It specifies 125044- method for the determination of the velocity of propagation of pulses of ultrasonic longitudinal waves in concrete.
The unit includes an excel spreadsheet for the acquisition of the waveform on the PC for further elaborations.
The measurement of pulse velocity can be 1504-4 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.
Nominal frequency kHz approx. For determining the natural frequency of the ultrasonic pulse transmitted through the material. Find Similar Items This product falls into the following categories.
Ultrasonic pulse analyzer
Different heads are available with different nominal working frequency, 24 and kHz which is the usual range for normal concrete: Specification for testing machines BS EN 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 1254-4 ultrasonic longitudinal waves in hardened concrete, which is used for a number of applications.
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.
Supplied with hard plastic carrying case. It can also be used for estimating times for formwork striking. The pulse velocity can be combined with the rebound hammer value for the strength evaluation of concrete.
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. Main applications Standard UPV measurement with incorporated oscilloscope.
Customers who bought this product also bought BS EN 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.
