HIGH TEMPERATURE CABLE (MI CABLE)
ARi has developed a complete line of metallic sheath ceramic insulated thermocouple cable for operation in the range of 1100 °C (2012 °F) to 2200 °C (3992 °F). This is a high quality product employing clean room techniques in manufacturing and inspection. It is useable either for fabrication of high temperature thermocouples or leadwire cable for thermocouples.
Electrical Characteristics
| INSULATION RESISTANCE | Room temperature insulation resistance will be a minimum of 1000 megohms at 50 VDC for 1.0-1.5 mm O.D. and 500 VDC for 3.18-6.35 mm O.D. Insulation resistance at 1000 °C will be a minimum of 6100 ohms-meter at 6 VDC. Proper bending will not cause a loss of insulation resistance. |
| WIRE HOMOGENITY | Will be such that a sharp gradient of 800 °C will produce not more than a ± 0.1 millivolt output. |
Physical Characteristics
| FORMABILITY: Forming is limited to a minimum inside bend radius of five (5) sheath diameters for Inconel 600 and Platinum alloys and 10 diameter for Tantalum. | |
| PRESSURE | Can withstand external pressure of 3500 Kg/cm² at room temperature. |
| FABRICATION | AerOpak® can be GTAW welded and brazed without changing insulation resistance. Welding on Tantalum must be done in either vacuum or inert atmosphere. |
| Random lengths will be provided unless requested otherwise. Specific lengths are available in all standard products, up to the maximum single length indicated in the Tables. Length tolerance: ± 15 cm. | |
| Each section of AerOpak® is moisture-sealed at both ends with a suitable resin. When ordering, allow 2.5 cm to be removed from each end. Both ends can be provided with a storage seal (seal welding) in place of the temporary resin seal. | |
| AerOpak® in straight lengths will have a curvature not exceeding six (6) mm in one (1) meter as measured against a straight edge lying free. | |
| DIAMETER | Shall be within ± 0.05mm of nominal. Ovality will not exceed 0.003mm. |
| INTEGRITY | There shall be no porosity, inclusions, pit or scratches which exceed 10% wall thickness, or 0.003 mm (whichever is greater). |
How To Order:
1. Specify by description.
Example: ¼ inch Inconel 600 Sheath, Type R mineral insulated cable.
2. Specify by part number.
The part number is defined per the following:
EXAMPLE

| 125 | - | 2 | N | - | B | R | - |
30 |
| (1) | (2) | (3) | (4) | (5) | (6) |
(1) Sheath Diameter = 0.125 inch O.D.
(2) Number of Conductors = 2 wires
(3) Insulation/Purity
N = MgO / 99.4% Min Purity
(4) Sheath Material = Inconel 600
(5) Wire Material = Calibration R
(6) Wire Gage
30 = 30 AWG (0.010 inch)
3. Specify total quantity. If cut lengths are required, specify length of each piece. Accuracy of a cut is +/- 1/2% of the length or +/- 1/2 inch (12.7mm), which ever is larger.
4. Sizes up to 0.375 inch (9.53mm) can be shipped UPS or FedEx.
5. Shipping tolerance for random lengths is +15% / -10% unless specified otherwise.
6. Standard shipping coil sizes and weight:
