Vibration sensor is for detecting a debris flow indirectly and repeatedly by measuring a ground vibration. Usually sensor is buried in ground near the torrent. Detected signal can be output to the warning siren device for evacuation information. In addition, it is possible to estimate discharge of debris flow by amplitude of vibration.
Features
- ・ Non-contact measurement with Debris Flow and Unbreakable, Continuous Detection is Possible
- ・ Can Estimate a Flow Discharge by Amplitude of Ground Vibration
-
- ・ Easy Installation and Maintenance
Available sites
- ・Debris flow detection at torrent
