Mineral insulated (MI) cables work based on several key principles
related to their construction and the properties of their
materials. The following is a detailed explanation:
Mineral insulated thermocouple cable is a type of thermocouple
assembly that uses a mineral insulation material, typically
magnesium oxide (MgO), to provide electrical insulation between the
thermocouple wires. This design allows for high-temperature
measurements and provides several advantages over traditional
thermocouple cables. Here are some key features and benefits:
Features:
High-Temperature Tolerance: Mineral insulated thermocouple cables
can withstand extreme temperatures, often exceeding 1000°C
(1832°F), making them suitable for industrial applications in harsh
environments.
Durability: The outer sheath, typically made of stainless steel or
other alloys, offers excellent mechanical protection, making it
resistant to abrasion, corrosion, and other physical stresses.
Compact Design: The small diameter of the cable allows for easy
installation in tight spaces and enables better thermal response
times.
Low Thermal Mass: Due to the compact construction, these cables
have low thermal mass, which helps in achieving faster response
times to temperature changes.
Versatility: They can be used in a variety of applications,
including furnaces, kilns, ovens, and other high-temperature
processes.
- Conductor: MI cables typically use a copper or aluminum conductor at the
core. This conductor is responsible for carrying the electrical
current. Copper is often preferred for its high electrical
conductivity, which allows for efficient transmission of
electricity with low resistance and minimal power loss.
- Insulation: The conductor is surrounded by a layer of mineral insulation,
usually made of magnesium oxide (MgO). MgO has excellent thermal
and electrical insulation properties. It provides a high level of
electrical resistance, preventing the current from leaking out and
ensuring that it remains within the conductor.
- Sheath: The outermost layer is a metal sheath, commonly made of copper,
stainless steel or aluminum. The sheath serves multiple purposes.
It provides mechanical protection to the cable, safeguarding the
inner components from physical damage, such as impacts, abrasion
and moisture ingress.
