Karma Wire kwa Precision Resistors(0.02mm, 0.03mm, 0.04mm)

1. Chigawo cha Karma

Karma alloy amapangidwa ndi mkuwa, faifi tambala, Aluminiyamu ndi Iron monga zigawo zikuluzikulu. The resistivity ndi 2 ~ 3 nthawi zambiri kuposa MENTONG. Imakhala ndi kutentha kocheperako (TCR), kutsika kwamafuta a EMF motsutsana ndi mkuwa, kukana kwanthawi yayitali komanso anti-oxidation yamphamvu. Kutentha kwake kogwira ntchito ndikokulirapo kuposa MENTONG (-60 ~ 300ºC). Ndikoyenera kupanga zinthu zokanira bwino kwambiri komanso zovuta.

2. Kukula kwa Karma

Waya: 0.01mm-10mm
Riboni: 0.05 * 0.2mm-2.0 * 6.0mm
Mzere: 0.5 * 5.0mm-5.0 * 250mm
3.Karma Katundu

4. Makhalidwe apadera a Karma resistance waya

1) Kuyambira ndi Nickel Chromium waya wotentha wamagetsi Kalasi 1, tidasintha zina mwa Ni ndi
Al ndi zinthu zina, motero adapeza zida zokanira zolondola ndikuwongolera
kukana kutentha kokwanira ndi kutentha kwa electromotive mphamvu motsutsana ndi mkuwa.
Ndi kuwonjezera kwa Al, tachita bwino kupanga voliyumu resistivity 1.2 nthawi zazikulu
kuposa Nickel Chromium mawaya otentha amagetsi a Gulu 1 ndi mphamvu zamakokedwe kuwirikiza ka 1.3.

2) Kutentha kwachiwiri β wa waya wa Karmalloy KMW ndi kochepa kwambiri, - 0.03 × 10-6 / K2,

ndi kukana kutentha pamapindikira kumakhala pafupifupi mzere wowongoka mkati mwa lonse
kutentha osiyanasiyana.

Chifukwa chake, kutentha kwapakati kumayikidwa kukhala pafupifupi kutentha kwapakati
23 ~ 53 °C, koma 1 × 10-6/K, pafupifupi kutentha kokwanira pakati pa 0 ~ 100 °C, nawonso akhoza
kutengera kutentha kwa coefficient.

3) Mphamvu yamagetsi yolimbana ndi mkuwa pakati pa 1 ~ 100 ° C ndi yaying'ono, pansipa + 2 μV/K, ndi

zimasonyeza kukhazikika kwabwino kwambiri kwa zaka zambiri.

4) Ngati izi zikuyenera kugwiritsidwa ntchito ngati zida zokanira molondola, chithandizo cha kutentha chotsika ndi
zofunika kuthetsa kupotoza processing monga nkhani ya Manganin waya CMW.
