Extended Range Strain Gage

Model 4151

Special versions (Model 4151) of the Model 4100 VW Strain Gage are now available with an extended range (5,000 or 10,000 strain).

These gages are particularly useful for measurements in high strain regimes such as on plastic pipes or piles and on fiberglass structural members and rebars.

A unique design allows these gages to be manufactured without increasing their overall length, making them particularly suitable where space and or access is limited.

The accuracy of these gages is ±5.0% FS using a calibration batch factor or 0.2% FS with individual calibrations.
