SGD-3-ELEMENT45

Supported Applications

The Omega SGD series comprises precision rectangular rosette strain gauges with a single-plane, planar compact geometry configured for 0°, 45°, and 90° measurements. These miniature to large rectangular single plane rosettes are designed for general-purpose strain measurement applications requiring multi-directional data acquisition.

Operating Conditions & Performance

The series is available in nominal resistances of 120 Ω and 350 Ω. Temperature compensation options include configurations for steel (ST) or aluminum (AL). The product overview notes a maximum permitted bridge energizing voltage, denoted as Vrms (*), though specific numerical limits are not provided in the summary data.

Configuration Options

The SGD series supports multiple gage patterns and termination styles to accommodate different installation requirements. Key configurable attributes include:

• Gage Patterns: Models cover various rectangular planar rosette configurations, identified by numeric prefixes in the model code (e.g., 1, 2, 3, 6).
• Nominal Resistance: Available in 120 Ω and 350 Ω.
• Termination Types: Offered with ribbon leads or solder pads. Term pad options include BPT-1, BPT-2, and BPT-3 depending on the model group.
• Temperature Compensation: Configurable for steel (ST) or aluminum (AL).

The ordering convention follows the format: SGD-<GAGE PATTERN>-<NOMINAL RESISTANCE>-<TERMINATION>-<TEMP COMP>. For example, model SGD-3/350-RY21 represents a rectangular planar rosette with 350 Ω nominal resistance. Custom-designed strain gages are available with no minimum quantities upon consultation with engineering.

Key Product Differences

Variants within the SGD-3-ELEMENT45 series differ primarily by their specific gage pattern, which dictates the physical layout of the rosette elements. The model number prefix (e.g., 1, 2, 3, or 6) identifies these distinct patterns. Additionally, variants are distinguished by resistance value and termination style:

• Resistance Options: Models ending in /120 provide 120 Ω nominal resistance; models ending in /350 provide 350 Ω.
• Termination Codes: Suffixes such as RY21, RY23, RY81, and RY83 denote specific combinations of ribbon leads or solder pads paired with temperature compensation for steel (ST) or aluminum (AL).
