FAQ

Is it possible to measure ultrasonic pulse velocity using the Pundit PD8000?
Ultrasonic pulse velocity measurements are traditionally made with P-waves (compression waves). The Pundit PD8000 provides the alternative of measuring pulse velocity variations using shear waves. A unique feature of the Pundit PD8000 allows the user to tag the back wall echo. The tag contains the transmission time information which can be exported for calculation of the pulse velocity.

Is it possible to detect water filled voids with ultrasonic pulse echo?
Yes, it is possible to detect water-filled voids. One of the reasons that shear waves are used in the Pundit PD8000 instruments is that in comparison with P-waves (compression waves), they are better suited to detecting water-filled cracks and voids.

How deep can I measure with the Pundit PD8000?
There is no definitive answer to this question as it depends very much on the concrete quality and the amount of steel present. Using the Pundit PD8000 instrument with the Far Field macro selected (low frequency and high transmission voltage), depths of up to 2m have been achieved. However, it is also possible that depth penetration may be limited to about 1m if the concrete quality is not good, or if there is a lot of steel present in the structure.
