MI (Mineral Insulated) Thermocouples are high-performance temperature sensors designed for precise and reliable measurement in demanding industrial environments. Constructed with insulated thermoelements compacted in magnesium oxide (MgO) and encased in a stainless-steel or Inconel sheath, these thermocouples offer excellent mechanical strength, corrosion resistance, and vibration durability. Their mineral insulation ensures fast response times and stable performance across extreme temperature ranges.
