TMB series built-in strain gages for testing of the pre-strained concrete.
These gages are used to determine and control the mechanical stress of concrete. Material of the sensitive grid: Constantan or Karma alloy. The length of the sensitive grid is 80 mm or 100 mm. TMB series strained gauges are thermally compensated for concrete.
