Description

Multi-Axis Digital Sensor for Real-Time Crack and Structural Displacement Monitoring

Sisgeo DEX-S is a digital extensometer-based sensor designed for continuous,
real-time monitoring of crack opening, relative displacement, and structural movement
in buildings and infrastructure.

Unlike simple linear crackmeters, the DEX-S allows measurement of multi-directional
displacement and is suitable for applications where crack behavior includes opening,
shear, or combined movements.

Measured Parameters

• Crack opening (linear displacement)
• Relative structural displacement
• Multi-axis movement (depending on configuration)

Typical Measurement Range

• ±10 mm
• ±25 mm
• ±50 mm
• Custom configurations available

Accuracy & Performance

• High-resolution digital measurement
• Excellent long-term stability
• Suitable for permanent monitoring installations

Data Output & Integration

• RS485 / Modbus digital output
• Direct integration with dataloggers and IoT gateways
• Real-time data streaming to monitoring dashboards
• Ideal for continuous and automated monitoring systems

Typical Applications

• Structural crack monitoring in concrete and masonry
• Monitoring of combined crack opening and shear movement
• Buildings, tunnels, bridges, and retaining structures
• Urban and infrastructure monitoring projects

i

Sisgeo DEX-S sensors are fully compatible with InfraScan monitoring systems and can be
integrated into real-time dashboards for displacement visualization, trend analysis,
and automated alerts.

Sensor configuration and installation geometry are selected based on structural behavior
and monitoring objectives.
