Foundation Pile Quality Instrument Low Strain Pile Integrity Testing Instrument
GD-P8000 wireless pile dynamic tester uses the low-strain reflection wave method to detect the integrity of concrete pile foundations. The control end of the wireless dynamic tester uses a mobile terminal under the Android platform as the data receiving end, and the collection end uses a wireless dynamic tester. The collected data is sent to the receiving end in real time through wireless communication for data display, analysis, and storage.
True 24-bit data acquisition
High-fidelity design, true 24-bit A/D data acquisition, more realistic test waveform, avoiding excessive noise and signal distortion caused by floating-point amplification.
Wavelet analysis processing technology
The new wavelet analysis processing technology effectively extracts the reflection signal at the bottom of the pile.
Wireless transmission
Wireless transmission is used between the sensor and the tablet computer, which is convenient and fast, and gets rid of the trouble of entangled signal lines.
Software online upgrade
The detection software in the tablet computer can be intelligently upgraded online, and with the "Zhibolian Engineering Detection Management System", the detection data can be uploaded in real time to achieve standardized management of detection work.
