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
