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 ±0.1°. Patented in the EU and the U.S.

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.

“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."

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.
The 3D sensor measures absolute positional changes along three spatial axes (X, Y, Z). The 6D sensor additionally measures rotations around all three axes. This allows it to capture the complete motion profile at a measurement point with a single installation. For applications where only translations are relevant, the 3D sensor is the simpler solution.
The battery is designed to last for ten years with hourly measurements. No battery replacement is necessary during this period. This is particularly important at hard-to-reach measurement points, such as bridge bearings or tunnel linings, where maintenance would be time-consuming.
The 6D sensor transmits its measurement data wirelessly to the data hub via LTE-M and Wi-Fi. The protocol best suited for your project depends on the on-site infrastructure. If cellular reception is limited, the sensor uses Wi-Fi or a gateway. Our team can help you choose the right option.
The reference object and sensor can be attached to the component using two screws, adhesive, or magnets. Activation is triggered by placing a magnet on the sensor or connecting the battery cable. No special tools or on-site technical personnel are required. Our system is ready for use in just a few minutes.
