Product Description
Type B Thermocouple Wire 0.5mm IEC 60584/ASTM E230 Extreme High-Temp Precision Sensing
B-type noble metal thermocouple wire (0.5mm diameter) from Huona New Material is a high-performance high-temperature sensing element composed of Pt30Rh (positive electrode, 30% rhodium-70% platinum alloy) and Pt6Rh (negative electrode, 6% rhodium-94% platinum alloy. Manufactured via vacuum smelting, multi-pass precision drawing, and high-temperature homogenization annealing, this wire excels in ultra-high-temperature scenarios with continuous operation up to 1600℃ and short-term tolerance of 1800℃.
Standard Designations & Core Material Foundation
- Thermocouple Type: B-type (Pt30Rh/Pt6Rh; noble metal thermocouple, compliant with IEC 60584-2 Class 1)
- Key Specification: 0.5mm diameter (tolerance: ±0.003mm)
- Chemical Composition: Positive (BP): Pt70Rh30; Negative (BN): Pt94Rh6
- Compliant Standards: IEC 60584-2, GB/T 1672-1997, ASTM E230
- Manufacturer: Huona New Material, certified to ISO 9001 and IATF 16949
Key Performance Advantages
Unmatched Ultra-High-Temperature Performance
- Wide Temperature Adaptability: Operates stably in the range of 0-1600℃ continuously and withstands short-term (≤30min) exposure to 1800℃
- Minimal Thermoelectric Potential Drift: After 1000 hours at 1500℃, drift is <4μV (equivalent to temperature error <0.3℃)
Optimized 0.5mm Diameter Performance
- Balanced Sensitivity & Mechanical Strength: Thermal response time (τ₅₀) ≤2.5s in air at 1000℃ with tensile strength ≥380 MPa
- Cost-Effective Design: Higher structural strength and longer service life compared to thinner wires
Excellent Environmental Resistance & Processability
- Strong Corrosion Resistance: Resists corrosion from molten glass, molten metal, and high-temperature flue gas
- Good Ductility & Weldability: Elongation ≥15% enables bending to minimum radius of 1.0mm
