Pile Dynamics has expanded its range of Pile Driving Analyzer (PDA) sensors by adding wireless technology to its capabilities.

Dynamic Foundation Testing requires the acquisition of sensor data from a PDA and the analysis of the data by a qualified engineer. Wireless technology allows for real-time transmission of data from the site to an office and crucially eliminates the need for weighty cabling.

“This is one for the future; the technology is both helpful and amazing,” said Aksan Kawanda, an engineer with Geotech Engineering in Jakarta, Indonesia.

Kawanda was speaking after the successful implementation of the wireless sensors on a near-shore jetty in West Java. Several of the piles were dynamically tested with a PDA model PAX using wireless sensors.

The accelerometers and strain transducers on the near shore pile transmitted data to the PDA, which remained safe and dry on shore a considerable distance away.
