What is MI cable?

A mineral insulated thermocouple cable consists of two conductors (sometimes even four or six) of dissimilar metals. These conductors are joined on the side on which temperature should be measured (hot junction). When properly joined, a voltage is produced that can be read to determine temperature. The dissimilar metals are insulated with high quality magnesium oxide and covered with a corrosion resistant sheath material, such as Inconel or Stainless steel. Mineral insulated thermocouples can provide stable temperature measurement readings and are often used for high temperatures (up to 1250⁰C) in hazardous environments.
