K-Type Thermocouple Cable Brown with Black Yarn For Industrial Heating
Product Overview
This K-type thermocouple cable (2×0.71mm) from Huona New Material is a high-temperature signal transmission component engineered for industrial temperature measurement scenarios. It features dual 0.71mm-diameter conductors (Chromel-KP positive, Alumel-KN negative) and integrated fiberglass insulation & outer sheath, delivering stable thermoelectric potential transmission while withstanding harsh high-temperature environments. With Class 1 accuracy and a continuous operating temperature of up to 700℃ (intermittent 800℃), this cable is widely used in industrial furnaces, heat treatment equipment, and high-temperature manufacturing processes—combining excellent heat resistance, reliable insulation performance, and clear polarity identification (yellow +, red -) for efficient on-site installation.
Fiberglass Insulation/Sheath: The integrated fiberglass structure (high-purity glass fiber braid) resists 700℃ continuous high temperature, with no insulation breakdown or performance decay after 1000 hours of operation at 650℃—far exceeding the 260℃ limit of PVC-insulated cables.
Stable Thermoelectric Potential: At 700℃, the cable's thermoelectric potential deviation is ≤±1.5℃ (Class 1 accuracy), ensuring consistent temperature measurement for precision heat treatment (e.g., automotive part quenching).
2. Optimized Conductor & Structural Design
2 ×0.71mm Conductor: The single-strand 0.71mm diameter balances conductivity (loop resistance ≤2.5Ω/m) and flexibility, fitting narrow installation spaces (e.g., furnace wall gaps) while avoiding signal interference from multi-strand stranding.
Tight Braid Structure: The fiberglass sheath has a braiding density ≥95%, effectively isolating high-temperature dust, molten droplets, and weak corrosive gases—extending service life in industrial environments.
3. Easy Installation & Reliability
Clear Polarity Identification: Yellow/red color coding for positive/negative conductors eliminates wrong connections, reducing on-site debugging time by 40% and preventing equipment damage from reverse polarity.
Class 1 Accuracy: Meets strict temperature control requirements (error ≤±0.4% t at 400-700℃), suitable for high-precision scenarios like aerospace component annealing.
