Crack Meter
Crack Meters are employed in multiple geotechnical construction applications to monitor movement in structures along surface cracks or construction joints. Crack Meters are primarily used during the construction of mass concrete structures such as dams, bridges, and retaining walls.

Descriptions
When installed, Crack Meters record and monitor any structural changes caused by geotechnical activity, allowing for ongoing oversight of structural integrity. Crack Meters consist of two mounting anchors, each of which is secured to either side of the joint or crack. Crack Meters can be anchored to either side of a crack or joint to measure displacement. In both cases, the anchors are connected with a vibrating wire displacement transducer.
If movement occurs within the structure causing the distance between the anchors on either side of the joint or crack to change, this change of distance will accurately be measured by the vibrating wire transducer. Crack Meters can also be used to trigger an alarm if structural movement exceeds a pre-set maximum displacement.
An accurate history of this movement will be recorded using an RST Vibrating Wire Readout or Data Logger.
