Cross-Hole Analyzer for foundation piles Wireless modular version ASTM D6760 Controls Group

The cross-hole method is a way to analyze the foundation piles of buildings, which, with the use of cross-hole ultrasonic pulses, allows accurate, high-resolution tests to be carried out. An ultrasonic wave is sent from a transmitter to a receiver and is conveyed automatically by the device along the entire length of the pile via the pipes embedded into it during casting. The speed of the sonic wave and its energy are strongly influenced by the quality of the concrete and it is therefore possible to assess the characteristics and give a tomographic representation in 2D and 3D called diagraphy.

Feature:

Integrated wireless system with 2 motorized reels; expansion options for 1 - 2 channels;
with multi-reels system (up to 4) the tomographic investigation is performed providing complete information on pile quality and homogeneity over its whole length;
the system is completely managed via a rugged Android tablet (included);
easily transportable with the very small wheeled suitcase;
user-friendly and intuitive software.
