Strain Gage Extensometers
The models in this series of extensometer can be used to measure either longitudinal or transverse strain, or can be used in combination for determining ‘r’-value and Poisson’s ratio. Operation is simple with strain gage resistance changes providing the means for determining the travel of knife edges on the specimen.
Key advantages of using strain gage type extensometers are as follows:
- Can be left on specimen through failure
- Lightweight to minimize any influence on the test
- Low operating force
- Rugged construction to withstand rigors of operation.
