Tunnel Monitoring
Convergence measurement on the tunnel segment or support shell, with multiple sensors along the tunnel axis to capture the complete deformation profile. Hourly measurements with no maintenance required.
Three spatial axes with a repeatability of ±50 µm. External battery box for long measurement intervals and hard-to-reach locations. Made in Austria.
Convergence measurement on the tunnel segment or support shell, with multiple sensors along the tunnel axis to capture the complete deformation profile. Hourly measurements with no maintenance required.
During multi-year renovations of historic structures and buildings designated as cultural heritage sites, the XT 3D sensor provides a continuous data stream without requiring on-site maintenance.
Two screws per component; activated by connecting the battery cable. No special tools required; no need for on-site technical personnel.
All measurement data in a single dashboard. CSV export for structural engineers and reports, API integration for third-party sensors, and multi-tenant support for complex projects.
An external battery box provides power for hourly measurements throughout the entire project duration. No maintenance is required on the sensor.
Transmission via LTE-M and Wi-Fi directly to the SuessCo Datahub.
If a threshold is exceeded, our system automatically sends an email or text message notification.

Wireless 3D measurement of concrete segments in tunnel construction.
“Following a tunnel fire, the 3D sensors from SuessCo Sensors FlexCo were deployed to monitor the affected tunnel arch segments. Continuous monitoring made it possible to maintain temporary operations until final repairs could be completed. As part of the safety management plan, alarm thresholds were defined, and a specific group of people would have been notified via email and SMS if the alarm threshold was reached. The system stands out for its precise measurements and the wireless remote transmission of data to a portal that experts can access at any time without disrupting operations.”

“Our collaboration with SuessCo Sensors has always been professional and solution-oriented. For expert assessments, the continuous measurement data from the SuessCo sensors is a major advantage, as changes can be objectively documented and reliably evaluated." "With the XT 3D sensors, we receive precise and stable measurement data wirelessly in three dimensions. This enables reliable remote monitoring of sensitive tunnel areas and significantly reduces our on-site workload."

"SuessCo's sensors have proven to be extremely precise and easy to install. What is particularly impressive is that they withstood the extreme conditions of the Swedish winter without any problems. Our collaboration with SuessCo has always been reliable and professional."
Paul Collins
Sales Manager, GEOFIX Sweden
"With the SuessCo 6D sensors, we always have up-to-date measurements available. This naturally saves us money and improves quality."

The XT 3D sensor uses an external battery pack instead of a built-in battery. This allows it to operate for ten years with hourly measurements. The standard 3D sensor lasts ten years with daily measurements. In addition, the XT’s housing is more compact because the battery is external.
