SIT Wavehammers

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.

SIT Software 9.0

“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 test is performed by striking the pile head with a hand-held hammer. The response is measured using the sensitive and lightweight SIT accelerometer. The measurement signal is displayed instantly on-screen, allowing for immediate quality verification.

Application

Sonic Integrity Testing (SIT) is a widely used method to verify the integrity of concrete foundation piles. This Low Strain Impact Test is quick, non-destructive, and helps minimize the risk of pile failure. With a Profound SIT system, you can easily detect irregularities or defects in cast-in-place or precast piles. The test indicates whether a pile can reliably transfer load to the bearing layers.

SIT-mounted accelerometer

The mounted SIT accelerometer is designed for high-performance integrity testing of large diameter bored piles. It is ideally suited for use with Wave Hammers or instrumented hammers.

The sensor is firmly attached to the pile head using a separate mounting plate. This fixed connection ensures reliable, high-quality measurement of the pile’s response to the hammer impact. As a result, users receive accurate information about the pile shaft, stiffness, and potential defects.

Data Handling and Analysis

Approved measurements are stored together with relevant data such as pile number, location, date, time stamp, gain, filter settings, and notes. Multiple signals should be acquired per pile for accurate analysis. The data can be transferred via USB to a Windows computer for further interpretation and validation.

Profound Academy

The Profound Academy offers a practical SIT training course focused on the correct use of the SIT system and interpretation of measurement data. Participants gain insight into the principles of Sonic Integrity Testing, learn to work in compliance with relevant standards, and improve their skills in analyzing and reporting test results.
