Cảm biến đo biến dạng trong cốt thép Geokon 4151

The Model 4151 is a modification of the Model 4150 strain gage in which the spot-weldable tabs have been replaced by pins welded to the end blocks and designed to be grouted into two short holes drilled into the material under test. Special versions of the Model 4151 are available with extended ranges. 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.
