Campbell Scientific data acquisition (DAQ) systems’ versatile capabilities make them ideal for structural health monitoring in a wide range of applications, including simple beam-fatigue, structural mechanics research, and continuous monitoring of large, complex structures. Campbell Scientific’s family of data loggers and DAQ systems are currently being used for remote, unattended, portable monitoring for highway overpasses, roads, buildings, retaining walls, bridges, and amusement park rides. Since 1974, Campbell Scientific has been known worldwide for rugged, accurate, and reliable measurement systems.

The versatility of our modular DAQ systems allows them to be customized for each application.
The modular architecture of our GRANITE™ system allows each measurement module to independently connect to a PC or DAQ. As an independent module, the real-time measurements can be displayed directly on the PC. One or more measurement modules can be connected to the GRANITE™ DAQ to create the perfect networked configuration for each application. When connected, they form a time-synchronized, distributed DAQ system.
Multiple GRANITE™ measurement modules can be distributed throughout the structure. Each module is connected to a central GRANITE™ DAQ. This networking capability decreases the quantity and lengths of the sensor cables between the sensors and the GRANITE™ DAQ. Fewer sensor cables reduces cost, improves system simplification, and lessens the risk of signal corruption from noise.
Synchronization is key to the success of a distributed network. There are three significant levels to the GRANITE™ DAQ synchronization:
Because Campbell Scientific data loggers and GRANITE™ DAQs are compatible with nearly every commercially available sensor, you can use the sensor that best meets your application. Typical sensors used for structural and seismic monitoring by our systems include:
Communication interfaces for retrieving, storing, and displaying data include direct connection to a PC or laptop, microSD cards, Ethernet, and several options for wireless communication (including built-in Wi-Fi).
Our PC-based software options support connecting the GRANITE™ measurement modules directly to a PC or scheduling remote, automated data collection from the GRANITE™ DAQ. Real-time monitoring and control simplify the entire data-acquisition process, while robust error-checking ensures data integrity. We can even help you post your data to the Internet.
Campbell Scientific’s GRANITE™ monitoring systems are used for a variety of structural and seismic applications. Monitoring possibilities on an overpass could include:
