Products Specifications
The Pile driving analyzer (PDA)uses reflected wave method to detect the integrity of the foundation pile, and determine the degree and location of the defects of the pile body. It can be used to test cast-in-situ piles and driven piles, and can also be used to test structures with exposed top surfaces (such as bridge pier, etc.).
Features
Real 24-bit A / D data acquisition, more realistic test waveform, clear pile bottom signal
Wireless transmission between the sensor and the tablet
Cost-effective, fast response, smooth and natural detection process.
