SGD-2-ELEMENT90

Supported Applications

The Omega SGD-2-ELEMENT90 series consists of Precision Strain Gage Corner Tee Rosettes configured as a Biaxial, 0 ° - 90 ° arrangement. These strain gages are designed for measuring strain in materials where biaxial stress analysis is required.

Operating Conditions & Performance

The series supports nominal resistances of 120 Ω and 350 Ω. Maximum permitted bridge energizing voltage varies by model, ranging from 3 Vrms to 20 Vrms depending on the specific resistance, size, and termination type. The data sheet notes that for a complete dimensions key, users should visit the manufacturer online.

Configuration Options

The SGD-2-ELEMENT90 series is available in three primary grid sizes: Small (1 mm), Medium (3 mm), and Large (6 mm). Each size offers configurations for different termination methods and temperature compensation materials.

• Nominal Resistance: 120 Ω or 350 Ω.
• Termination Types: Ribbon Leads or Solder Pads.
• Temperature Compensation (Temp Comp): ST for Steel and AL for Aluminum.
• Packaging: Models are supplied in packages of 5 units per package, as indicated by the "Pkg of 5" notation on model numbers.
• Customization: Custom-designed strain gages are available with no minimum quantities; engineering consultation is required for these configurations.

Key Product Differences

The SGD-2-ELEMENT90 biaxial 0°–90° corner T-rosette strain gauge is configured through its model number (SGD-<size>-<resistance>-RYB<termination>), giving a matrix of options:

• Nominal resistance — 120 Ω and 350 Ω options.
• Termination / temperature-compensation code — RYB variants such as RYB21, RYB23, RYB81 and RYB83.

Example designations include SGD-1/120-RYB83 (120 Ω) and SGD-1/350-RYB21 (350 Ω).
