S-CPTu Tests
Using a piezocone (electric probe) has significantly improved the data obtained in static testing both in terms of measurement precision and data sampling frequency.
Pagani piezocones indeed allow the acquisition, during the continuous driving movement, of the Qc (bit resistance) and Fs (side friction) values at each centimetre of depth compared to the 20 centimetres which can be obtained with mechanical cone (Begemann).
The system also acquires seismic waves, the value of u (hydrostatic pore pressure), Tilt (the angle of the set of rods) and the dissipation time (time measured between measurement of the overpressure obtained during the driving stage and the pressure measured when releasing the driving pressure).

TGAS-12 acquisition system
TGAS-12 is an acquisition system for CPTu + S-CPTu tests which allows you to work in the field in any weather conditions.
Provided with a capacitive touch-screen monitor with good visibility even in direct sunlight, it allows operators to perform CPTu + S-CPTu tests via simple and fast procedures, without the assistance of a PC in the field.
Provided with an intuitive monitor touch-screen, it doesn't require the aid of a portable PC and it can be easily installed on the machine on site.
The collected data can be downloaded via a simple USB key.
