It is a high-precision seismic sensor designed to measure strong ground motions during earthquakes and other dynamic events. Unlike traditional accelerometers, the force balance (or force-balance accelerometer, FBA) technology provides superior accuracy, low noise, and a wide dynamic range, making it ideal for critical infrastructure monitoring.
Applications
Building Earthquake Monitoring
Measures real-time seismic forces on high-rise buildings, hospitals, and critical infrastructure.
Helps in post-earthquake damage assessment and retrofitting decisions.
Used in seismic early warning systems to trigger emergency protocols.
Structural Health Monitoring (SHM)
Monitors dynamic structural responses in bridges, dams, and towers.
Detects fatigue, cracks, and deformations due to vibrations.
Supports predictive maintenance by analyzing long-term vibration trends.
Ground Vibration Monitoring (Accelerograph)
Records strong ground motions for earthquake engineering studies.
Used in seismic hazard mapping and microzonation studies.
Essential for nuclear plants, pipelines, and tunnels to ensure stability.
