- Thermocouple Extension Wire
E-type thermocouple compensation wire is a high-performance
connecting cable designed for E-type thermocouples. It is mainly
used to extend the measurement loop of the thermocouple and
compensate for the error caused by the change of the cold end
temperature. It has excellent thermoelectric properties, high
temperature resistance, corrosion resistance and good insulation.
It usually uses a fluoroplastic insulation layer to ensure the
stability and accuracy of signal transmission. It is widely used in
industrial fields such as petroleum, chemical, metallurgy and
electric power industries, and can effectively improve the accuracy
and reliability of the temperature measurement system. When using
it, pay attention to model matching, correct connection and avoid
environmental interference to ensure the accuracy of the
measurement.
Nickel-chromium-copper-nickel thermocouple (E-type thermocouple),
also known as nickel-chromium-constantan thermocouple, is also a
cheap metal thermocouple. Its positive electrode (EP) is
nickel-chromium 10 alloy, with the same chemical composition as KP,
and its negative electrode (EN) is copper-nickel alloy, with a
nominal chemical composition of 55% copper, 45% nickel, and a small
amount of cobalt, manganese, iron, etc. The operating temperature
of this thermocouple is -200~900°C.

- High sensitivity: E-type thermocouples have high thermoelectric
potential output, so their compensation wires can provide more
accurate measurements.
- High temperature and corrosion resistance: The compensation wires
are usually made of high temperature and corrosion resistant
insulation materials, suitable for complex industrial environments.
- Strong anti-interference ability: Some compensation wires are
shielded, which can effectively reduce electromagnetic
interference.
- Usage temperature range: generally -25℃ to 200℃, suitable for a
variety of environments.
- Model matching: E-type thermocouples must use E-type compensation
wires and cannot be mixed with other types.
- Correct polarity connection: The positive and negative poles of the
compensation wire must be correctly connected to the positive and
negative poles of the thermocouple and the measuring instrument.
- Environmental adaptability: Select the appropriate insulation
sheath material according to the use environment, such as
polytetrafluoroethylene for high temperature environments.
- Regular inspection and maintenance: The compensation wire may age
after long-term use, and regular inspection is required to ensure
measurement accuracy.
