BR-BT
Stress Transducers Built to order
2 to 10MPa
Enables measure concrete stress directly as stress and not via strain
A temperature measuring function enable them to measure stress and temperature simultaneously.
Features
- Theoretically backed performance of direct concrete stress measurement with no conversion from a detected strain quantity.
- Receive minimal effects of creep and changing elastic modulus of concrete. and there by ensure accurate stress measurement.
- Also usable for stress measurement of the natural ground by installing at the rear of a tunnel lining.
