Type J Thermocouple Extension Wire - Items tagged as "20-gage-thermocouple-wire-with-pfa-insulation"

Type J Thermocouple Extension Wire is designed to extend the thermocouple signal from J Type Thermocouple probes or sensors to controllers, dataloggers and electronic displays.

• Extension Grade thermocouple wire is not as accurate as thermocouple wire and is not recommended to be utilized to create a 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 J extension wire is white positive, red negative and typically has a Black outside jacket. 
  • Thermocouple grade wire with a Brown jacket can be subsituted for Extension Grade Wire
