Supported Applications
The Omega SGD-StressRelief series comprises 3-element stress relief strain gauges designed for rosette configurations. These sensors are engineered to measure multi-directional strain in structural and mechanical testing applications where principal stress directions must be resolved.
Operating Conditions & Performance
The available variants within the SGD-StressRelief series share a common electrical resistance of 120 Ω, as indicated by the model nomenclature. Specific performance parameters such as gauge factor, temperature range, and maximum strain limits are not detailed in the current documentation for this attribute-only listing.
Model Identification
- SGD-1.5/120-SR11: 3-element rosette configuration with SR11 geometry and 120 Ω resistance.
- SGD-1.5/120-SR13: 3-element rosette configuration with SR13 geometry and 120 Ω resistance.
- SGD-1.5/120-SR41: 3-element rosette configuration with SR41 geometry and 120 Ω resistance.
- SGD-1.5/120-SR43: 3-element rosette configuration with SR43 geometry and 120 Ω resistance.
Configuration Options
The series is offered in four distinct variants, differentiated by their specific stress relief pattern codes (SR11, SR13, SR41, SR43). All listed models feature a 1.5 mm grid dimension and a nominal resistance of 120 Ω.
Available Configurations
- Sensor Type: Rosette Strain Gauge (3-element).
- Nominal Resistance: 120 Ω across all variants.
- Grid Size: 1.5 mm as denoted in the part number prefix.
Key Product Differences
The primary distinction among the SGD-StressRelief models lies in their stress relief geometry, identified by the suffix codes SR11, SR13, SR41, and SR43. These designators correspond to specific rosette patterns optimized for different strain measurement requirements within the 3-element configuration.
