High-Precision Tilt Sensor Enables Real-Time Building Safety Monitoring for Unsafe Structures

        As the number of aging buildings continues to grow, unsafe building monitoring has become an essential part of modern structural safety management. By deploying high-precision MEMS tilt sensors, engineers can continuously monitor building inclination, structural deformation, and foundation settlement, providing reliable data for safety assessment and early warning.

        In a recent unsafe building monitoring project, the RION HCA716S/HCA726S CANopen Tilt Sensor was installed at critical load-bearing points to continuously measure changes in building inclination. Featuring a high-precision 24-bit A/D converter and advanced MEMS sensing technology, the sensor delivers a resolution of up to 0.001°, enabling accurate detection of even the smallest angular changes and helping maintenance teams assess structural conditions in real time.

        The sensor supports measurement ranges from ±1° to ±180° and integrates a CANopen communication interface, allowing seamless connectivity with PLCs, RTUs, and remote monitoring platforms for real-time data acquisition, trend analysis, and automatic alarm notifications. With an IP67 protection rating, an operating temperature range of -40°C to +85°C, and excellent vibration resistance, it is well suited for long-term outdoor deployment in harsh environments.

         Compared with traditional manual inspections, continuous online tilt monitoring provides uninterrupted records of structural movement and enables early detection of abnormalities caused by foundation settlement, nearby construction activities, or environmental changes. This approach improves monitoring efficiency, reduces maintenance costs, and provides reliable data support for building safety management, disaster prevention, and structural health monitoring (SHM) applications in smart cities.
