304-INC-MM-CLAD

Supported Applications

The Omega Metric OMEGACLAD™ Thermocouple Wire series provides mineral-insulated, metal-sheathed thermocouple wire for temperature sensing applications. The product consists of a metal sheath containing high-purity magnesium oxide (MgO) insulation and internal thermocouple wires.

Operating Conditions & Performance

The series is available in diameters ranging from 0.25 to 8.0 mm. A technical note specifies that the compacted magnesium oxide used as insulation is hygroscopic (absorbs moisture). The wire bends easily, facilitating installation.

Sheath Materials

• 304 Stainless Steel
• 310 SS
• 316 SS
• 321 SS
• Inconel® 600
• Super OMEGACLAD™ XL Sheaths

Thermocouple Types

• Type E (CHROMEGA™-ALOMEGA™)
• Type J
• Type K
• Type N (available with Inconel sheath; change "K" in model number to "N")
• Type T

Configuration Options

The series supports a wide range of configurations defined by the model number format: <Sheath Material Code> - <Wire Calibration> - MO - <Sheath Diameter in mm>. Lengths are specified in meters with a minimum order of 5 meters. OMEGACLAD™ wire is supplied to ±10% of the specified length.

Special Options

• Special Limits of Error: Add suffix "SLE" to the model number; adds 20% to price.
• Hastelloy-X Sheath: Change "304" in the Model Number to "HASTX" (consult Sales for price).
• Custom Assemblies: Special sheathing, insulation, and thermocouple alloys are available on special order.

Key Product Differences

Variants differ by the combination of sheath material code (e.g., 304, 310, 316, 321, INC for Inconel), thermocouple calibration letter (E, J, K, N, T), and diameter in millimeters. The "SLE" suffix denotes a Special Limits of Error configuration.

Ordering Example

Model number 304-K-MO-1.5MM-10 represents 10 m of Type K CHROMEGA™-ALOMEGA™ wire with a 304 SS sheath and 1.5 mm diameter.

Accessories

A Thermocouple Wire Stripper is available for metal-sheathed or OMEGACLAD™ wire (see PST Series Strippers).
