Mineral Insulated Metal Sheathed Cable for Thermocouple and
Instrument Machine Connection
Overview: Mineral Insulated Metal Sheathed (MI) cables are a type
of high-performance cable specifically designed for use in harsh
environments and high-temperature applications. They are
particularly well-suited for thermocouple connections and the
integration of instrumentation in various industrial settings due
to their durability, reliability, and excellent thermal
conductivity.
Key Features:
Construction:
Metal Sheath: Typically made of stainless steel, copper, or other
alloys, providing robust mechanical protection against
environmental stressors such as moisture, chemicals, and physical
impacts.
Mineral Insulation: The insulation is usually composed of magnesium
oxide (MgO) powder, which offers excellent dielectric properties
and thermal conductivity, critical for accurate temperature
measurement.
Conductors: Usually made of thermoelectric materials (e.g., copper,
constantan, or other alloys) that form the thermocouple junction or
connect other instrumentation.
Performance:
High Temperature Resistance: MI cables can withstand extreme
temperatures (up to 1000°C or higher), making them ideal for
applications in furnaces, heat exchangers, and other high-heat
environments.
Low Thermal Drift: The use of inorganic insulation minimizes
thermal drift, ensuring stable and accurate temperature readings.
Electrical Isolation: The MgO insulation provides excellent
electrical isolation, reducing noise and improving the accuracy of
temperature measurements.
Advantages:
Durability: The robust metal sheath protects against physical
damage, making MI cables suitable for use in rugged industrial
environments.
Corrosion Resistance: Metal sheaths, particularly stainless steel,
offer excellent resistance to corrosion, extending the lifespan of
the cable.
Versatility: MI cables can be used for various thermocouple types
(e.g., Type K, J, T, etc.) and can be adapted for different
instrumentation applications.
Moisture and Chemical Resistance: The design protects against
moisture ingress and exposure to chemicals, ensuring reliable
performance in harsh conditions.
We add heat shrink tubing and plastic film to make sure high insulated resistance.
Except marking notes, we also have pass card and test report for every coil cable.
