Product Description

Type B Thermocouple Wire

Product Overview

Type B thermocouple wire is a high-performance precious metal thermocouple consisting of two platinum-rhodium alloys: a positive leg with 30% rhodium and 70% platinum, and a negative leg with 6% rhodium and 94% platinum. Designed for extreme high-temperature environments, it is the most heat-resistant among common precious metal thermocouples, excelling in stability and oxidation resistance at temperatures exceeding 1500°C. Its unique dual-platinum-rhodium composition minimizes drift caused by platinum evaporation, making it ideal for long-term high-temperature measurement.

Standard Designations

  • Thermocouple Type: B-type (Platinum-Rhodium 30-Platinum-Rhodium 6)
  • IEC Standard: IEC 60584-1
  • ASTM Standard: ASTM E230

Key Features

  • Extreme Temperature Resistance: Long-term operating temperature up to 1600°C; short-term use up to 1800°C
  • Low EMF at Low Temperatures: Minimal thermoelectric output below 50°C, reducing cold junction error impact
  • Superior High-Temp Stability: ≤0.1% drift after 1000 hours at 1600°C
  • Oxidation Resistance: Excellent performance in oxidizing atmospheres; resistant to platinum evaporation
  • Mechanical Strength: Maintains ductility at high temperatures, suitable for harsh industrial environments

Product Specifications

Item Specification
Length per Spool 5m, 10m, 20m (due to high precious metal content)
Surface Finish Annealed, bright (no surface contamination)
Packaging Vacuum-sealed in argon-filled titanium containers to prevent oxidation
Calibration Traceable to international temperature standards with certified EMF curves
Custom Options Precision cutting, surface polishing for high-purity applications

Typical Applications

  • High-temperature sintering furnaces (ceramic and refractory materials)
  • Metal smelting (superalloy and special steel production)
  • Glass manufacturing (float glass forming furnaces)
  • Aerospace propulsion testing (rocket engine nozzles)
  • Nuclear industry (high-temperature reactor monitoring)

We provide Type B thermocouple assemblies with ceramic protection tubes and high-temperature connectors. Due to the high material value, sample lengths are limited to 0.5-1m upon request, accompanied by full material certificates and impurity analysis reports. Custom configurations for specific furnace environments are available
