    Cost-effectivePile Integrity Testing is a proven tech-nique to check concrete piles in an efficient and non-destructive way before they are incorporated in the final foundation plan. The SIT-series meets the construction industrys demand for professional Sonic Integrity Testing of concrete piles. The SIT-series has been optimised for use in the field as well as for advanced interpretation and efficient management of the measurement data in the office. The SIT models are robust, easily portable and user-friendly to operate at the construction site. One person can test numerous piles per hour.

    Non-destructive Low Strain Integrity Testing With each model of the SIT-series you can verify the pile length and detect irregularities and cracks in the pile shaft after installation. This applies to both cast-in-situ and prefab piles.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 light-weight SIT-accelerometer. The SIT pres-ents a measurement signal directly on screen, enabling a direct check of the quality of the measurement. 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 the measurements are downloaded via USB to a Windows computer. Proven technology

    Profound SIT-series (SIT/sit+/SitPro)

    Pile quality is often determined by performing a low strain integrity test directly after pile driving or within days after installation of cast-in-situ piles. This Sonic Integrity Test (SIT) of a pile is a quick non-destructive method for detecting pile defects in concrete piles. With a SIT system you can verify the pile length and check the integrity of foundation piles on defects after installation. Testing can point out which piles require further examination.

    The SIT-series meets national and international standards such as ASTM D5882-07, CUR aanbeveling 109, EA-Pfhle and AFNOR NF P94-160-2.

    Since the early 1960s Sonic Integrity Testing has been per-formed to reduce the risk upon foundation failure caused by pile damage. Profound, pioneer in the field of profession-al pile testing research and equipment, has over 50 years worldwide experience and continuously strives to make the best technology available to its clients. The SIT-series is the latest generation of sonic integrity systems. SIT has proven to be a reliable and professional tool. The reliability of the concept has been proven by the hundreds of SIT-systems in use around the world.

    Innovative Depending on the usage frequency and measurement purpose, Profound offers you the choice out of three models to meet your specific measurement needs. The SIT-series comprises three models SIT, SIT+ and the topmodel SITpro. Each model is provided with an accelerometer, cables, hammer and signal process-ing and analysis software. Depending on the chosen model, the SIT system enables you to continuously perform tests between 4 up to 8 hours with the integrated high-per-formance Lithium battery. With a SIT-system you also re-

    SIT-accelerometer (SIT.20800)The Profound accelerometer for the SIT-series has been custom-designed for high-performance sonic integrity testing of installed foundation piles.

    The pile head is struck with a special hand-held hammer that sends a shock wave down the pile shaft. The signals are measured by the sensitive SIT-acceleration sensor pressed onto the pile top. The response of the pile is shown in a reflec-togram on the display of the SIT-system, enabling a direct quality check of the measurement.

    Advanced designThe advanced design of the accelerometer in combination with the carefully se-lected components resulted in an ergonomic, lightweight and high-end sensitive acceleration sensor with high linearity and repeatability. The lightweight sensor registers exceptionally well the response to the hammer blow.

    Due to this combination users can perform measurements efficiently, as the high-quality sensor can be placed fast and very accurately on the pile head. Thus the system generates high-quality reflectograms, providing users with accurate infor-mation about the pile shaft and possible defects.

    Digital IDThe SIT-acceleration sensor has an electronic datasheet, which also includes the serial number. Therefore, the source of measurement data can always be traced.

    High-performanceThe SIT-acceleration sensor in combination with the SIT-sys-tem provides high signal stability and extremely low noise level. Thus capable to detect even smaller defect in piles.
