High-Precision CANopen Inclinometer for High-Rise Building Structural Health Monitoring

Reliable Angular Measurement for Building Tilt, Structural Deformation and Infrastructure Monitoring

As high-rise buildings become increasingly complex, monitoring structural conditions over time is essential for building safety and infrastructure management. Changes in building inclination, uneven foundation settlement, and structural deformation are important factors that engineers need to monitor and evaluate throughout a building's service life.

For structural monitoring system integrators and engineering contractors, selecting an accurate, stable, and reliable inclination sensor is an important part of developing an effective monitoring solution.

The ACA816T/ACA826T High-Precision CANopen Inclinometer, developed by RION Technology, is designed for high-precision angle measurement. Featuring 0.0005° resolution, single-axis or dual-axis measurement, full-temperature compensation, and CANopen digital output, it provides accurate inclination data for integration into high-rise building and infrastructure monitoring systems.

Why Is High-Precision Tilt Monitoring Important for High-Rise Buildings?

During long-term operation, high-rise buildings may experience changes in structural inclination due to foundation settlement, uneven loading, environmental conditions, and other external factors.

For engineering professionals, monitoring these changes helps provide measurement data for structural condition assessment.

1. Building Tilt Monitoring

Small changes in building inclination may indicate changes in structural conditions. Installing inclinometer sensors at selected monitoring points allows engineers to track angular variations and evaluate structural tilt trends.

2. Foundation Settlement Assessment

Uneven foundation settlement can cause changes in the inclination of buildings or structural components. High-precision inclination measurement provides supporting data for engineers when assessing settlement-related structural changes.

3. Structural Deformation Monitoring

Structural monitoring projects often require measurement at multiple locations. Single-axis or dual-axis inclinometers can provide angle data at different monitoring points, helping engineers analyze structural inclination changes.

4. Structural Vibration Environments

External disturbances and structural vibrations can affect monitoring equipment. The ACA816T/ACA826T features electromagnetic compatibility design, shock resistance, and vibration resistance for demanding industrial measurement environments.

Key Features of the ACA816T/ACA826T Inclinometer

The ACA816T/ACA826T adopts a capacitive micro-pendulum measurement principle. When the sensor tilts, the gravitational component acting on the sensing element changes its capacitance. The signal is amplified, filtered, and converted into an inclination measurement.

Its main features include:

1. High Resolution: 0.0005° resolution for detecting small angular changes.

2. Single/Dual-Axis Measurement: Available in X-axis or XY-axis configurations.

3. Multiple Measurement Ranges: ±3°, ±10°, ±15°, and ±30°.

4. CANopen Output: Digital communication for integration with compatible monitoring systems.

5. Full-Temperature Compensation: Operating temperature from -40°C to +85°C.

6. IP67 Protection: Suitable for installations requiring dust and water protection.

7. High Environmental Resistance: 100g@11ms shock resistance and 10grms vibration resistance over 10–1000Hz.

Technical Specifications

Easy Installation and System Integration

The ACA816T/ACA826T features a compact aluminum housing and screw-mounted installation design. It can be fixed to the measured object's surface using four M4 screws, with two optional 3mm positioning holes.
