Supported Applications
The Omega SGD Series Precision Strain Gages are designed for static and dynamic strain measurement applications. These linear pattern gages measure strain in a single direction, indicated by an arrow on the pattern showing the principal stress direction. They are commonly used in experimental stress analysis.
- Stress concentration or high gradient areas (miniature linear patterns)
- Inhomogeneous materials (extra-long grid options available)
Operating Conditions & Performance
The measuring grid is formed by etching constantan foil and sealed in a polyimide film carrier. The gages are described as very flexible, mechanically strong, with a small bending radius, operating over a broad temperature range.
Maximum permitted bridge energizing voltage (Vrms) varies by model configuration:
- Ranges from 2.5 Vrms to 75 Vrms depending on gage pattern and resistance
Dimensions Key
The specification sheet defines the following dimension parameters for each model:
- A: Active gage length
- B: Active gage width
- C: Matrix (carrier) length
- D: Matrix (carrier) width
Configuration Options
The series offers a wide range of configurations defined by the model number guide format: SGD-<GAGE_PATTERN>-<RESISTANCE>-<TERMINATION>-<TEMP_COMP>.
Gage Patterns and Sizes
- Miniature linear patterns for stress concentration or high gradient areas
- Wide or narrow grid patterns
- Small, medium, or large pattern sizes (e.g., 1.5 mm to 150 mm active lengths)
Nominal Resistance Options
The series supports the following nominal resistance values as listed in the specification tables:
- 120 Ω
- 240 Ω (specific models, e.g., SGD-150/240-LY40)
- 350 Ω
- 1000 Ω
Termination Types
Gages are available with two electrical connection methods:
- Ribbon Leads: Standard termination for many models.
- Solder Pads: Available on specific patterns, often paired with Bondable Terminal Pads (BTP) options such as BTP-1 through BTP-6 depending on the model size and pattern.
Temperature Compensation
The series offers temperature compensation for:
- Steel (ST)
- Aluminum (AL)
- Uncompensated (UNC): Available on specific extra-long models such as SGD-30/120-LY40 and SGD-50/120-LY40.
Special Service Options
The series includes "Extra-Long For Inhomogeneous Material" configurations with extended active lengths (e.g., 25.00 mm, 30.00 mm, 50.00 mm, and 150.00 mm). Custom-designed strain gages are available without minimum quantities upon consultation with engineering.
Key Product Differences
Variants within the SGD Series differ primarily by active grid dimensions (A x B), carrier size (C x D), nominal resistance, and termination style. The model number explicitly identifies these parameters; for example, a "LY11" suffix indicates 120 Ω with Ribbon Leads and Steel compensation, while "LY43" typically denotes Solder Pads with Aluminum compensation.
Clear alignment marks are included on the gage pattern to assist in installation. The carrier or matrix material may be trimmed in the field on all sides within 0.25 mm of the foil grid without affecting strain gage performance.

Pretty straightforward strain guahe
Purchased to use for a power meter on a bicycle. They are working well now that I have them hooked up, but getting them on properly was a bit of work. I have only done this once before but last time I remember it being easier. I couldn't get the pads to wet with solder for a long time and had the pads rip off on a few by accidentally pulling on the cables (lightly) once they were hooked up. Probably my own fault, but I did barely touch them. I put on a new pair and smothered them in superglue, they are stellar now.

They work, but with some installation issues
These strain gauges work reasonably well, but with lower mechanical gain than some other brands. Their solder pads are actually quite difficult to solder to, and multiple calls to their technical help line went unanswered.

Good quality gauges, but fragile
I have gotten reliable, great quality readings from these gauges, but they are very fragile and finicky to apply. There is an expectedly long learning curve to apply the gauge to the specimen. The soldering process is unexpectedly finicky, though. I've had a lot of difficulty getting solder to adhere. I need to pour a lot of heat into them, which is unnerving. I have also had a tab or two come loose and break off while attempting to attach wires. Expensive mistakes... would be great if these were more robust.

Timely Delivery, but Room for Improvement
The strain gauges arrived earlier than expected, which was impressive and greatly appreciated. The packaging was mostly secure, but one group was fastened with a rubber band that slightly compressed them. Thankfully, there was no damage, but more attention to this detail would ensure a flawless experience next time.

Efficient delivery and high product quality
The product of strain gauges were delivered very efficiently such that we were able to eliminate any possible delay for our important testing. In the meantime, the quality of Omega strain gauges is the best of the peer products from other manufacturers.

How much required voltage is needed to get the strain gauges to function/record data properly?
Joejoe2768 Thank you for contacting Omega Engineering, the max V rms will be listed in the spec sheet corresponding to each strain gauge based on grid length and width.

Is it $52 per sensor or $52 for a pack of 10?
JoeJj Thank you for contacting Omega Engineering, this price will be for a pack of 10

What is the recommended Wheatstone bridge configuration that you would recommend for these particular strain gauges and preferably one that is compatible with multiple sensors at once? Thank you.
These gauges can be used in a 1/4,1/2 of full bridge configuration. Full bridge best due to it having the highest sensitivity.

Good Day, I have reviewed your datasheets but I am not able to find detailed information about the strain gauges you offer. What is the maximum deflection of your gauges? What is the relationship with the change in resistance? Thank you.
Thank you for contacting Omega with your question. Specifications for the strain gages can be found in the Technical Reference section on our website under the heading “Pressure, Strain and Force Related”. Here is a link to the site for the spec sheet

is this a 350 gage or 120? Description says one thing and the item number is: SGD-3/350-LY11
JBOB, the SGD-3/350-LY11 stands for 3 mm grid, the 350 stands for 350 ohm and the LY stands for Linear. The description is incorrectly marked as 120 ohm. Please go with description on the spec sheet

The description says these gauges have a "broad temperature range". Are there some materials (like Aluminum or steel) that they are specifically compensated to,or are these essentially non-compensated gauges?
If you look at Data Sheet pdf for the SGD gages you will that there are 3 variation of Temperature Compensation. AL for Aluminum. ST for Steel/Stainless Steel. UNC for Uncompensated.
