Key Core Advantages (Centered on Bendable Design & IP65 Protection)

1. Flexible Bendable Sheath

• Customizable Bend Angles: The 304 stainless steel sheath can be bent to custom angles (e.g., 90°, 45°) to access confined or hard-to-reach measurement points, ideal for complex industrial equipment.
• Maintains Performance: Bending does not compromise the thermocouple's performance or structural integrity, ensuring reliable measurements in non-linear installation paths.

2. Wide Temperature Range & Stability

• Continuous Operation: Up to 1100℃, short-term up to 1200℃, suitable for a broad range of industrial temperature monitoring applications.
• Thermoelectric Stability: Stable EMF output with minimal drift under long-term use, ensuring reliable and consistent measurement data.

3. High Precision & Accuracy

• Class 1 Accuracy: Thermoelectric potential error ≤±1.5℃ (0–400℃) / ±0.4% t (400–1100℃), meeting the precision requirements for industrial process control.
• Fast Thermal Response: Compact sheath design provides a thermal response time (τ₅₀) ≤2s in air at 800℃, ideal for dynamic temperature monitoring.

4. Rugged Construction & Environmental Resistance

• 304 Stainless Steel Sheath: Resists corrosion, abrasion, and mechanical impact, extending service life in harsh industrial environments (e.g., petrochemical, marine).
• IP65 Connection Head: Blue cast aluminum head with IP65 protection, preventing ingress of dust and water, suitable for outdoor and wet industrial settings.

5. Versatile Processability

• Flexible Termination: Connection head accommodates standard terminal blocks for easy wiring and maintenance.
• Customizable Options: Supports various sheath lengths, diameters, and bend angles to meet specific application needs.
