Supported Applications
The Omega SGD Dual Parallel Grid series consists of precision strain gauges designed for monitoring bending strain. These dual-linear pattern sensors are engineered to measure deformation in applications requiring the detection of flexural stress.
Operating Conditions & Performance
Performance is defined by specific grid patterns and maximum permitted bridge energizing voltages (Vrms) that vary by model configuration. The series supports nominal resistances of 350 Ω and 1000 Ω. Maximum voltage ratings range from 6.5 Vrms to 40 Vrms depending on the gage pattern, resistance value, and termination type selected.
Configuration Options
The series offers a configurable envelope across grid sizes, electrical connections, temperature compensation materials, and physical dimensions.
- Gage Patterns: Available in multiple configurations identified by pattern codes (e.g., 5.5 mm, 6 mm, 7.4 mm, 11.8 mm actual size representations).
- Nominal Resistance: Options include 350 Ω and 1000 Ω.
- Termination Types: Models are offered with Ribbon Leads or Solder Pads for electrical connection.
- Temperature Compensation Materials: Configurable for Steel (ST) or Aluminum (AL).
- Packaging: Supplied in packages of 5 units per model number.
Key Product Differences
Variants within the SGD-DUAL-GRID series are distinguished by their gage pattern, nominal resistance, termination method, and temperature compensation material. The model numbering convention follows the format: SGD-<GAGE PATTERN>-<NOMINAL RESISTANCE>-DY<TERMINATION>-<TEMP COMP>. For example, SGD-2/350-DY43 denotes a 350 Ω strain gage with Solder Pads and Aluminum temperature compensation. Physical dimensions for Grid A, Grid B, Carrier C, and Carrier D vary by the specific pattern selected.

Following up from the last question, does the m in me/C stand for micro or milli?
Hello, you are referencing the NI article, typically me should stand for microstrain, for further questions feel free to contact NI directly. https://www.ni.com/en/contact-us.html

I am curious on how the change in temperature will affect the resistance and reading of this sensor. Do you have any information on this?
Hello, I am quoting NI here: Strain gage manufacturers attempt to minimize sensitivity to temperature by processing the gage material to compensate for the thermal expansion of the specimen material for which the gage is intended. While compensated gages reduce the thermal sensitivity, they do not totally remove it. A residual error on the order of 10 me/°C is still possible when you use a temperature compensating gage. Therefore, additional temperature compensation is sometimes necessary.

Note that we do not have information on the polynomial coefficients of the temperature curve.
