Description
The K-Type Armoured Thermocouple Extension Cable is engineered to provide reliable thermocouple signal transmission in industrial environments where standard cables are vulnerable to mechanical damage. Designed for extending the millivolt signal from K-Type (Chromel-Alumel) thermocouples to temperature controllers, PLCs, DCS systems, recorders, and monitoring equipment, the cable incorporates a stainless steel braided or interlocked armour that protects against crushing, abrasion, impact, vibration, and rodent damage. This robust construction makes it an ideal choice for exposed cable routes, outdoor installations, underground conduits, and heavy industrial applications where long-term durability is essential.
Manufactured with Chromel-Alumel extension-grade conductors, the cable ensures dependable thermoelectric compatibility with K-Type thermocouples while maintaining accurate signal transmission over extended distances. The PVC-insulated 2-core construction provides dependable electrical insulation for general industrial environments, while the stainless steel armour enhances mechanical strength without compromising flexibility. The cable is available in standard accuracy (±2.2°C or ±0.75%) and special accuracy (±1.1°C or ±0.4%) grades, allowing users to select the appropriate performance level based on process requirements and measurement precision.
