Highlights
- Supports up to 4 vibrating wire and/or thermistor instruments from any manufacturer
- Perfect system for monitoring surface piezometers for open-pit mines
- Data acquisition is completely wireless and battery-powered
- Standard wireless range underground up to 150m+, on surface over 600m!
- Standard battery pack lasts about 3 years, with options for a 10 year battery pack or external power (solar)
- Purpose built wireless mesh network for Geotechnical Instrumentation and Monitoring
- Fast installation with no need for skilled labour to run wires or install infrastructure
- Unlimited scalability – just add more wireless nodes to extend the system
- 900MHz mesh is an excellent choice for underground mining applications – signals go around corners very well
- Integrates seamlessly with the MDT-RTU
- Also acts as a standard infrastructure/repeater node for the network
