Mineral insulation is used to insulate thermocouple wires from each other and from the surrounding metal probe sheath. The sheath is filled with a highly compacted magnesium oxide powder that prevents the wires from coming into contact with each other beyond the fixed junction. The high density of the mineral powder gives the thermocouple fast response because it promotes rapid heat transfer between the wires and the sheath. Mineral insulation also helps protect thermocouple wires from environmental damage such as corrosion, prevents electrical interference, and allows the cable to remain flexible while maintaining its mechanical strength.

Type K mineral insulated thermocouples (Nichrome/Nickel Aluminum) are the most common type of thermocouple, offering accuracy and flexibility over a wide range of temperatures.
