NiCr-CuNi(constantan)thermocouple wire (Type-E)
NiCr- CuNi thermocouple (type E) is also named NiCr- Constantan thermocouple. The main chemical composition of positive leg NiCr (EP) is Ni: Cr=90:10; negative leg Constantan (EN) is Cu: Ni= 55%: 45%. Although EN, TN, and JN are all called Constantan, EN and TN do not give the same EMF output curve as JN. EN and TN are able to interchange, but they are not interchangeable with JN. The operating temperature range of the type E thermocouple is -200-900℃。
Type E thermocouple has the largest EMF output and highest sensitivity, so it is ideal for measuring small temperature changes. It also has good stability in the low temperature range up to 300 ℃, and good anti-corrosion properties in humidity atmosphere. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in reducing atmosphere and atmosphere with sulphur gases.
