BS-25AT,25BT
Strain Transducers
±500 & ±1000 μm/m
BS-25AT,25BT
These transducers are intended for measurement of the strain occurring inside concrete with comparatively large aggregates.
Strain transducers BS-25AT/BS-25BT are intended for measurement of the strain occurring inside concrete with comparatively large aggregates. Since a temperature measuring function is provided, these transducers can simultaneously measure strain and temperature.
Features
- The linear expansion coefficient is approximated to that of concrete to minimize temperature effects, thereby enabling measurement of external force-initiated strain and the strain corresponding to temperature stress.
- Minimal damage against embedment vibrator and endures vibration initiated by the RCD method.
