Mineral Insulated Thermocouples


Mineral insulated thermocouples are fast-responding, durable, and capable of handling high temperatures.


A protective metal outer sheath allows the use of smaller diameter conductors, while the rock hard compacted MgO insulation enhances the sensor’s ability to read temperature by transferring heat quickly to the measuring junction.


Mineral insulated thermocouples outperform bare wire thermocouples in most applications.

Performance Features

    • Easily handles temperatures up to 2200° F (1200° C)
    • Meets or exceeds initial calibration tolerances per ASTM E 230
    • Mineral insulation protects thermocouple from moisture and thermal shock and permits operation in high temperature, high pressure environments
    • Diameters as small as 0.010 in. (0.25 mm)
    • Flexibility of insulation allows thermocouple to bend without risk of cracking to meet design requirements
    • Outer sheath protects wires from oxidation and hostile environments
    • Wide range of sheath materials, diameters, and calibrations to meet specific requirements
    • Custom options include special lead lengths, lead wires, and terminations
