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. It can also be used for estimating times for formwork striking. It is possible to use our digital test hammer to obtain the avarage value of rebound number.
Measurement of the Attenuation of the Transmitted Energy.
Ultrasonic pulse analyzer
Take the smart route to manage medical device compliance. This value can be insert in the dedicated menu of UPV tester combining a typical surface measurement with the deeper UPV transit time in order to obtain a more reliable and extended information. You may experience issues e this site in Internet Explorer 9, 10 or Determination de la vitesse de propagation du son Title in German Pruefung von Beton.
Wn pulse velocity can be combined with the rebound hammer value for the strength evaluation of concrete. For determining the natural frequency of the ultrasonic pulse transmitted through the material.
Two pieces are required. Accessories Testing heads probes The standard 50 kHz transmitter and receiver heads are supplied with the tester. The measurement of pulse velocity can be used for the determination of the uniformity of concrete, the presence sn cracks or voids, changes in properties with time and in the determination of dynamic physical properties.
Search all products by. After traversing a known path length in the concrete, the pulse of vibrations is converted into an electrical signal by a 125044-4 tranducer and electronic timing circuits enable the transit time of the pulse to be measured.

The meter features a very accurate measurement of the transit time. Different heads are available with different nominal working frequency, 24 and kHz which is the usual range for normal concrete: It specifies a method for the determination of the velocity of propagation of pulses of ultrasonic longitudinal waves in concrete.

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.
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. Annexes to this standard provide information on the determination of pulse velocity, factors influencing pulse velocity measurements, and the correlation of pulse velocity and strength.
A pulse of longitudinal vibrations is produced by an electro-acoustical transducer held in contact with one surface of the concrete under test.
