After traversing a known path length in the concrete, the pulse of vibrations is converted into an electrical signal by 12540-4 second tranducer and electronic timing circuits enable the transit time of 125044 pulse to be measured. Take the smart route to manage medical device compliance.
Two pieces are required. Overview Product Details 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.
Testing equipment for the construction industry – CONTROLS
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.
Also suitable for determining the Dynamic Modulus of Elasticity.

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 125504-4 of applications.
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. Measurement of the Attenuation of the Transmitted Energy. The unit includes an excel spreadsheet for the acquisition of the waveform on the PC for further elaborations.
Different heads are available with different nominal working frequency, 24 and kHz which is the usual range for normal concrete: Find Similar Items This product falls into the following categories.

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.
A pulse of longitudinal vibrations is produced by an electro-acoustical transducer held in contact with one surface of 125044-4 concrete under test. Model Nominal frequency kHz approx.
Nominal frequency kHz approx. 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.
Very often the transit time only is not enough to identify disomogeneities and little damages as for example microcracking of concrete which ne, on the contrary, well located with this technique by properly processing the acquired waveforms.
Accessories Testing heads probes The standard 50 kHz transmitter and receiver heads are supplied with the tester. Please download Chrome or Firefox or view our browser tips. The pulse velocity can be combined with the rebound hammer value for the strength evaluation of concrete. It specifies a method for the determination of the velocity of propagation of pulses of ultrasonic longitudinal waves in concrete. Learn more about the cookies we use and how to change your settings.
