These measuring devices are designed to monitor movement across surface cracks and joints in rock, soil and building structures.
Crack measurements are used in a number of infrastructure and mining projects to monitor possible cracks in structures caused by nearby excavation or tunneling, for example. Typical applications include tunnel and shaft linings, buildings, bridges and dams.
The measuring device is a uniaxial mechanical crackmeter. The uniaxial crackmeter is installed by mounting the two anchors with ball joints on either side of the crack/joint, and then attaching the jointmeter body to ball joints. The central processing unit of this device transfers the measurement data automatically to FinMeas Online which provides easy access to up-to-date measurement data from any device.
