It detects and reports vibration loads caused by slope displacement, falling rocks, debris flows, earthquakes, etc.
The wireless sensor network system sNet-920 is a system that monitors tilt displacement and shock/vibration loads using the specific low-power wireless 920MHz band. It detects and reports how much shock and vibration have been applied to structures due to minor tilt displacements or events such as falling rocks, landslides, and earthquakes. By using ad-hoc multi-hop communication, it enables centralized monitoring by widely distributing sensor nodes. It provides real-time notifications when displacements (tilt angles) or shock vibrations exceed set values. **Features** - Tilt displacement shock/vibration load monitoring system - Long-distance communication via 920MHz band wireless - Long-term operation with built-in battery - Centralized monitoring and measurement from multiple points through multi-hop communication - Compatible with extensometers, crack displacement gauges, and pore water pressure gauges For more details, please contact us or download the catalog.
