RST’s Crack Meters are designed to measure movement across surface cracks and joints. They are easily installed by grouting, bolting or bonding the two threaded anchors (with ball joints) or other mounts, on either side of the crack/joint, and then reattaching the anchors to the sensor.
- Monitor crack separation or convergence, in concrete structures.
- Monitor joints for movement caused by nearby geotechnical activity.
- Alarm triggering when separation or convergence of two reference points reach a preset critical rate or value – requires use of data logger and RST’s GeoViewer Software.
