Tilt Sensors / Nano Triaxial Tilt Sensor Node Range

The Nano range is different because it provides IoT intelligence, responsiveness, and delivers engineering-grade precision. Key features include:

• Resolution of 0.0001° (0.00175 mm/m)
• Repeatability as low as ±0.0005° (±0.0087 mm/m)
• Exceptionally stable triaxial MEMS sensing
• Extremely low noise performance
• Maximum reporting frequency of 2 seconds
• Operates in any orientation
• Compatible with InfraGuard – responsive critical asset protection
• 20+ years of Senceive refinement in tilt technology

These capabilities allow the Nano to capture subtle angular changes reliably, even in harsh environments.

The Nano tilt node is ideal for projects requiring high-frequency, high-precision movement data, including:

• Tunnel deformation and convergence
• Slope and embankment stability
• Rail trackbed geometry monitoring
• Bridge, building, dam and retaining wall movement
• Mining and underground infrastructure
• Any infrastructure where small changes need continuous monitoring

Its two-second reporting capability makes it especially suited for applications involving high-value or at-risk infrastructure.

Yes. the NanoMacro Tilt Sensor includes a sleep mode that helps preserve battery life without removing the sensor or disconnecting it from the project network. This is useful for projects with staged monitoring phases.

The NanoMacro has an exceptional 12–15 year battery life at 30 minute reporting intervals, including while acting as a relay in the FlatMesh mesh network. This makes it ideal for long-term monitoring programmes where accessing equipment is difficult or costly.

Yes. The Nano is a highly robust device designed for extreme conditions with:

• IP67 / IP68 / IP69K waterproof rating
• Operating temperature range from –40°C to +85°C
• Shock-resistant, low-profile enclosure
• Versatile mounting options for steel, concrete, timber, soil and more

This durability makes it suitable for railways, tunnels, mines, marine environments and exposed structures below and above ground.

• Tested to conformity with all the essential requirements of the Radio Equipment Directive 2014/53/EU and RoHS Directive 2011/65/EU.
• FCC Grant of Equipment Authorization.
• Transit Drop Tested to MIL-STD-810G CN1 method 516.7.
• Vibration and Shock tested to EN 50125-3 on rail sleepers/ties.

Senceive Tilt Sensors, including the Nano range are widely used by major infrastructure owners, contractors, and surveying companies around the world. For example, UK rail infrastructure company Network Rail has used Senceive for rail track, structural and slope monitoring.  They have installed over 20,000 sensors alone for slope monitoring adjacent to rail tracks.  Other big rail users include Deutsche Bahn, SNCF, ProRail and all the North American Class 1 rail operators.

Senceive technology is compatible with international standards and regulatory requirements.

The Nano supports multiple mount types to suit different structures and materials:

• Magnetic mounts — ideal for quick fixing to steel or cast iron structure
• Two-part mounts — for gluing or screwing to rail track sleepers/ties 
• Swivel mount — perfect for vertical surfaces such as walls, columns, abutments
• Stake mounts — for soil or catchfences (available in 1250 mm, 1500 mm and 1750 mm kits)
• Custom clamping and adhesive solutions.

These mounting options make it easy for users to instal sensor nodes quickly and flexibly in any environment.

Yes. Senceive Nano Triaxial Tilt Sensor Nodes can detect subtle rotational movements in the ground, making them ideal for monitoring slope stability and embankments. They are often installed on stakes/poles. When combined with other sensors in a FlatMesh network, such as piezometers, IPI’s and extensometers they offer a comprehensive picture of ground behaviour.

Senceive Nano Triaxial Tilt Sensors are also used for slope monitoring where users are concerned about landslides, rockfall and drainage problems. 

Yes. The Nano tilt sensors include an integrated temperature sensor, enabling additional environmental insight and supporting temperature-related analysis in monitoring projects.

The Nano features Near Field Communication (NFC™), allowing users to interact with the node on-site via a paired NFC reader.

Benefits include:

• Quick configuration and identification
• On-the-spot checks without opening the enclosure
• Faster commissioning and troubleshooting

High vibration environments, such as railway track, present challenges for highly sensitive tilt sensors. You want to know if your assets are moving, but not every time a train or a truck passes by.  The High-G NanoMacro Tilt Sensor provides a solution. It effectively filters out high magnitude dynamic events, allowing you to assess long-term trends.

Yes. The Nano can operate within a mixed-sensor Senceive network, and Senceive systems support integration with third-party instruments such as:

• In-place inclinometers (IPIs)
• Piezometers
• Strain gauges
• Displacement sensors
• Vibrating-wire sensors
• Compatible geotechnical instruments from other suppliers and our sister company Sisgeo.

All sensors can transmit through a single gateway and be visualised together in WebMonitor™.

Data from our tilt sensor nodes is transmitted wirelessly to a Senceive Gateway, and then to WebMonitor — our platform for data visualisation, trend analysis, alerts, and integration with other systems.
