SGT-Dual-Strain-Gages

Supported Applications

The Omega SGT series consists of transducer quality dual parallel grid strain gauges designed specifically for bending applications. These sensors are engineered to measure strain in scenarios requiring a dual-grid configuration, providing the necessary sensitivity and layout for structural analysis involving flexure.

Operating Conditions & Performance

The SGT series is characterized by its transducer quality construction intended for precision measurement tasks. The product overview identifies these units as "Transducer Quality Strain Gage" devices optimized for bending strain measurements. While specific numerical ranges for operating temperature, gauge factor, or maximum permitted bridge energizing voltage are referenced in the source documentation (noted with an asterisk regarding Vrms), exact values must be verified against the specific model selection and associated data sheet tables.

Configuration Options

The series offers a configurable envelope defined by grid patterns, resistance values, termination types, and temperature compensation materials. The ordering structure follows the format: SGT-<GAGE PATTERN>-<RESISTANCE>-<TERMINATION>-<TEMP COMP>.

• Grid Patterns: Available in various dual parallel configurations identified by numeric codes (e.g., 2, 2C, 2D, 3, 3N, 6, 7) to suit different bending measurement geometries.
• Nominal Resistance: Options include 350 Ω and 1000 Ω variants as indicated in the model numbering (e.g., SGT-2/350 vs. SGT-7/1000).
• Termination Types: Electrical connections are available with Ribbon Leads or Solder Pads, denoted by suffixes such as DY11, DY13, DY41, and DY43.
• Temperature Compensation (Temp Comp): The series supports compensation for Steel (ST) and Aluminum (AL), allowing the gauge to be matched to specific test specimen materials.
• Packaging: Units are supplied in packages of 5, as noted in the ordering example structure.

Key Product Differences

Variants within the SGT series differ primarily by their grid pattern code and resistance value. For instance, models such as SGT-3/350-DY11 feature a specific dual grid pattern for bending strain with 350 Ω nominal resistance, while other variants like SGT-7/1000-DY43 utilize a different grid layout paired with 1000 Ω resistance. The termination suffix (e.g., DY11 vs. DY43) distinguishes the electrical connection method and lead configuration for each specific model.
