ni2 Waya inoshandiswa mu rheostats, resistors, shunt etc waya yemanganin 0.08mm kusvika 10mm 6J13, 6J12, 6J11 6J8
Waya yeManganin (kapu-)waya yemanganese() izita rekutengeserana remhando ye alloy inowanzo kuve 86% mhangura, 12% manganese, uye 2-5% nickel.
Waya yeManganin nefoil zvinoshandiswa mukugadzira resistor, kunyanya ammeter shunts, nekuda kwekuti haina resistance yakakwana uye inogara kwenguva refu.

Kushandiswa kweManganin

Foil yeManganin newaya zvinoshandiswa mukugadzira resistor, kunyanya ammeter shunt, nekuda kwekusakwana kwayo kwekupisa uye kugadzikana kwenguva refu.
Chishandiso chekupisa chine simba rekudzivirira kupisa chakagadzirwa nemhangura chinoshandiswa zvakanyanya mukudzikisa magetsi emagetsi ane simba remagetsi, thermal overload relay, nezvimwe zvigadzirwa zvemagetsi zvine simba remagetsi. Ndicho chimwe chezvinhu zvakakosha zvezvigadzirwa zvemagetsi zvine simba remagetsi. Zvinhu zvakagadzirwa nekambani yedu zvine hunhu hwekudzivirira kwakanaka uye kugadzikana kwakanyanya. Tinogona kupa marudzi ese ewaya dzakatenderera, dzakatsetseka uye dzakapfava.
