Product Description
Type K Thermocouple Extension Cable (Stainless Steel Flexible Conduit, 2×0.5mm, 1m, Standard Plug & Socket)
Product Overview
Type K thermocouple extension cable (as shown) from Huona New Material is a high-temperature signal transmission assembly featuring Type K (Chromel/Alumel) conductors, stainless steel flexible metal conduit, and standard Type K thermocouple plug & socket (IEC color-coded). Engineered for harsh industrial environments, it delivers stable thermoelectric performance across -40℃ to 700℃ (continuous) / 800℃ (short-term). Ideal for furnace temperature monitoring, industrial automation, and high-temperature testing, it offers excellent mechanical protection, flexible routing, and reliable signal transmission.

Key Core Advantages (Centered on Stainless Steel Conduit & Plug/Socket)
1. Superior Mechanical & High-Temperature Protection
- Stainless Steel Conduit Durability: 304 stainless steel flexible conduit resists abrasion, crushing, and high-temperature exposure (700℃ continuous), protecting inner fiberglass-insulated conductors from mechanical damage and environmental contamination.
- Flexible Routing: Corrugated design allows bending to a minimum radius ≥10× cable diameter, suitable for tight spaces and complex industrial layouts.
2. Reliable Signal Transmission & Compatibility
- Class 1 Accuracy: Thermoelectric potential error ≤±1.5℃ (0-400℃) / ±0.4% t (400-700℃), ensuring accurate signal transmission for industrial temperature measurement.
- Standard Plug & Socket: IEC color-coded Type K plug/socket ensures universal compatibility with most thermocouple meters, data loggers, and control systems, eliminating wiring errors.
3. Environmental Adaptability & Longevity
- Wide Temperature Range: Operates stably at -40℃ to 700℃, with no insulation breakdown or conductor drift in high-temperature industrial environments.
- Corrosion & Oil Resistance: Stainless steel conduit and fiberglass insulation resist mild chemical corrosion, oil mist, and furnace flue gas, extending service life by 3× compared to PVC-insulated cables.
