Supported Applications

The Omega SGD series comprises precision rectangular stacked rosette strain gages configured with a 0°/45°/90° pattern. These compact, three-element sensors are designed for measuring multi-directional strain in structural and mechanical testing applications.

Operating Conditions & Performance

The series offers nominal resistances of 120 Ω and 350 Ω across small, medium, and large gage sizes. Maximum permitted bridge energizing voltage (Vrms) varies by model configuration:

SGD-2 Series: Ranges from 3 Vrms to 7 Vrms depending on resistance and termination.
SGD-3 Series: Ranges from 4.5 Vrms to 10 Vrms.
SGD-7 Series: Ranges from 9 Vrms to 20 Vrms.

Gage dimensions are defined by active grid length (A), active grid width (B), and matrix carrier size (C/D). For example, the SGD-2 pattern features a 2.00 mm (0.079 inch) grid A dimension with a 5.60 mm (0.220 inch) carrier C dimension.

Configuration Options

The series supports multiple configuration options to accommodate different installation and material requirements:

Gage Sizes: Available in three sizes identified by the model prefix: SGD-2 (5.6 mm carrier), SGD-3 (7.1 mm carrier), and SGD-7 (11.4 mm carrier).
Nominal Resistance: 120 Ω or 350 Ω.
Electrical Connections: Ribbon Leads or Solder Pads.
Termination Material: Steel (ST) or Aluminum (AL).
Temperature Compensation: BPT-1, BPT-2, and BPT-3 options correspond to the specific gage size series.

Packaging is provided in packages of 5. Custom-designed strain gages are available with no minimum quantities; consult engineering for details.

Key Product Differences

The SGD-TRIAXIAL model number follows the format SGD-<SIZE>/<RESISTANCE>-<TERMINATION>. The size code (2, 3, or 7) determines the physical dimensions and maximum voltage rating. Resistance is specified as either 120 or 350 Ω.

Termination codes distinguish between electrical connection types and material compatibility:

Ribbon Leads: Models ending in -RY5 (e.g., SGD-2/120-RY51).
Solder Pads: Models ending in -RY6 (e.g., SGD-2/120-RY61).
Material Specifics: The final digit indicates the termination material: 1 for Steel (ST) and 3 for Aluminum (AL). For instance, RY51 denotes Ribbon Leads with ST termination, while RY53 denotes Ribbon Leads with AL termination.
