Product Description
E type thermocouple wire IEC584 class one 0.1~8mm
Type E thermocouple is a cheap metal thermocouple.
The positive electrode (EP) is nickel chromium 10 alloy with the same chemical composition as KP.
The negative electrode (EN) is copper nickel alloy.
The nominal chemical composition is 55% copper, 45% nickel and a small amount of manganese, cobalt, iron and other elements.
The working temperature of the thermocouple is - 200~900 ºC.
What is a Thermocouple?
A Thermocouple is a sensor used to measure temperature.
Thermocouples consist of two wire legs made from different metals.
The wires legs are welded together at one end, creating a junction.
This junction is where the temperature is measured.
When the junction experiences a change in temperature, a voltage is created.
The voltage can then be interpreted using thermocouple reference tables to calculate the temperature.
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.
