Ultrasonic ”cross-hole” test system, two channels, for piles and foundations

Ultrasonic cross-hole” test system TWO channels for piles and foundations
Complete system for non-destructive structural inspections through ultra-sounds on piles deep foundations infrastructural works or buildings.
The equipment consists of a computerized central unit to which it is possible to connect according to the type of survey probes for standard
direct contact tests or motorised reels controlled electronically on which probes are assembled with drilling power for Cross-Hole
surveys. The microprocessor system is able to ensure the constant alignment between probes lowered down the tubes when taking the measurement. The data acquired at each single pulse are displayed in real time on the large colour monitor allowing an immediate visualization of possible imperfections in the inspected structure. The cross-hole survey is managed in automatic mode; the operator is only required to position the encoders for reading the position of the motorised probes on the tubes and the initial alignment on the pile head. Once the test is concluded it is possible to print the test report with data in the construction site.
