Combined sensor for vibration and dynamic pore pressure

Geometrik’s combined vibration sensor is designed to meet acceleration in three directions, the dynamic pore pressure and the vertical settlement movement.

 

The sensor was developed in order to measure the impact on existing land of nearby blasting operations in a large infrastructure project. The work was to be conducted in the vicinity of several sensitive buildings and facilities. During the trials, test blasting was conducted, whereby the sensor registered vibrations, dynamic pore pressure and settlements. The results were of great value to the project that was to determine the preconditions for the future blasting operations.

 

The sensor can be adapted to suit different measurement directions, measuring ranges and environments. 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.
