Compensating Cable

Compensating cables are special cables used with thermocouples to transmit signals from the measuring junction to the instrument. Their thermoelectric properties match those of the thermocouple, compensating for the effect of ambient temperature on measurement accuracy. They are classified into different types corresponding to thermocouple categories (such as Type K and Type J).
The materials are carefully selected: conductors are typically made of copper, copper-nickel alloys, or nickel-chromium alloys, while the insulation and sheaths use temperature-resistant materials such as fluoroplastics (FEP, PFA), cross-linked polyethylene (XLPE), or PTFE. These properties allow them to perform reliably in high-temperature industrial environments.
They are mainly used in industrial temperature measurement systems to maintain accurate readings.
