TSV Takuwa Vibration Sensor for Debris Flow Detection

Description

TSV Takuwa Vibration Sensor with acceleration sensor is to detect the vibration caused by debris flow and volcanic mud flow. It is designed to provide the alert when the vibration detected by acceleration sensor is greater than a certain definite value (arbitrarily-settable alert level) and continued during a certain definite time (arbitrarily-settable continuous detection time)

In addition, alarm output can be set up in 5 (five) steps and it allows an estimate of scale of debris flow in real-time at great distances by transmitting individual alarm output. 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.
