Product Description

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, JN are all called constantan, EN and TN don 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 type E thermocouple is -200-900°C

Type E thermocouple has the largest EMF output and highest sensitivity, so it is ideal for measuring small temperature change

With good stability in the low temperature range up to 300°C, and good property of anti-corrosion in humidity atmosphere

It is recommended for oxidizing or inert atmospheres, but cannot be used directly in reducing atmosphere and atmosphere with sulfur gases

Thermocouples wire (class 1, and 2):

Type B (Pt-30Rh Vs Pt-6Rh) thermocouples wire

Type R (Pt-13Rh Vs Pt) thermocouples wire

Type S (Pt-10Rh Vs Pt) thermocouples wire

Type K (Ni-10Cr Vs Ni-3Si) thermocouples wire

Type E (Ni-10Cr Vs Cu-45Ni) thermocouples wire

Type T (Cu Vs Cu-45Ni) thermocouples wire

Type J (Fe Vs Cu-45Ni) thermocouples wire
