Mineral Insulated Thermocouples, Magnesium Oxide Insulated (MgO)

  • MgO thermocouples are versatile sensors for use in process temperatures up to 2400°F and are also recommended in high moisture, liquid, high pressure, and corrosive environments
  • Attributes are high dielectric strength, durability, malleability and quick response to temperature fluctuations
  • The uniform thickness of wires and magnesium oxide insulation provides mechanical strength, plus corrosion and moisture resistance
  • Densely- packed, high- purity MgO insulation is used in all calibrations and sheath materials
  • Minimum Bend Diameter is equal to two times the outside diameter

Sheath Ratings
Continuous maximum temperature ratings of sheath in oxidizing atmospheres

Base Metal Thermocouple Elements (BME)

  • Industrial base metal elements and assemblies designed for the most severe environments
  • Styles selected by temperature range, ambient atmosphere, and media conditions
  • Select sizes and shapes based upon application requirements
  • Select by the need for accuracy and speed of response

Base Metal Assemblies (BMA)

  • Industrial base metal elements and assemblies designed for the most severe environments
