- 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.
