Mechanical 3D Crackmeter
The mechanical 3D crackmeter is used with a dial indicator to monitor movement at joints and cracks. Typical applications include:
- Monitoring construction joints to evaluate structural performance.
- Monitoring cracks in structures near active construction sites.
- Monitoring movement of rock masses in natural rock formations.
Readings are obtained by inserting a the probe of a dial indicator through the access holes to contact opposite component. Take three sets of XYZ readings to ensure that you have a good baseline for comparison. Compare subsequent readings to the baseline. Changes indicate that movement has occurred.
Easy Installation: Installation requires only two drill holes. Welding plates are also available.
Simple Operation: The crackmeter is read manually with a digital micrometer.
