A mineral-insulated (MI) thermocouple cable is a specialized type of cable used for temperature measurement in various industrial applications. It consists of two dissimilar metal wires (typically different alloys) joined together at one end to form a thermocouple junction. The junction is then enclosed within a mineral insulation material, typically magnesium oxide (MgO), which provides electrical insulation and mechanical protection.
The mineral insulation is packed tightly around the thermocouple wires, ensuring good thermal conductivity between the wires and the outer sheath. The outer sheath is usually made of a corrosion-resistant material such as stainless steel or Inconel.
The MI construction offers several advantages for thermocouple applications. It provides excellent resistance to high temperatures, mechanical stress, and environmental hazards. The mineral insulation helps to protect the thermocouple wires from oxidation, contamination, and moisture ingress, ensuring accurate and reliable temperature measurements.
Mineral-insulated thermocouple cables can be customized with different wire materials and sheath sizes to suit specific temperature ranges and environmental conditions. They are commonly used in industries such as petrochemical, power generation, metal processing, and aerospace, where precise and robust temperature measurement is required.
Positive leg(KP leg) is universally known as Ni90Cr10 or Chromel.
Negative leg( KN leg) is universally known as Alumel or NiAlCo/ NiSi3
Thermocouple wire Type K is supplied in the form of bare wire with dimension from 0.1mm to 8.0mm
For oxidised wires the available dimensions are 1.2 to 8mm.
Thermocouple wire can also be supplied in the form of stranded wire.

Type K Thermocouple (Nickel-Chromium / Nickel-Alumel): The type K is the most common type of thermocouple. It's inexpensive, accurate, reliable, and has a wide temperature range. The type K is commonly found in nuclear applications because of its relative radiation hardness. Maximum continuous temperature is around 1,100C.
