Crackmeters & Jointmeters
- Sisgeo Crackmeters & Jointmeters to monitor movement across surface cracks and joints in concrete structures or rock.
- The instrument assembly includes sensor housing and target, both parts are equipped with screw anchors.
- Typically the anchors are bolted on the opposite sides of the joint (crack).
- The displacement transducer housed in the sensor body is positioned across the joint/crack enabling to measure the changes in the distance between the anchors.
- CRID is an integrated automatic system for fissure monitoring of building and monuments reducing the visual impact.
