NiCr-NiSi (Type K) thermocouple finds the widest use in all basemetal thermocouple, at temperature above 500 C. The main chemical composition of positive leg Nicr (KP) are Ni=90% and Cr-10%; negative leg NiSi (KN) are Ni=97% and Cr=3%. The operating temperature range is -200 to 1100 C.
Type K thermocouple has strong resistance to oxidation than other base metal thermocouples. It has high EMP against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost. It is recommended for oxidizing or inter atmostpheres.
Fe-CuNi thermocouple (Type J) is also named Fe-Constantan thermocouple. The positive leg Fe(JP) is made by pure Iron, and the main chemical composition of negative leg Constantan (JN) is Cu=55% and Ni=45%. Although they are all called Constantan, JN does not give the same EMF output curve as EN & TN, it cannot be instead by other Constantan.
The Operating temperature range of type J thermocouple is -210 to 1200 C, but it is usually used in the temperature range 0 to 750 C due to embrittlement of Iron.
Type J thermocouple has good resistance to oxidation and high EMF output against Platinum 67, with good temperature accuracy, sensitivity and stability. It is recommended for vacuum, oxidizing, reducing or inter atmospheres, but it cannot be used in sulphurous atmosphere above 500 C.
