Dual-axis tilt sensor

      The application of tilt sensors in the field of bridge engineering is an important component of modern bridge health monitoring and safety management. Leveraging their high precision, real-time capability, and excellent durability, tilt sensors provide valuable data support for the daily operation and maintenance, safety warnings, and damage assessment of bridges. The following is a detailed description of the specific applications of tilt sensors in bridges:

1. Monitoring Bridge Deformation and Stress Distribution:  In bridge structures, tilt sensors are embedded in key load-bearing components such as bridge towers, piers, and main girders. By continuously measuring and recording the angular changes in these parts, they reflect the subtle deformations of the bridge under static loads (e.g., self-weight, prestress) and dynamic loads (e.g., vehicle traffic, wind loads, thermal expansion and contraction due to temperature changes). This data helps engineers understand the actual stress state and structural health of the bridge, particularly the cumulative deformation after long-term service, which is crucial for assessing the remaining service life and predicting potential damage.

2. Enhancing Seismic Performance Evaluation and Post-Disaster Inspection:  In earthquake-prone areas, the seismic performance of bridges is a key consideration in design and operation. Dexeer tilt sensors can monitor the dynamic response of bridges during earthquakes or other strong vibration events in real time, including parameters such as relative tilt, swing amplitude, and recovery speed of various bridge parts. This information helps engineers accurately evaluate the bridge's performance under load and quickly assess whether the bridge meets safety standards after an earthquake, providing a scientific basis for subsequent repairs or reinforcements.

3. Bridge Safety Warning and Emergency Response:  Embedded in bridge monitoring systems, tilt sensors enable real-time online monitoring of key bridge parts. Once the tilt angle change exceeds a pre-set safety threshold, the system automatically triggers an alarm, notifying management personnel in real time for on-site inspection or necessary measures such as traffic restrictions or closures. This effectively prevents serious accidents such as bridge collapses caused by excessive deformation.

4. Precise Structural Deflection Calculation and Mechanical Model Validation:  By deploying Dexeer tilt sensors on components such as main girders and suspension cables, the deflection changes of the bridge under various loads can be measured. Combined with modern computer-aided engineering software (e.g., ANSYS, Midas) for finite element analysis, the actual stress distribution and fatigue damage conditions of the bridge can be calculated. This further verifies and refines the bridge's mechanical model, providing quantitative basis for rational design, renovation, or reinforcement.

5. Intelligent Remote Monitoring and Big Data Analysis:  With the development of IoT, cloud computing, and big data technologies, modern bridge monitoring systems increasingly use tilt sensors with wireless transmission capabilities. These sensors can send collected data to cloud servers in real time via wireless networks, enabling remote monitoring and data analysis. Operation and maintenance personnel can view the real-time status of the bridge without being on-site. By combining artificial intelligence algorithms to mine and analyze large amounts of historical data, the patterns of bridge structural performance evolution over time are revealed, providing decision support for long-term health management and preventive maintenance of bridges.

      In summary, the widespread application of tilt sensors in bridge engineering has significantly improved the accuracy, efficiency, and intelligence of bridge structural monitoring, making major contributions to ensuring structural safety, extending service life, and enhancing operation and maintenance efficiency. In the future, with further advancements in sensor technology, we look forward to seeing more innovative sensor products and monitoring solutions applied in bridge engineering, better serving infrastructure construction and safety operations in China and beyond.
