Product Description

 

Velocity Geophone Sensor Seismic Sensor For Earthquake And Blasting Vibration



1. Earthquake monitoring: Velocity seismic sensors are widely used in seismic networks to monitor and record seismic waves in real time, so as to facilitate the analysis of seismic activity and its impact.
2. Blasting Monitoring: In mining and building construction, monitoring the vibration caused by blasting to ensure construction safety and prevent damage to the surrounding environment.
3. Structural health monitoring: for monitoring the vibration impact on large infrastructure (e.g. bridges, tunnels, etc.) during earthquakes or blasting to assess their safety.
4. Environmental protection: to assess the impact of engineering activities on the surrounding ecological environment through vibration monitoring.
