MgO Filled Thermocouples for Industrial Temperature Measurement

MgO Filled Thermocouples commonly abbreviated as MI Thermocouples are used for indutrial temperature measurement using a pair of dissimilar metals which are insulated with a compact mass of MgO. Seperated elements filled with MgO are covered using an outer tube with a variety of MOC which may be SS, Inconel or its grades. They are rugged in nature and bendable, and their fairly high-temperature ratings make MI thermocouples a popular choice for a multitude of temperature measuring applications.
