each measurement to accommodate irregular shaped objects (see “3.5
Measurement Modes” – Line Scan).
Measurement Settings
Measurement Range
Short range (default). For measurements up to approximately 800 μs.
This corresponds to a path length of approximately 3 m for normal concrete. This provides the maximum measurement resolution of 0.1 μs.
For larger objects select the long range. In this case the measurement resolution is 1 μs.
The measurement screen indicates (--- μs) if a measurement is out of range.

Pulse Repetition Frequency
Pulse Repetition Frequencies (PRF) of 5 Hz to 40 Hz (measurements per second) may be selected. High values should be selected only when the instrument is used on large objects with high receiver amplification settings. In such cases, it helps to increase the update rate on the display.
For general concrete or ceramic materials testing a PRF of between 10-
30 Hz is normally used.
The transducers supplied with the instrument are not damped and, therefore, on being excited by the transmitter they have a long ring-down time.
The ring-down time may exceed the pulse interval when the PRF is set

Enter the number of measurements to be made.
Position the transducers as shown in ‘Step 2’ on the screen.

Measure the transmission time at distance ‘b’.
Result shows the transmission times t1 and t2 and the crack depth ‘d’.
An incorrect measurement of t1 or t2 may be deleted and repeated before continuing.
An error message is displayed for an invalid measurement
(t2 < t1 or t2 > 2 x t1).
Record the first measurement at distance ‘b’.
Move the receiver a further distance ‘b’ and measure again. Continue until you have completed the series.
NOTE! For this method to give good results, the crack must be perpendicular to the surface. It must also be free of water or debris which would allow the wave to propagate through the crack. The crack must be sufficiently wide to prevent the wave from simply propagating around it. There must also be no rebars within the vicinity of the crack. If any of these conditions occur, the result will be severely affected and it may appear that the crack depth is much shallower than is actually the case.
The pulse velocity is calculated from the slope of the curve.
NOTE! If the points recorded show a discontinuity, it is likely that a surface crack or surface layer of inferior quality is present. In this case the measured velocity is unreliable.

3.6 Measuring with Pundit PL-200
Three transducer arrangements are commonly used.
Direct Transmission: The optimum configuration with maximum signal amplitude. The most accurate method of pulse velocity determination.
Path length is measured from centre to centre of the transducers.
Move the transducers the distance ‘a’ to the next point on the grid.
If the distance ‘x’ does not change press the snapshot icon again to make the second measurement and so on.
© 2013 Proceq SA 13
Table of Contents
Indirect Transmission: Signal amplitude is approximately 3 % of signal amplitude when compared to direct transmission. Path length may be uncertain. Use the surface velocity mode mode to eliminate this uncertainity. The pulse velocity will be influenced by the concrete surface zone. Where possible, carry out a comparison with a direct transmission measurement to eliminite any uncertainly.
For rougher surfaces, a thick grease or petroleum jelly is recommended.
In some cases it may be necessary to prepare the surface by smoothing it. If this is not possible the exponential transducers (Part No. 325 40 170) should be considered.
For line scans a test grid should be drawn out on the surface.
Amplitude Analysis
Amplitude analysis is a method developed at Tonji University in Shanghai and is widely used throughout China for comparison testing of concrete in structures.
In order to record the amplitude the Amplitude Analysis Marker must be set in the settings menu . When this is set, the amplitude is recorded along with the transmission time as part of the test result.
Semi-direct Transmission: Sensitivity is somewhere between the other two methods. Path length is measured from centre to centre of the transducers.
Preparation
Basic preparations are common to each application. The distance (path length) between the transducers should be measured as accurately as possible (unless you are measuring in transmission time mode).
It is essential in all ultrasonic pulse tests to use some form of couplant between the faces of the transducers and the material under test. Failure to do so will result in a loss of signal due to inadequate acoustic coupling.
The ultrasound couplant provided provides good coupling when used on concrete or other materials having smooth surfaces. Silicone grease, medium bearing grease or liquid soap may also be used to good effect.
A reference measurement is made on a section of concrete of known quality. t

Subsequent measurements on the structure are compared with these two values and an inference is made about the concrete quality based on this.
Six different cases are identified which allow the user to make a statement about the concrete quality.

