Key Features
- Mineral Insulation: Thermocouple wires insulated with solid magnesium oxide (MgO) for excellent thermal conductivity and electrical insulation
- Metal Sheath: Stainless steel or Inconel protection against physical damage and chemical corrosion
- Temperature Range: Operates in extreme temperatures up to 1200°C (2192°F) or higher
- Durability: Resistant to abrasion, moisture, and various chemicals
- Accuracy: Provides highly accurate temperature readings with minimal thermal lag
- Flexibility: Robust yet flexible for easier installation in tight spaces
Applications
Mineral insulated thermocouple cables are widely used in industrial temperature measurement applications:
- Power and control circuits of critical equipment
- Petrochemical, power generation, and metallurgy industries
- Kilns, ovens, and furnaces operating at high temperatures
- Aerospace and automotive environments requiring precision measurement
Construction
The cable is constructed by placing wire conductors inside a circular copper tube filled with dry magnesium oxide powder. The assembly is then pressed between rollers to reduce diameter. The mineral insulation is packed tightly around thermocouple wires, ensuring good thermal conductivity between the wires and outer sheath.
