Crack Monitoring
For cracks and joints subject to three-dimensional movement, the 3D sensor measures displacement along all spatial axes. A complete movement history for expert reports and damage assessments.
Absolute position changes in the X, Y, and Z axes with a repeatability of ±50 µm. Wireless transmission via LTE-M and Wi-Fi. Made in Austria.
For cracks and joints subject to three-dimensional movement, the 3D sensor measures displacement along all spatial axes. A complete movement history for expert reports and damage assessments.
The 3D sensor is the ideal solution for measuring settlement at the abutment or displacements in the structure that do not involve rotation.
Two screws per component; activated by a magnet. No special tools required; no need for on-site technical staff.
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.
10-year battery life with daily measurements. No need to replace the battery during the project period.
Data is transmitted directly to the data hub via LTE-M and Wi-Fi. No external cabling is required on the building.
If a threshold is exceeded, our system automatically sends an email notification.

Real-time structural monitoring following a tunnel fire to enable rapid reopening during ongoing restoration work.
High-precision building monitoring of settlement and crack development to assess damage caused by subway construction work.
“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 3D sensor measures displacements in three spatial axes with a repeatability of ±50 µm. It is the right choice for settlement measurements, convergence measurements, and crack and joint monitoring when rotation does not need to be measured. For applications involving tilt or rotation, the 6D sensor is the more suitable solution.
Movements along three spatial axes and rotations around three axes are measured simultaneously. Repeatability: ±50 µm and ±1°. Patent...
