Description

Vibrating Wire Crack Meter for Continuous Structural Monitoring

Geosense VWCM-4000 is a vibrating wire crack meter designed for continuous,
real-time monitoring of movement across surface cracks and joints in concrete,
masonry, rock, and structural elements.

The sensor consists of a robust outer body and a free-sliding internal rod connected
to a vibrating wire element, providing highly stable and reliable long-term
displacement measurements.

• Geotechnical and civil engineering projects

infrascan Integration

Geosense VWCM-4000 can be fully integrated into InfraScan monitoring systems,
providing real-time visualization, trend analysis, and automated alerts
through the monitoring dashboard.

Sensor selection and installation configuration are defined based on crack
behavior, required measurement range, and environmental conditions.
