Main applications Standard UPV measurement with incorporated oscilloscope. Very often the transit time only is not enough to identify disomogeneities and 1250-44 damages as for example microcracking of concrete which are, on the contrary, well located with this technique by properly processing the acquired waveforms.

For determining the natural wn of the ultrasonic pulse transmitted through the material. Take the smart route to manage medical device compliance. 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.

Model Nominal frequency kHz approx. The unit includes an excel spreadsheet for the acquisition of the waveform on the PC for further elaborations.

Determination of ultrasonic pulse velocity Status: Nominal frequency kHz approx. The meter features a very accurate measurement of the transit time. It can also be used for estimating times for formwork striking. Different heads are available with different nominal working frequency, 24 and kHz which is the usual range for normal concrete: Reinforcement, Velocity measurement, Test equipment, Prestressed concrete, Flaw detection, Strength of materials, Testing conditions, Reinforced concrete, Transducers, Modulus of elasticity, Poisson ratio, Sonic testing, Error correction, Ultrasonics, Ultrasonic testing, Cement and concrete technology, Concretes, Accuracy, Correlation methods, Non-destructive testing.

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.

The pulse velocity can be combined with the rebound hammer value for the strength evaluation of concrete. It is possible to use our digital test hammer to obtain the avarage value of rebound number. 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.

Accessories Testing heads probes The standard 50 kHz transmitter and receiver heads are supplied with the tester. The PULSONIC is used for 1250-44 the velocity of ultrasonic pulses through a concrete section providing informations on cracks, voids, strength, dn giving quick estimates of dynamic modulus of elasticity on site or in the laboratory.
