4. Likarolo tse ikhethang tsa mohala oa ho hanyetsa Karma
1) Ho qala ka Nickel Chromium terata ea mocheso oa motlakase oa Sehlopha sa 1, re nkile sebaka sa Ni ka
Al le likarolo tse ling, 'me kahoo e fihletsoe ka mokhoa o nepahetseng oa ho hanyetsa thepa e ntlafalitsoeng
ho hanyetsa mocheso coefficient le mocheso electromotive matla khahlanong le koporo.
Ka tlatsetso ea Al, re atlehile ho etsa hore molumo oa resistivity 1.2 o be moholo
ho feta Nickel Chromium terata ea mocheso ea motlakase ea Sehlopha sa 1 le matla a thata ka makhetlo a 1.3.
2) Mocheso oa bobeli oa mocheso β oa Karmalloy terata KMW o nyane haholo, - 0.03 × 10-6/ K2, 'me sekhahla sa mocheso oa ho hanyetsa se fetoha mohala o otlolohileng ka har'a bophara bo pharaletseng.
mocheso oa mocheso.
Ka hona, mocheso oa mocheso o behiloe ho ba karolelano ea mocheso oa mocheso pakeng tsa
23 ~ 53 °C, empa 1 × 10-6/K, karolelano ea mocheso pakeng tsa 0 ~ 100 °C, le eona e ka
ho amoheloa bakeng sa coefficient ea mocheso.
3) Matla a motlakase khahlano le koporo lipakeng tsa 1 ~ 100 °C le ona a nyane, ka tlase ho + 2 μV/K, le
e bontša botsitso bo babatsehang nakong ea lilemo tse ngata.
4) Haeba sena se tla sebelisoa e le thepa ea ho hanyetsa ka mokhoa o nepahetseng, phekolo ea mocheso o tlaase oa mocheso ke
e hlokehang ho felisa ho khopama ho sebetsa joalo ka ha ho le joalo ka terata ea Manganin CMW.
