Type B Thermocouple

Type B Thermocouples provide the Highest Temperature range for Air and Oxidizing environments with a 3,092°F (1700°) temperature on a continuous basis and up to 3,362°F (1850 °C) for short periods of time.

  • High Level of Accuracy and stability at high temperatures
    • Standard accuracy is 0.5% and SLE (Special Limits of Error) is 0.25% according to ASTM E-230
  • Temperature Range 32°F to 3,092°F (0°C to 1700°C) - continuous
    • Short term up to 3,362°F (1850 °C). Thermocouple probes made with smaller diameter bare wire will fail faster than sensors with larger diameters.
    • Typically temperatures of 392°F (200°C) and above is recommended
    • Temperature at 122°F (50°C) and below should be avoided. The thermocouple has the same milivolt output at 32° (0°C) and 108°F (42°C)
    • Should not be used in a Vacuum or Reducing atmosphere without a protected and sealed sheath.
  • Thermocouple Alloy - Positive wire is 70% Platinum/30% Rhodium and the Negative wire is 94% Platinum/6% Rhodium.
    • Type B (U) thermocouple connectors and thermocouple extension wire can be utilized to accurately transfer the full temperature range of Type B thermocouple probes.
    • The bare wire and the metal contact pins for Type B (U) are Copper (or Copper Maganese) for the Positive material and Copper for the Negative material.
