K-type thermocouples are the most widely used temperature sensors in industrial applications. Our shielded type k thermocouple wire is specifically designed for K-type measurement systems. The positive conductor is nickel-chromium, and the negative conductor is nickel-silicon. This alloy combination is matched to K-type thermocouple characteristics, ensuring consistent thermoelectric performance across the full temperature range. This helps reduce system deviation and minimizes cold junction measurement errors, improving overall temperature accuracy.
Strong Shielding Against Interference
Shielding is a critical feature of this product. We offer two shielding options: aluminum foil and tinned copper braid. Aluminum foil shielding is highly effective against high-frequency electromagnetic interference, making it suitable for environments with VFDs and switching equipment. Tinned copper braid shielding provides mechanical robustness and achieves coverage above 85%, offering strong protection across a wide range of EMI frequencies.
For high-noise environments, a dual-shield configuration combining both foil and braid shielding is also available. This provides enhanced protection for sensitive temperature measurement signals in complex industrial conditions.
The jacket materials are designed for different operating environments. Flame-retardant PVC is suitable for general industrial use, with a temperature range of -20°C to 105°C. Fluoroplastic insulation is available for high-temperature and chemically aggressive environments, with resistance up to 200°C.
We have extensive experience in manufacturing K-type thermocouple and compensating wires, with strict control over alloy composition and production processes. Our products comply with IEC 60584-3 standards and are CE and RoHS certified.
Each production batch is tested for thermoelectric performance and insulation strength to ensure consistent quality and measurement accuracy. Common shielded K-type models such as KX and KC are available from stock. Special versions including flame-retardant, high-temperature, and intrinsically safe types are available upon request.
