Rock stress cell for boreholes

The rock stress cell for boreholes consists of three pressure cells mounted with a 120° torsion displacement. The sensor can measure stress in three axes but can also measure the direction of the axes because the sensor can be oriented together with the related rod system. 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.
