What is the N type thermocouple?

What is the N type thermocouple? N type thermocouple is inexpensive metal thermocouple, thermocouple is also a kind of international standardization, is successfully developed by the Australian defence laboratory, in the early 70 s it restrained the K type thermocouple two defects: a K type thermocouple between 300 ~ 500 ℃ due to the lattice short-range order of nickel-chromium alloy thermoelectric emfs caused by unstable; At about 800 ℃ as nickel-chromium alloy preferential oxidation caused by unstable thermoelectric emfs.

N type thermocouple has advantages of good linearity, stability, and the average sex is good, high sensitivity, large thermoelectric emfs, strong anti-oxidation function, the price cheap, is not affected by short-range ordering strengths, such as its comprehensive function is better than that of K type thermocouple, is a way out of the thermocouple.
