Instrumented Rockbolts (VW) - Model 4910

The Model 4910 Instrumented Rockbolt comprises a vibrating wire strain gage located inside a short length of standard threaded rockbolt or rebar. This short length is then connected via a coupling to a longer length of the same bolt material. The instrumented rockbolt is installed in the same manner as conventional rockbolts, making sure that the strain gage remains located within the loaded part of the rockbolt.
