Duplex Mineral Insulated Thermocouple Cable (MI Cable) with Stainless steel SS304

Feature:
1). Mineral insulated cables are the industry standard, proven choice for high temperature probe fabrication.
2). Bulk MI cable is rugged, inexpensive, reliable, widely accepted by industry, and readily available in standard configurations, the metal sheath provides a self-armoured cable, which is mechanically robust even at small diameters.
3). The small mass and high thermal conductivity of a properly made cable promotes rapid response of the finished thermocouple assembly.
4). Sheath materials can be selected to offer strong resistance against corrosive environments and extremely high temperature effects.

Sheath Material of SS304 

Applications: Nuclear power plants, chemical equipment, textile and paper industry, fat, soap and nitric acid industries, food processing, dairy and brewery works.
Max. continuous temperature: 900°C (1650°F).
Heat resistance: Good oxidation resistance in intermittent service to 870°C and continuous service to 900°C. Continuous use of 304 in 425 to 850°C range not recommended but often performs well in temperatures fluctuating above and below this range.
Corrosion resistance: Excellent in a wide wariety of corrosive media including hot petroleum products and steam combustion gases.
Welding: Suitable for all standard welding methods.
