CSignum has announced its EM-2S through-ground wireless communications solution, extending the company’s technology portfolio to geotechnical, structural and infrastructure monitoring applications.
The EM-2S enables bidirectional data communications through soil, rock, concrete, water, and mixed-media environments, providing access to measurements from buried and embedded instrumentation.
“Through-ground wireless communications open new possibilities for how engineers monitor buried infrastructure and embedded instrumentation,” said John Nicholls, CSignum’s CEO. “By extending our EMFS technology into soil, rock and concrete, we can make critical sensor data accessible in locations where conventional communications approaches are difficult to deploy.”
The unit itself combines wireless communications, data logging, edge processing and an internal battery in a compact, resin-filled enclosure.
Applications
- Ground movement: Monitors lateral displacement, settlement, foundation movement, structural rotation and deformation, through integration with inclinometers, tiltmeters, extensometers, settlement sensors and crack meters.
- Groundwater: Tracks pore water pressure and hydrological conditions affecting foundations, embankments and soil stability, using piezometers, level sensors and subsurface instrumentation.
- Structural stress: Communicates with strain gauges, earth pressure cells and load cells to measure structural loading and deformation in foundations, retaining walls, ground anchors and tunnels.
- Tunneling: Tracks tunnel convergence, retaining wall deflection, ground displacement, groundwater pressure and changing soil or rock conditions.
- Vibration: Monitors construction-related and transportation-related ground motion, subject to instrument data-rate requirements.
- Mixed-media infrastructure: Tracks equipment beneath roads, airport runways, dams, embankments and buried pipelines.
