Sabo Sensors (for debris flow and landslide)
Sediment disasters occurred by heavy rain and earthquake could inflict a serious damage to human life and property.
For mitigate or prevent sediment disaster, it is necessary to monitoring a sediment movement by using detecting sensors.
We have a lineup of various sensors for monitoring of debris flow, landslide, and landslide-dam
Its delivery records are in Japan and Asian countries.
Wire Sensor -Optical Fiber type (For debris flow detection)
"Optical fiber type wire sensor" detects a debris flow directly by cutting the optical fiber which is strung cross section of torrent.
Also in transmission line from sensor to control box, it is available the optical fiber.
Particuralry, it is suitable for the torrent where is occured many noise or thunder.
Features
- ・Optical fiber is used for both transmission line and detection line
- ・Easy Installation and Maintenance
- ・Secure detection by simple method
- ・Low cost
Available sites
- ・Debris flow detection at torrent
- ・Landslide detection
