Uses of Vibrating Wire Crackmeter in Concrete Structures

Monitoring and measuring of movements across surface cracks and joints in concrete structures or rock is done by the Vibrating Wire crackmeter. Monitoring applications include   brick and stone buildings, bridges and dams, construction joints, pipelines and joints in concrete and rocks. Made of high quality steel, the sensor provides accurate and reliable readings for long term monitoring.  

It is fully waterproof and is ideal for both manual and remote monitoring. The sensor is fitted across a joint or crack and keeps a track of any movements by detecting changes in tension in the vibrating wire.  It is connected with a thermistor to monitor the temperature.

Deformation of rock or soil masses is detected by the convergence meter.  The device detects and measures contraction or elongation between two fixed anchor points that are set up in the mass. Connecting rods from one anchor leads to the transducer assembly that is placed at the second anchor point. The transducer records the changes in distance between the two anchors.

Three way movements at block joints and cracks are monitored by the vibrating wire triaxial joint meter. It has a 3D mounting system that comprises of two arms and two groutable anchors and three displaceable transducers to monitor the temperature. The instrument is waterproof and is suitable for both manual and remote monitoring. It gives robust and accurate readings and comes with a over-voltage surge arrestor for protection against electrical damage.
