Simplex Mineral Insulated Thermocouple Cable (MI Cable) with Stainless steel SS316

. Simplex mineral insulated thermocouple cable
. Differnet sheath diameters from 0.25mm to 12.7mm
. Sheath material: SS316
. Standard no. of conductors: 2 conductors
. Internal conductors: Thermocouple J, K, T, E, N
. MI cables with high reliability and high heat resistance
. MI cables withstands vibration and pressures

Technical Data

. Mineral insulated cables are the industry standard, proven choice for high temperature probe fabrication.
. 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.
. The small mass and high thermal conductivity of a properly made cable promotes rapid response of the finished thermocouple assembly.
. Sheath materials can be selected to offer strong resistance against corrosive environments and extremely high temperature effects.

Sheath Material of SS316
: Chemical instrument construction, nuclear power plants, reactor instrumentation, furnace construction, sulphite, chemical pulp, textile, dye, fatty acid, photochemical and pharmaceutical industries.
Max. continuous temperature: 925°C
Heat resistance: Good oxidation resistance in intermittent service to 800°C and in continuous service to 925°C. 
Corrosion resistance: Good resistance to a wide range of chemicals. Highly resistant to complex sulphur compounds used in pulp and paper processing. Also resists attack of marine and corrosive industrial atmospheres.
Welding: Good characteristics suited to all standard welding methods.
