Nominal frequency kHz approx. 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.

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

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.

It specifies a method for the determination of the velocity of propagation 122504-4 pulses of ultrasonic longitudinal waves in concrete.

The meter features a very accurate measurement of the transit time. Two pieces are required. After traversing a known path length in the concrete, the pulse of vibrations is converted into an electrical signal by a second tranducer and electronic timing circuits enable the transit time of the pulse to be measured.

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.
