Khiqiza i-Nickel Karma/EvanohmI-Precision Alloy Wirengomshini we-Defrost
1. Evanohm ingxubevange
I-Evanohm alloy yenziwe ngethusi, i-nickel, i-Aluminium ne-Iron njengezingxenye eziyinhloko. I-resistivity iphakeme izikhathi ezingu-2 ~ 3 kune-MENTONG. Ine-coefficient ephansi yokushisa yokumelana (i-TCR), i-EMF eshisayo ephansi uma iqhathaniswa nethusi, ukuhlala unomphela okuhle kokumelana isikhathi eside kanye ne-anti-oxidation eqinile. Izinga layo lokushisa elisebenzayo libanzi kune-MENTONG (-60~300ºC). Ilungele ukwenza izakhi zokumelana nokunemba okuhle kanye nobunzima.
2. Usayizi we-Evanohm
Intambo: 0.018mm-10mm
Iribhoni: 0.05*0.2mm-2.0*6.0mm
Uhlaka: 0.5 * 5.0mm-5.0 * 250mm
Ububanzi: 10-100 mm

4. Izici ezihlukile ze-Evanohm resistance wire
1) Ukuqala nge-Nickel Chromium yentambo yokushisa kagesi ye-Class 1, sishintshe enye ye-Ni
I-Al nezinye izakhi, futhi ngaleyo ndlela kuzuzwe okunembayo ukumelana nokusetshenziswa okuthuthukisiwe
ukumelana nokushisa kwe-coefficient kanye nokushisa kwe-electromotive force ngokumelene nethusi.
Ngokungezwa kwe-Al, siphumelele ukwenza ivolumu yokuphikiswa izikhathi eziphindwe ka-1.2
kunentambo yokushisa kagesi ye-Nickel Chromium Ikilasi 1 namandla aqinile ngokuphindwe izikhathi ezingu-1.3.
2) I-coefficient yesibili yokushisa engu-β ye-Karmalloy wire KMW incane kakhulu, - 0.03 × 10-6/ K2,
futhi ijika lokushisa lokumelana liphenduka cishe umugqa oqondile phakathi kobubanzi
izinga lokushisa.
Ngakho-ke, i-coefficient yezinga lokushisa isethwe ukuthi ibe yisilinganiso se-temperature coefficient phakathi
23 ~ 53 °C, kodwa 1 × 10-6/K, isilinganiso sesilinganiso sokushisa esiphakathi kuka-0 ~ 100 °C, singase futhi
yamukelwe i-coefficient yezinga lokushisa.
3) Amandla kagesi ngokumelene nethusi phakathi kuka-1 ~ 100 °C nawo mancane, ngaphansi kuka + 2 μV/K, futhi
ikhombisa ukuzinza okuhle kakhulu phakathi neminyaka eminingi.
4) Uma lokhu kuzosetshenziswa njengento yokumelana nokunemba, ukwelashwa kokushisa okuphansi
okudingekayo ukuze kuqedwe ukuhlanekezelwa kokucubungula njengoba kwenzeka ku-Manganin wire CMW.
