Product Description
First Class TC wire 0.4mm Chrmel constantan thermocouple wire (type E )
Thermocouple wire is a type of electrical wire that is used to measure temperature.
It is made up of two different metals that are joined together at one end.
When the joined end is exposed to heat, a voltage is produced that is proportional to the temperature difference between the joined end and the other end of the wire.
This voltage can be measured and used to determine the temperature of the object being measured.
Thermocouple wire is commonly used in industrial applications where accurate temperature measurement is critical.
NiCr- CuNi thermocouple (type E) is also named NiCr-Constantan thermocouple.
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.
