Mineral Insulated Cable - AerOpak®

Special Limits Of Error As Defined in ASTM E-230

High Purity Magnesium Oxide (MgO) Insulation 99.4% Pure

MI Thermocouple Cable Furnace Our product line of AerOpak® Mineral Insulated cable can be used under the most severe conditions that can destroy other types of thermocouple cable. Based on our rugged construction and with a large variety of sheath materials available, AerOpak® cable can be used in corrosive conditions up to the maximum range of the materials selected.

AerOpak® can be supplied in long lengths and can be formed or bent to a radius equal to twice the sheath diameter without loss of integrity. It can easily be welded or brazed to other metals when proper techniques are used.

Special non-destructive testing is available on in-process and finished thermocouple cable. Types of test available include Thermocouple Temperature Calibration, Radiography, Liquid Penetrant, Helium Leak, Dimensional, and Insulation Aeropak Cable Image Resistance. ARi standards are traceable to the National Institute of Standards and Technology (NIST).

With our manufacturing capabilities, we can produce high quality AerOpak mineral insulated cable with outside sheath diameters from 0.020" to 0.750". Metric sizes, custom sizes, and heavy wall thickness cable is available on request.

Please contact us for further information or any special requirements you may have.
