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.

1. Application

Thermocouple mineral insulated cable is widely applied in industry, are used for power and control circuits of critical equipment, such as Temperature measurement devices; a proven choice for high temperature probe fabrication.

2. Contruction

Itis made by placing one or more wire conductors inside a circular copper tube and filling the intervening spaces with dry magnesium oxide powder.

The overall assembly is then pressed between rollers to reduce its diameter (and increase its length).

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.
