Wireless Pile Integrity Test (P.I.T.)

By using the reflected wave method, the instrument is used to assess the integrity of concrete pile and identify the extent and location of the pile defect. It can be used for testing drilled piles and hammer piles. It can also be used for testing the exposed top surface of constructions such as pillars.

  • Intelligent sensor can complete the acquisition work by himself, and upload the data to the computer through the WIFI, get rid of signal wire entanglement, efficient, fast and smooth;
  • True 24 bit A/D data acquisition, the test wave form is more real, to avoid the noise and signal distortion caused by large floating point amplification;
  • The real-time analysis of detected waves, a new wave let analysis in complex situations can be more accurate to judge pile integrity;
