NiCr- CuNi thermocouple wire (type E) is also named NiCr-Constantan thermocouple wire. It has a stronger signal & higher accuracy than the Type K or Type J at moderate temperature ranges of 1,000F and lower. The type E is also more stable than the type K, which adds to its accuracy.
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 300ºC, 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.
Thermocouple ribbon wire, rods, strips can be supplied according to your request.
- Type E chemical composition:
Positive leg NiCr (EP) is Ni: Cr≈90:10; negative leg Constantan (EN) isCu: Ni≈ 55%: 45%
- Type E Accuracy (whichever is greater):
- Standard: +/- 1.7C or +/- 0.5%
- Special Limits of Error: +/- 1.0C or 0.4%
- Type E Temperature Range:
- Thermocouple grade wire, -454 to 1600F (-270 to 870C)
- Extension wire, 32 to 392F (0 to 200C)
Consideration for bare wire type E thermocouple applications:
- In oxiding or inert atmospheres the operating range is roughly –418F to 1,652F (–250C to 900C).
- Heating - Gas burners for ovens
- Cooling - Freezers
- Engine protection - Temperatures and surface temperatures
- High temperature control - Iron casting
