Vibration Sensor

Sensor that records ground or structural vibrations in three directions, useful for monitoring construction impact. It also helps detect early signs of structural distress or instability.

Vibrating Wire Horizontal Profile Gauge

Sensor measuring horizontal displacement within soil or fill materials. Commonly used for monitoring embankments and ground stability. Data helps evaluate settlement patterns over time.

Tape Extensometer / Distance Gauge

Simple manual tool to measure changes in distance between fixed anchor points. Often applied in tunnels, slopes, or excavation sites. Reliable for periodic manual measurement programs.

Vibrating Wire Load Cell

Device that measures loads in anchors, struts, or supports using changes in vibrating wire frequency. Ensures safety by tracking applied and transferred forces over time.

Instrument Types and Subtypes

Each instrument type and subtype is defined by its applications, the measurements it provides, monitoring capabilities, and data range. This classification ensures accurate selection for project needs and reliable performance in geotechnical monitoring.

Gas Leakage Sensors

Gas leakage sensors detect the presence of hazardous gases in the environment or confined spaces. They provide early warning of leaks, ensuring safety in tunnels, underground works, and construction sites by preventing accidents and health risks.

Convergence Bolt

Special bolt installed in tunnels to track changes in rock displacement and convergence. Provides early warning of ground movement. Easy to install and cost-effective for long-term monitoring.

Vibrating Wire Pressure Cell

Instrument used to measure soil or rock pressure against retaining structures or tunnel linings. Helps assess load distribution and safety. Often applied in tunnels, retaining walls, and dams.
