ELECTRICAL AND VIBRATING WIRE CRACKMETERS
Crackmeters are intended to monitor movements across surface joints or cracks, mainly in concrete structures or rocks. Crackmeter consists of a vibrating wire or potentiometer displacement transducer housed in a stainless steel telescopic body with two anchoring points. These anchors have self-lubrificating ball joints allowing lateral movements up to ±10° in the orthogonal planes (Y - Z axis) not influencing the operation of the jointmeter.
? Cracks on concrete structures or rock ? Structural joints like in concrete dams ? Displacements on pile bearing ? Monitoring of rock faults
? 3-D mounting kit available for triaxial displacement monitoring ? Ball joints allow small lateral movement ? Suitable for long term monitoring
