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.
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.
