Ultrasonic Pulse Velocity And Pulse Echo Testing Of Concrete

Standards: EN 12504-4, ASTM C 597-02, BS 1881 Part 203, ISO1920-7:2004

Structural defects cause serious damages and collapses. Ultrasonic testing provides information on the strength and uniformity of concrete, rock, composites, ceramics, wood, epoxy, refractory materials and can be used to detect and localize voids, pipes, cracks and defects.

The pulse velocity in a material depends on its density and its elastic properties which in turn are related to the quality and the compressive strength of the concrete. It is therefore possible to obtain information about the properties of components by sonic investigations.
 
Proceq offers the most versatile instrument for ultrasonic testing of concrete.
 
Ultrasonic Pulse Velocity - Pundit Lab
 
Measurement performance; Optimized pulse shaping, automated transmission settings for optimum performance and a range of new, more powerful transducers ensure accurate, stable measurements.
 
Integrated waveform display; Allows analysis of the received signal and manual triggering directly on the instrument.
 
On-line data acquisition; Full remote control of all transmission parameters, data logging function and functionality that turns your PC into an oscilloscope.
 
USB interface and data analysis software; Data analysis and export to third party programs.
 
Open interface; Control Pundit Lab using third party software such as LabVIEW.
 
Pundit Lab consisting of: Display unit, 2 transducers (54kHz), 2 BNC cables 1.5 m, couplant, calibration rod, battery charger with USB-cable, 4x AA(LR6) batteries, data carrier with software, documentation and carrying case.
 
Ultrasonic Pulse Velocity - Pundit Lab Plus
 
Integrated gain stage; Removes the need for an external amplifier when using exponential transducers and long cables.

Compressive strength measurement; Conversion curves for strength estimation can be created in the software and uploaded to the instrument to give instant strength estimations on site.
 
Combined estimates with rebound hammer; SONREB curves may also be uploaded onto the instrument for improved compressive strength estimates in combination with rebound hammer measurements.
 
Time stamp; A real time clock has been integrated to provide a time stamp to every measurement recorded.
 
Review list; Saved measurements may be reviewed directly on site without the need for a PC connection.
