Product Details

Standard Components: 

1. Wireless Sensor.

2. Pad and charger.

3. Hammer Tools.

Technical Features:

1. Wireless connectivity between accelerated sensor and PDA allows easy and more flexible usage on site. PDA can work up to 10 meters away from the accelerated sensor.

2. Real time on-site processing such as smoothing, differential, filtering, exponent and linear amplification can be given to tested waveform.

3. The signal noise can be eliminated by taking average superposition of multiple signals. Superposition signals can be checked at any time, and poor-quality signals can be rejected.

4. Project/pile testing data can be easily saved, accessed, edited, or deleted.

5. Gain value can be adjusted according to length of pile and top surface condition of pile.

6. Intelligent sensor can complete the acquisition work, and upload the data to the computer through the Wi-Fi, get rid of signal wire entanglement, efficient, fast and smooth.

7. True 24 bit A/D data acquisition makes test waveform more real, avoiding the noise and signal distortion caused by floating point amplification.

8. New wavelet processing method can effectively judge the integrity of foundation pile in complex situation.
