Supported Applications

The Omega SGT Half Bridge Uniaxial series consists of transducer quality strain gauges featuring dual linear patterns with a half-bridge design and common tab. These sensors are designed for transducer applications on beams with contraflexure points (points of opposite bending) and reversed bending beams. The series is used specifically for bending strain applications.

Operating Conditions & Performance

The SGT-Half-Bridge-Uniaxial gauges operate as uniaxial measurement devices configured in a dual linear half-bridge arrangement to support double bend transducer applications. Maximum permitted bridge energizing voltage (Vrms) varies by model and resistance, ranging from 6.5 Vrms for specific configurations up to 20 Vrms depending on the grid pattern and termination type.

Key Performance Parameters

Measurement Type: Uniaxial Strain
Nominal Resistance Options: 350 Ω or 1,000 Ω
Maximum Bridge Energizing Voltage (Vrms): Values range from 6.5 V to 20 V based on the specific model and resistance.

Configuration Options

The series offers configurable options for termination, temperature compensation, grid dimensions, and carrier sizes to accommodate different transducer designs. Custom gauges are available upon request.

Termination & Electrical Connection

Ribbon Leads: Available on models with TY1x suffixes (e.g., SGT-1LH/350-TY11).
Solder Pads: Available on models with TY4x suffixes (e.g., SGT-1LH/350-TY41).

Temperature Compensation Materials

Steel (ST): Temperature matched to steel substrates.
Aluminum (AL): Temperature matched to aluminum substrates.

Dimensional Configurations

The series includes two primary carrier sizes with varying grid dimensions:

9.2 mm Carrier Width: Models such as SGT-1LH feature a 9.2 mm (0.362 inch) carrier width.
14.3 mm Carrier Width: Models such as SGT-2LH feature a 14.3 mm (0.563 inch) carrier width.

Packages are supplied in quantities of 5 per package.

Key Product Differences

Variants within the SGT-Half-Bridge-Uniaxial series differ by nominal resistance, grid pattern dimensions, termination style, and temperature compensation material. The model number follows the format SGT-<PATTERN>-<RESISTANCE>-TY<CODE>.

Nominal Resistance

350 Ω: Standard resistance for most models in both 9.2 mm and 14.3 mm carrier sizes.
1,000 Ω: Available on the SGT-1LH pattern with a larger grid B dimension (4.8 mm / 0.198 inch) compared to the 350 Ω version of the same pattern.
