For determining the natural frequency of the ultrasonic pulse transmitted through the material. Measurement of the Attenuation of the Transmitted Energy.

BS EN 12504-4:2004

The measurement of pulse velocity can be used for the determination of the uniformity of concrete, the presence of cracks or voids, changes in properties with time and in the determination of dynamic physical properties. This determination is suitable for the examination of the pulse path and gives indications about possible cavities, delaminations, multi-layer elements or othjer similar dishomogeneities.

Nominal frequency kHz approx.

The unit includes an excel spreadsheet for the acquisition of the waveform on the PC for further elaborations. Supplied with hard plastic carrying case.

Specification for testing machines BS EN Overview Product Details This European Standard, a part of the BS EN series, specifies a dn for the determination of the velocity of propagation of pulses of ultrasonic longitudinal waves in hardened concrete, which is used for a number of applications.

Search all products by. The pulse velocity can be combined with the rebound hammer value for the strength evaluation of concrete. Very often the transit time only is not enough to identify disomogeneities and little damages as for example microcracking of concrete which are, on the contrary, well located with this technique by properly processing the acquired waveforms. This European Standard, a part of the BS EN series, specifies a method for the determination of the velocity of propagation of pulses of ultrasonic longitudinal waves in hardened concrete, which is used for a number of applications.
