The three-dimensional coordinates of arbitrarily arranged displacement points are determined through the optical trigonometric measurement of targets in repeated measurement periods in an absolute reference system. This is realized by a number of reference points that are recorded and assumed to be constant. The location of the measuring instrument is selected according to the best possible visibility conditions of the targets and reference points according to the principle of free stationing.
The recorded measurement data is transferred to an evaluation computer and processed with our EUPALINOS software. The results, relative shifts in relation to a zero measurement, are visualized in diagram form. A multitude of different display options helps the geotechnical engineer interpret these results. This method allows the detection of displacements depending on the measurement configuration with accuracies from < 1 mm to a few millimeters.
The measurement data can also be automatically transferred to KRONOS and linked to data from other sensors.
KRONOS enables a wide range of graphical and numerical evaluations, data filtering and analysis as well as alarms and automatic PDF reporting.
