BM-X Wireless tiltmeter node
Robust biaxial wireless tiltmeter for geotechnical monitoring, designed for harsh environments and large-scale wireless mesh networks.
Key features
- ±15° biaxial MEMS inclinometer
- IP67 housing for outdoor use
- Long-range mesh networking (up to 5km)
- Ultra-low power with up to 18 months battery life
- AES128 encrypted wireless data transmission
- Supports up to 50 nodes in one network
Performance highlights
The BM-X Wireless Tiltmeter Node offers precise biaxial tilt measurements using a Sisgeo self-compensated MEMS inclinometer. It achieves ±0.003° accuracy in lower ranges and provides a resolution of 0.0001°, making it ideal for applications requiring high sensitivity.
Usage conditions
With an operating temperature of -40°C to +80°C and a rugged die-cast aluminium IP67 enclosure, the BM-X is built for long-term outdoor use, including construction sites, tunnels, and underground deployments.
Possible applications
- Structural health monitoring
- Tunnel and dam deformation monitoring
- Geotechnical slope stability assessments
- Rail or bridge tilt tracking
- Remote or underground infrastructure monitoring
Advantages of choosing this product
The BM-X enables scalable, low-maintenance monitoring through its long-range wireless mesh capabilities (up to 50 nodes and 5km LoS range). It offers encrypted data transmission, Android app support, and robust mounting options for quick deployment in complex environments.
Other important features
- ISM radio band (863-870 / 902-928 MHz)
- Multiple mounting options (horizontal/vertical/rail)
- Android app for configuration and monitoring
- Internal temperature and barometric sensors
- USB and IDC10 ports for diagnostics & firmware updates
