Suitable for compressive changes of rock-bed and enables measurement of upheaval.
The BRD-AT series rock-bed compression displacement transducers are designed to measure compressive changes of rock-bed. They detect relative displacement between the ground surface and the anchor fixed to the bottom of a boring. A temperature measuring function enables simultaneous measurement of displacement and temperature. Zero balance adjustment at the time of installation enables measurement of upheaval, and thus they can be used for rock-bed grout management.
