Mineral Insulated Thermocouple

A mineral-insulated thermocouple (MI thermocouple) in which wires are usually made of materials such as chromel and alumel or other combinations depending on the desired temperature range and application insulated within a compacted mineral powder, typically magnesium oxide (MgO).

Type:   J, K, T, N
Element Dia. (in mm):   3, 4, 5, 6, 8 (in mm) & other sizes on demand.
Sheath Material:   SS-310, SS-316, Inconel.
Configuration: Simplex / Duplex.

The mineral insulation provides excellent electrical insulation and thermal conductivity, allowing the thermocouple to accurately measure temperatures in harsh environments, including high temperatures, corrosive atmospheres, and high-pressure conditions. The compacted mineral insulation also provides mechanical strength and protection to the thermocouple wires.

They offer high accuracy, stability, durability, and resistance to vibration, making them suitable for demanding applications.
