Click to learn more. Take the smart route to manage medical device compliance. This determination is suitable for the examination of the pulse path and gives indications rn possible cavities, delaminations, multi-layer elements or othjer similar dishomogeneities.
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.
BS EN 12504-4:2004
Two pieces are required. Measurement of the Attenuation of the Transmitted Energy.
It can also be used for estimating times for formwork striking. Also suitable for determining the Dynamic Modulus of Elasticity. Very often the transit time 125044 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.
