Crack Monitoring
Settlement, shrinkage, and stress cracks in concrete and masonry that primarily open along two axes. A complete history of movement for expert reports and damage assessments.
Relative motion in the X and Y directions with a repeatability of ±100 µm. Built-in temperature sensor. 10-year battery life. Made in Austria.
Settlement, shrinkage, and stress cracks in concrete and masonry that primarily open along two axes. A complete history of movement for expert reports and damage assessments.
At expansion joints and connection joints where movement in the plane is to be captured without the Z-component being relevant.
The 2D sensor monitors cracks in adjacent buildings before, during, and after pile driving, excavation, and blasting work.
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.
Up to 10 years of battery life with daily use. Easy, user-replaceable batteries using standard alkaline AA and D cells.
Transmission via LTE-M directly to the data hub. No wiring required on the structure.
A built-in temperature sensor records the ambient conditions to ensure accurate motion interpretation.

“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 2D sensor is the standard solution for crack monitoring and joint monitoring when movement occurs primarily along two axes. For cracks with a three-dimensional component or applications involving rotation, the 3D sensor or the 6D sensor is the more appropriate choice.
