Structural health monitoring


Structural health monitoring

Data acquisition systems are used in structural health and seismic bridge monitoring projects ranging from structural mechanics to continuous monitoring of large, complex bridge structures.

The monitoring systems provide distributed, high-channel-count and remote monitoring for highway overpasses, roads, buildings, and bridges. We provide a total solution from DAQ systems and data loggers to sensors and monitoring software.

Total Turn-key Solution: The bridge monitoring solution offers complete and highly accurate data acquisition systems, data loggers (including wireless dataloggers), and the possibility to connect all necessary sensors that are used info structural health monitoring projects.

Totally Distributed System: The DAQ devices are designed to be distributed under any condition. EtherCAT technology allows devices to be placed near the sensors and connected with a single cable for power, data, and synchronization. The cable can span up to 100m between DAQ nodes or virtually unlimited using EtherCAT to fiber optic converters.

Any Sensor: Input amplifiers offer support for any strain gauge sensor, low-frequency accelerometer sensors for seismic activity monitoring, temperature, and weather factors.

Perfectly Synchronized: All data channels are synchronized well below microsecond accuracy, required for deep structural analysis.

Amazing Dynamic Range: With dynamic ranges up to 160dB, our customers are claiming they can see fish hitting the structure.

Wide Variety of Configuration: From extremely rugged IP67 units with very high dynamic range to cost-effective solutions offer a tailored approach for virtually any structure with the possibility to monitor and analyze thousands of data points.

Powerful Software: The software offers real-time diagnosis, pre-processing, and data reduction with powerful math. A wide variety of storage options are possible with powerful visualization choices.

Open Interfaces: Data is available in a wide variety of formats, from exported data to live OPC UA interface or modern cloud data services.

Operational Modal Analysis (OMA): Use recorded time data to estimate modal models. With OMA the dynamics of the structural vibrations can be determined directly from the sensor input data via the  software.

Remote Operation: The entire system can be remotely operated offering triggered storing, alarms, and other monitoring features with capabilities to store data locally or at distant remote locations.
