BARE-SH-DH-OV-ELEMENTS

Supported Applications

The Omega Ceramic Beaded Thermocouple Elements series provides precise temperature measuring elements assembled from high-grade materials. These sensors are designed for applications requiring thermocouples checked against standard temperature-millivolt curves to assure calibration accuracy.

Operating Conditions & Performance

Omega's ceramic beaded thermocouple elements meet or exceed ANSI Special Limits of Error and EN 60584-2: Tolerance Class 1. The series supports multiple insulation types with distinct temperature ratings:

• X C Insulation: Rated to 1200°C (2200°F)
• S H, D H, and O V Insulators: Rated to 1600°C (2900°F)
• F S Insulators: Rated to 1200°C (2200°F)

Note: These ratings apply to the insulation only; users must check operating limits of the wire. The standard overall length for listed configurations is 300 mm (12").

Configuration Options

The series offers a broad configuration envelope across thermocouple types, wire sizes, and insulator geometries.

Sensor Types & Wire Sizes

• Fish Spine (FS) Insulators: Single hole options available in FS-260, FS-200, and FS-110 profiles depending on wire size.
• Double Hole Oval (OV) Insulators: Available for 8, 14, and 20 AWG configurations.

Ordering & Customization

Optional lengths are available. When ordering, the last digits of the part number indicate length in inches or fractions; users may change these to show actual desired length. For orders over 5', consult Sales Department for pricing.

Key Product Differences

Variants within this series differ primarily by insulator geometry, wire gauge, and thermocouple type combination. The "To Order" table defines specific model numbers such as Bare-8-J-12 (8 AWG Type J with no insulators) or DH-1-14-K-12 (14 AWG Type K with double hole ceramic bead insulators). For R, S, and B thermocouples using RAT, SAT, BAT series elements, users are directed to visit the manufacturer online. Detailed dimensional data for specific bead sizes is available via the Insulator Dimensional Chart in the source documentation.
