Thermocouple Extension Wire is a cable designed to extend thermocouple signals and is suitable for a variety of thermocouple types, including Type K, Type N, Type E, Type J, Type T, Type B, Type R, and Type S. It plays a vital role in the field of temperature measurement and control.
The main purpose of Thermocouple Extension Wire is to transmit the thermocouple signal from the measurement point to the instrument or control system for accurate temperature measurement and monitoring. This cable uses thermocouple wires made of two different metal materials to determine the temperature value by measuring the temperature difference between the two junctions. Its special design and material selection ensure good linear characteristics and stability, and can accurately capture and transmit weak thermocouple voltage signals.
Thermocouple Extension Wire has excellent anti-interference capabilities and can effectively resist the effects of electromagnetic interference, noise and temperature changes on signals. This enables it to stably transmit reliable temperature data in industrial environments, ensuring the accuracy and reliability of temperature measurement.
