SCXT3000 is a self-contained sonic logging system, suitable for testing concrete piles, barrettes and other mass concrete structures.
Engineered by JF Strainstall's own development team, this ultra-sonic pile testing system is supplied with a military spec rugged notebook computer as standard, enabling the operator to perform testing in difficult conditions.
The electronic, stainless steel winch unit is easy to operate by a single user. Transducer cables can be supplied to customised lengths and are lifted with submarine type connectors which are also compatible with CS87 or CS97 transducers.
Benefits of the SCXT3000 system:
- Calculation of FAT and energy changes
- Compliant to ASTM 6760 and AFNOR NFP94-160-1
- User friendly reporting software
- Military spec rugged notebook
- Accommodates up to 12 tubes and 66 profiles
- 320GB of storage
- Full equipment training available
- Complete test package available
All of our equipment is supplied fully calibrated to UK national standards.

The SCAP3000 comprehensive analysis software enables defects to be fully assessed on site, with up to 12 tubes (66 profiles). Signal threshold levels can be selected both manually and automatically.
The software enables the user to produce complete reports, including a pile data sheet to show tube references, levels, depths tested, plumbed lengths and interpretation. Signal threshold levels can be selected both manually and automatically.
The waterfall plot, signal energy plat and FAT (First Arrival Time) plots can be displayed individually or together, enabling the user to differentiate between features such as tube de-bonding and true concrete defects.
2D and 3D tomography modules provide easy to read visuals and each individual signal is also stored for post analysis if required.
SCXT3000 uses ultra-sonic transducers to measure the transit time of sound in concrete through steel tubes which have been installed in foundations during construction.
As the winch turns, the emitter sends ultra-sonic signals which travel between selected tubes to a receiver and captured as a time / amplitude trace every 1cm of the pile length.
Single traces are combined into one sonic profile or waterfall plot. The operator can choose to display the first arrival time (FAT) and signal energy simultaneously. The first arrival time can be used to determine the ultrasonic pulse velocity if the distance between the tubes is measured.
