The selective oxidation of Cr and Si elements in the Nickel-Chromium&#8217;s positive electrode in k-type thermocouple causes uneven composition of the alloy and thermoelectromotive force drift. Increases the content of Cr and Si in N-type thermocouple, Make the oxidation mode of nickel-chromium alloy change from internal oxidation to external oxidation, so that the oxidation reaction only takes place on the surface.<br \/>\n\u25cf Short-term thermal cycle stability is good under low temperature, and inhibits magnetic transformation.<br \/>\n\u25cf Strong resistance to nuclear radiation. N-type thermocouple remove Mn and Co, which are easy to decay in k-type thermocouple, and further strengthens the ability of neutron irradiation resistance.<br \/>\n\u25cf In the range of 400~1300\u2103, the linearity of n-type thermocouple is better than that of K-type thermocouple.<\/p>\n<p><strong>Disadvantages of N-type thermocouple:<\/strong><br \/>\n\u25cf Material of N-type thermocouple is harder than that of K-type thermocouple, it is more difficult to process.<br \/>\n\u25cf The price is relatively expensive. The thermal expansion coefficient of N-type thermocouple is 15% lower than that of stainless steel, so NiCrSi\/NiSi alloy should be used for the sheath of N-type armored thermocouple.
