J type thermocouple
Description of J type thermocouple :
J type thermocouple), also known as iron - constantan thermocouple, is also a kind of cheap cheap metal thermocouple. Its positive electrode (JP) in the name of the chemical composition of pure iron, copper and nickel alloy anode (Jacqueline Nottingham), are often vaguely call constantan, its nominal chemical composition of: 55% copper and 45% nickel as well as small amounts of very important manganese, cobalt, iron and other elements, although it's called constantan, but different from that of nickel and chromium - constantan and copper-constantan constantan, so can't use EN and TN to replace. Iron - constantan thermocouple measuring temperature area is - 200 ~ 200 ℃, but usually use temperature range of 0 ~ 750 ℃.
J type thermocouple has advantages of good linearity, thermoelectric emfs, high sensitivity, good stability and uniformity, the advantages of cheap, widely used by users. J type thermocouple can be used in the vacuum, oxidation, reduction and inert atmosphere, but iron anode oxidation at high temperature quickly, so the temperature is restricted, cannot be directly without reserve for curing atmosphere at high temperature.
