Structural Health Monitoring

Structural monitoring (SHM) provides information on the state of the structure in real time using a variety of detection technologies. SHM systems are designed for monitoring, testing and performance of structures such as:

• Bridges and dams
• Airframes
• Buildings and stadiums
• Wind turbines
• Vessels and platforms

The recent developments in sensor technology, especially when BeanAir wireless technology is considered, have opened up new gates in terms of health monitoring and preemptive fault detection.

Structural Health Monitoring on Bridge
Bridges are subject to aging, harsh environmental conditions and excessive loads. Consequences of impaired physical condition can be as severe as the collapse of the structure, causing great financial loss or even casualties, but even major protective maintenance and upgrading works or replacement of the bridge are expensive and troublesome. BeanAir® provides a Wireless Sensor Network solution suitable for bridge monitoring enabling Engineering practices to monitor assets remotely without the need for costly site visits. 

Vibration Monitoring

  • Thanks to it’s very low noise (45 µg/√Hz for the ±2g version)
  • Vibration waveform, frequency spectrum (FFT) and Velocity are displayed in real-time on our monitoring software (BeanScape® Wilow® ).

  • The innovative measurement mode Streaming with event-trigger (S.E.T.) allows to record vibration when a trigger threshold level is reached.


Tilt Monitoring

  • The BeanDevice® Wilow® HI-INC  a ULP (Ultra-Low-Power) WIFI inclinometer for tilt/inclination measurement.
  • This device comes with two measurement range (±15° and 30°) and offers a great level of accuracy of ±0.05° (±0.02° on customer request) .

  • This device is suitable for land surveying and bridge monitoring, user can setup alarms by email (from our BeanScape® Wilow®) when a threshold level is reached.


Our Wilow® product line is compatible with WIFI Bridge/Repeater, user can connect up to 7 WIFI Repeater/Bridge  with a wireless range up to 2km between each WIFI Repeater/Bridge.
