Ambient Vibration Testing
The Larzé ambient sensors have the exactitude and internal power to conduct state of the art ambient vibration analyses. By using the sensors in a mesh and deploying them on your structure's critical points, you can extract the information necessary for an extensive look at your structure. These wireless sensors are controlled via a user-friendly Android application, allowing for very simple and rapid testing.
These analyses allow for the detection of hidden defects, undocumented structural modifications and integrity concerns not detected by visual inspection and traditional engineering practices which can significantly improve disaster preparedness and recovery plans.
The wireless Larzé sensors can be deployed across your structure by staying synchronized for multiple hours
Our sensors bring ease of use to complex ambient vibration tests with IP66 waterproofing, optional GPS and cellular connectivity for precise synchronization as well as up to 32 sensor meshes in order to extract minuscule vibrations from your structure. The data can be easily extracted via micro-USB or pushed directly to our cloud servers.
Ambient vibration tests can garner even greater results when done periodically. A baseline is made through a first test, which is similar to the DNA or fingerprint of the structure. Additional tests can show any differences in the structure done by damages or the aging of structures.
These periodic tests can be done after any significant events or every few months or years for more important and at-risk structures.
Our Larzé Vibration System has been developed in-house in order to perform our state of the art ambient vibration test. Once deployed, the sensing test is initiated and monitored by a custom phone application. The data is sent to the cloud for analysis by our team of experts and the results are sent back to you.
Structural Health Monitoring
Set up monitoring thresholds
Receive notifications on your devices
Once in the cloud, a web portal is used to control the permanent sensor installation. You can configure the sensor network, threshold methods and levels for creating alarms for strong motion events. There you can also schedule period ambient vibration measurements.
Another site can allow users to see the data records both from temporary and permanent systems. You can also create building geometry and assign sensor nodes based on your data.
We are currently working on a dashboard for the results, events and alarms as well as adding more data analytics.

With the Larzé cloud system, vibrations of nearby construction projects or specialized machinery and equipment can be monitored in real time. Thresholds can be set to send real-time notifications once limit vibrational levels have been exceeded.
Close monitoring of excessive vibrations is often an important step in large construction or excavation projects in order to protect surrounding structures and their foundations.
