Bridges
At bridge bearings, the 6D sensor measures bearing movements in all six degrees of freedom. This indicates whether a bearing is operating within normal limits or whether a critical condition is developing.
Movements along three spatial axes and rotations around three axes are measured simultaneously. Repeatability: ±50 µm and ±1°. Patented in the EU and the U.S.

The 6D sensor monitors positional changes and rotations in the tunnel cross-section at the tunnel rings and support frames.

Two screws per component; activated by a magnet or battery cable. No special tools, no on-site technical staff, and no additional measurement setups.
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.
If a threshold is exceeded, our system automatically sends an email or text message notification to the designated recipients.
Data is transmitted directly to the SuessCo Datahub via LTE-M and Wi-Fi. No cable ducts, no external cabling on the building.
Up to 10 years of battery life. No battery replacement is necessary within the typical maintenance intervals for your building.

Bridge Bearing Monitoring on a Historic Steel Bridge
“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 6D sensor is the right choice whenever translations and rotations occur simultaneously and must be evaluated together. This is particularly the case for bridge bearings, machine foundations, structural joints, and historic buildings. Whereas a 3D sensor measures only translation, the 6D sensor provides a complete picture of the motion of a structure.
