Thermocouple Wire and Thermocouple Extension Wire

High Temperature Vitreous Silica Braided Thermocouple Wire SERIES 301 and 365 (32)
Both the SERIES 301 and 365 use vitreous silica yarn as the insulation on both the conductors and duplex. This yarn retains its flexibility after exposure to high temperatures.
The vitreous silica yarn’s greater purity performs better at high temperatures than other fibrous glass products. Testing has indicated that “contamination” will compromise this material’s upper use temperature. For this reason, our standard offering is supplied without color coding or impregnations. The 365 construction is a cost-effective, medium insulation build of the popular heavy duty 301 construction.
