Extensometer rock bolt

The extensometer rock bolt is a combination of an anchor and a measuring instrument. The instrument provides the opportunity for better determination of suitable anchoring lengths for rock reinforcement. It is extremely cost-effective for the following reasons.

• The instrument can be used in the same borehole as the rock reinforcements
• The instrument replaces normal rock reinforcement
• The instrument is very easy to use since it is read off mechanically

 

In the case of fully-automatic measuring, measurement data can be collected automatically by our data loggers and presented online on the Internet in our web system, where alarms are received and access is given to measurement values that are presented in a clear and effective way.
