High Temperature Cable Thermocouple Compensation Wire Type T Thermocouple Extension Wire

• Thermocouple Extension Wire

T-type thermocouple compensation wire is a special wire used to connect T-type thermocouples with temperature measuring instruments. It is mainly used to extend the cold end of the thermocouple to compensate for the measurement error caused by the change of the cold end temperature. It has excellent thermoelectric performance and stability, and can maintain the same thermoelectric electromotive force characteristics as T-type thermocouples within a certain temperature range (such as -60℃ to 260℃).
T-type compensation wire is usually made of copper-copper-nickel alloy material, and there are many options for insulation layer and sheath materials, such as polyvinyl chloride (PV), polyperfluoroethylene propylene (FEP) and soluble polytetrafluoroethylene (PFA) to meet the use requirements in different environments. Its common models include TX-G (general use), TX-H (general use), TX-GS (precision general use) and TX-HS (precision heat-resistant use).
This compensation wire is widely used in the automated temperature measurement system of petroleum, chemical, metallurgy, electric power and other industries, which can effectively improve the temperature measurement accuracy and ensure the stability and reliability of the measurement system.

Copper-copper-nickel thermocouple (T-type thermocouple), also known as copper-constantan thermocouple, is an optimal low-cost metal thermocouple for measuring low temperatures. Its positive electrode (TP) is pure copper, and its negative electrode (TN) is a copper-nickel alloy, often called constantan. It is compatible with constantan EN of nickel-chromium-constantan, but not with constantan JN of iron-constantan, although they are both called constantan.
The measurement temperature range of copper-copper-nickel thermocouple is -200~350°C.

• Feature

  ---

Material and structure: T-type compensation wire is usually made of copper (positive electrode) and copper-nickel alloy (negative electrode), and the insulation layer is red (positive electrode) and white (negative electrode).
Temperature range: The operating temperature range of the compensation wire is -40℃ to 70℃ or 105℃ for ordinary grade, and -65℃ to 200℃ or 260℃ for heat-resistant grade.
Accuracy level: It is divided into ordinary grade and precision grade, and the precision grade has higher measurement accuracy.
Anti-interference ability: Some compensation wires adopt shielding design, which can effectively reduce electromagnetic interference.
