Base Metal AerOpak®


 
 

BASE METAL THERMOCOUPLE MINERAL INSULATED CABLE

Our standard mineral insulated (MI) thermocouple cable starts with fully annealed and cleaned tubing, high-purity (99.4% minimum) MgO insulation material and thermocouple wire that meet per ASTM E-230 Special Limits of Error.  In the ARi production process, precise dimensionality and uniform insulation maintained throughout the multiple reduction drawing and annealing process, assuring the end product integrity.  All commercially available thermocouple, conductor and heater wire materials are offered as standards from ARi.

The Quality Standard:

  • Useable under sever conditions that can destroy other types of thermocouple cable.
  • Withstands temperatures up to metal melting points.
  • Withstands corrosive conditions that are limited only by the choice of the outer sheath material.
  • Can be formed around a solid mandrel that is twice the sheath diameter without loss of integrity.  Can be welded, brazed or soldered to the other metals when proper techniques are used.
  • Standardized and shipped from ARi stock.

 

 

How To Order:

1. Specify by description.
Example: 1/16 inch Inconel 600 Sheath, Type K mineral insulated cable.

2. Specify by part number.
The part number is defined per the following:
EXAMPLE
062 - 2N - BKS

MI Base Metal Cable

062 - 2 N - B K S
(1)   (2) (3)   (4) (5) (6)

(1)  Sheath Diameter = 0.062 inch O.D.
(2)  Number of Conductors = 2 wires
(3)  Insulation/Purity
        N = MgO / 99.4% Min Purity
        M = MgO / 98.0% Min Purity
(4)  Sheath Material = Inconel 600
(5)  Wire Material = Calibration K
(6)  Calibration Accuracy
        S = Special Limits of Error, Class 1

 

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:
