This 20 AWG, 100ft roll is specifically engineered for optimal signal integrity, critical for applications ranging from industrial process control to laboratory research.

Understanding Thermocouple Extension Wire: Thermocouple extension wire plays a vital role in accurately transmitting the millivolt signal generated by a thermocouple sensor to the readout or control device. Maintaining signal integrity over distance is paramount for precise temperature readings. To achieve this, the extension wire's material composition must precisely match the positive and negative legs of the thermocouple type being used (e.g., Type K, J, T, E, N). This adherence to material compatibility prevents unwanted thermoelectric errors, ensuring the highest degree of accuracy in your measurements.

When to Use Copper Wire: In scenarios where a transmitter is integrated directly into the thermocouple sensor assembly, a scalable (e.g., 4 to 20 mA) signal is often generated. In such cases, standard copper instrumentation wire is typically used to carry this amplified signal back to the process control equipment. This is because the signal is no longer a raw millivolt output requiring specific thermocouple alloy compensation.

RTD Sensor Wiring: Resistance Temperature Detector (RTD) sensors operate on a different principle, measuring changes in electrical resistance with temperature. Consequently, RTD sensors utilize ordinary copper instrumentation cable to transmit their resistance signal to recording, readout, or control devices. Similar to thermocouples, if a transmitter is present within the RTD sensor assembly, copper wire is employed for the scalable (4 to 20 mA) signal transmission.
