Type K Thermocouple Extension Wire

Type K Thermocouple Extension Wire is designed to extend the thermocouple signal from the Thermocouple probe or sensor to Instrumentation.

• Extension Grade thermocouple wire should NOT be utilized to create the the temperature measurement, it is designed to accurately transfer the thermocouple signal. 
• Bare Wire Accuracy - extension grade thermocouple wire is typically tested to ensure accuracy in the temperature range of 32°F to 392°F (0°C to 200°C).
• Insulations on the extension wire are typically PVC (220°F or 105°C) FEP or PFA  fluoropolymers (400 to 500°F or 200 to 260°C) and Fiberglass Braid (900°F or 482°C)
  • Designs with wire insulation temperature ranges exceeding the typical bare wire accuracy range of 32°F to 392°F (0°C to 200°C) should be made from specially matched bare wire pairs to ensure accuracy in these higher temperature ranges.
• ANSI Color Code of Type K extension wire has a Yellow outside jacket, with a yellow positive wire and red negative.
  • Thermocouple grade wire with a Brown jacket can be subsituted for Extension Grade Wire
