  E Type Thermocouple Wire

NiCr- CuNi(Constantan) thermocouple (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, 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. It also has 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 sulphur gases.

 Factory of E type thermocouple   

Senphus Electrical Material Co., Ltd was founded in 2003, which is a leading manufacturer of heating resistance alloy material in China. The main process equipments have reached the international level. The company worked out a complete, mature production process of heating alloy from smelting, steel rolling, drawing, heating treatment to the finished product, and established chemical analysis dept, physical testing dept, ect.

The company produces hundreds of types products with the "REOU" band, comprising over a thousand specifications under seven main categories. Copper-based low resistance heating alloys (CuNi1-CuNi44); precision resistance alloys (Karma, manganin and constantan); high resistance heating alloys (nickel-chromium alloy wire); thermocouple alloys (K, N, T, J type); thermocouple extension wire alloys; PTC thermistor resistance alloy and specialty wire (pure nickel wire and corrosion-resistant (Monel) alloy) with wire, strip, ribbon, bar, foil, sheet, stranded. The products have stable physical performance, high surface loading, oxidation resistance, high electrical resistivity and stable temperature coefficient of resistance, ect., so they are widely used in malitary project, aerospace, household appliances, heating wire, mechanical, electrical plant, temperature instruments, and many other field s. Due to the annual output of 1500 tons, and the KANTHAL level or more better quality, we become the designated supplier of many world-renowned brand.
