High strain dynamic load testing and pile driving monitoring system. The Pile Driving Analyzer® (PDA) system of Pile Dynamics, Inc. (PDI) is the most widely employed system for Dynamic Load Testing and Pile Driving Monitoring in the world. The PDA eighth generation (PDA-8G) acquires data from accelerometers and strain transducers attached to a pile or shaft so that High Strain Dynamic Tests (ASTM D4945) may be performed. The tests require the impact of a pile driving hammer or a suitable drop weight.
The PDA-8G is designed with the field engineer in mind. The 8G allows for up to 16 channels of data acquisition (wireless mode) with “smart” sensors knowing their calibrations and allowing any sensor to plug into any acquisition channel. Its screen, with a higher resolution LCD than previous generations of PDAs, displays measured signals and calculated results in real time, and allows more options to be viewed simultaneously.
