Determination of ultrasonic pulse velocity Status: Annexes rn this standard provide information on the determination of pulse velocity, factors influencing pulse velocity measurements, and the correlation of pulse velocity and strength. The PULSONIC is used for measuring the velocity of ultrasonic pulses through a concrete section providing informations on cracks, voids, strength, and giving quick estimates of dynamic modulus of elasticity on site or in the laboratory.

Different dn are available with different nominal working frequency, 24 and kHz which is the usual range for normal concrete: The faster, easier way to work with standards.

A pulse of longitudinal vibrations is produced by an electro-acoustical transducer held in contact with one surface of the concrete under test.

You may find similar items within these categories by selecting from the choices below:. The meter features a very accurate measurement of the transit time.

This value can be insert in the dedicated menu of UPV tester combining a enn surface measurement with the deeper UPV transit time in order to obtain a more reliable and extended information. Accessories Testing heads probes The standard 50 kHz transmitter and receiver heads are supplied with the tester.

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. The measurement of pulse velocity can be used for the determination rn the uniformity of concrete, the presence of cracks or voids, changes in properties with time and in the determination of dynamic physical properties.

For determining the natural frequency of the ultrasonic pulse transmitted through the material.