5. transducer Selection Guideline
Physical influences on transducer Selection
The selection of the correct transducer for the application is largely dependent on the aggregate (grain) size and the dimensions of the test object.
Effect of particle size
Inhomogeneities (e. g. aggregate particles, voids) in concrete influence the propagation of an ultrasound pulse. They will scatter the signal. The effect is very large if the size of the aggregate is equal to or larger than the wavelength of the ultrasonic signal. This influence can be significantly reduced by choosing the pulse frequency, such that the wavelength is at least twice as large as the aggregate size.
It also follows that it is very difficult to detect an anomaly if it is smaller than half the wavelength.
For rocks and other fine grained materials such as ceramics and wood, the grain size is less significant. For such materials, the size of the object to be tested is the most significant factor.
Best results have been obtained on wood with 54 kHz.
For ceramics, the small sample size and fine grain means that 250 kHz or
500 kHz is most widely used.
Effect of sample size
The pulse velocity is reduced significantly if the lateral dimensions (perpendicular to the direction of transmission) is less than the wavelength.
Higher frequency signals, have a better defined edge and therefore make it easier to identify the onset of the received pulse. However they are more influenced by scattering. A 500 kHz signal has a wavelength of around 7 mm (assuming the speed of sound to be 3500 m/s) and is heavily scattered by the coarse aggregate in concrete, limiting the transmission to a few decimeters at most. A 24 kHz signal has a wavelength of around 150 mm and is largely unaffected by scattering. The maximum transmission range may be several meters.
transducer Wavelength
The wavelength may be easily calculated:
Wavelength = ultrasonic pulse velocity / frequency
For concrete, the ultrasonic pulse velocity ranges from 3000 m/s (poor quality) to 5000 m/s (high quality). An average value for ordinary concrete of 3700 m/s (longitudinal wave) and 2500 m/s (shear wave) have been used for the computation of the wavelengths, the maximum aggregate size and the minimum lateral dimension of the test object.
NOTE! For ultrasonic measurements made on rock,
ASTM D2845 recommends a minimum lateral dimension of 5x the wavelength. It also recommends using a wavelength at least 3x the average grain size. e. g. An NX core specimen has a diameter of 54.7 mm
A transducer frequency of 250 kHz or 500 kHz would be recommended for this size of specimen based on this recommendation, (depending on pulse velocity of the rock types to be tested). Maximum grain size would be 5 mm or 2.33 mm respectively.

Table of Contents
P-waves vs. S-waves
In a P-wave (longitudinal wave) the particle displacement is parallel to the direction of wave propagation. The particles oscillate back and forth about their individual equilibrium positions.
In an S-wave (shear wave) the particle displacement is perpendicular to the direction of wave propagation. The particles oscillate up and down about their individual equilibrium positions as the wave passes by.
Measuring with S-wave Transducers
Detection of the shear wave (S-wave) requires the use of the waveform display in order to manually locate the onset of the shear wave echo as it is always preceded by a weak P-wave component that is detected by the automatic triggering.
S-waves travel in a one-dimensional plane. The strongest signal appears when the transducers are correctly aligned. This property can be used to correctly detect the S-wave component of the received signal.
Misaligned by 90°
Weak S-wave component
Correctly aligned
Strong S-wave component
Much stronger
S-wave component when the transducers are correctly aligned.
On small samples the S-wave transducer may also be used to determine the P-wave transmission time. The dual cursor mode allows trigger points to be monitored on the screen.
A calculator is provided in the PL-Link software to determine Poisson’s
Ration and E-Modulus from the P-wave and S-wave pulse velocities. For the E-modulus calculation, it is also necessary to enter the density of the material under test.
Weak S-wave component with the transducers misaligned.

Clicking “Auto Scale” adjusts the zoom parameters of the waveform display to an optimum setting.
8.6 Conversion Curves
Pundit Touchscreen Unit allows compressive strength estimates to be made using pulse velocity measurements or a combination of pulse velocity and rebound hammer measurements.
To do this it is necessary to create a conversion curve and upload this onto the instrument.
Conversion curves are very much specific to the concrete under test and there are many examples in the literature.
Pundit Touchscreen Unit allows either polynomial curves or exponential curves to be programmed and in the case of a combined ultrasonic/rebound value measurement a curve based on the SONREB (SONic RE-
Bound) method may be entered.

The new curve will now appear in the drop down list and may be loaded onto the Pundit Touchscreen Unit.
