“Enhance interpretation quality and speed. You can choose a reference pile or create a site average for measurements, which can be overlaid on all individual signals. This makes signal comparison effortless.”

Characteristics

Available in three models: SIT, SIT+ and SITpro. Your choice depends on the usage frequency and measurement purpose.
SIT-systems fully complies with ASTM Standard D5882-16, EA Pfähle 2012, CUR-Aanbeveling 109:2013, AFNOR NF P 94-160-2 and NF P 94-160-4.
Optimal user-friendliness in the field: Each SIT consists of an acceleration sensor, hammer, cables and robust data acquisition and signal processing unit including full colour screen. The SIT accessories items are easily carried thanks to the robust, weather-resistant case.
The SIT-system shows the measurement signal directly on the full colour screen, in order to verify on the spot that tests have been performed correctly. It is up to the user how many signals are stored per pile.
A signal can be stored and viewed on the system itself later on (for verification the pile has been checked).
After data transfer via USB, the full data analysis and report is done with the SIT PC software.
Accurate testing: The unit has been equipped with a 24 bit A/D converter for optimum measurement signal processing, which benefits the accuracy and facilitates any further interpretation.
Reliable: Results can be optimally reproduced.
Expert dedicated Windows software allows for the data to be put into professional pile charts. Reporting and analysis software are tailored to your requirements including pile average on screen and in print, image copy or *.pdf report.

Operation

The measurement is performed by hitting the pile head with a hand-held hammer and measuring the response on the head with the sensitive and lightweight SIT-accelerometer. The SIT presents a measurement signal directly on screen, enabling a direct check of the quality of the measurement.

Application

Sonic Integrity Testing (SIT) is a widely used measurement method to check the integrity of concrete foundation piles. This Low Strain Impact Test is a quick, non-destructive method to reduce the risk upon failure of concrete cast-in-situ or prefab piles. With a Profound SIT system you check the pile shaft for defects or irregularities. Measurements can indicate whether the foundation pile will be capable of passing on the load to the bearing layers.

SIT-mounted accelerometer

The Profound mounted accelerometer for the SIT-series has been designed for high-performance integrity testing for large diameter bored piles. This sensor enables optimal circumstances to perform measurements with Wave Hammers or instrumented hammers.

The SIT-mounted sensor is an alternative to the hand-held sensor whereby the sensor is fixed on the pile head using a separate mounting plate. One or more mounting plates must be mounted on the pile head prior to the actual measurement. During the measurement the rigid connection between the sensor and pile head ensures optimal high-quality measurement results. The sensor registers the response to the hammer blow exceptionally. Thus providing users with accurate information about the pile shaft, stiffness and possible defects.

Data handling

If approved, measurement signals are stored in the unit with additional information such as pile number, area, date and time stamp, gain and filter settings and notes. For each pile multiple signals should be acquired for proper evaluation. For further analysis, interpretation and validation of the measurements are downloaded via USB to a Windows computer.

Academy

The main goal of Profound Academy SIT course is to teach and further train in the use of the Profound SIT-series in processing and analysing measurement signals including an introduction to the basic principles of low strain integrity testing.

Attendees will be able to perform Sonic Integrity Testing of piles in a professional way, making the most of the technique and the system.

During the SIT course, the course instructor will cover the theory behind Sonic Integrity Testing, how to optimally work with the SIT system in full compliance with the main codes, intepretation guidelines, and reporting on measurement signals will be discussed.
