Setting standards of performance and reliability

For over 20 years the Powerscan name has meant exceptional performance with class leading design. The latest developments in amplifier and pulser technology deliver higher levels of near surface resolution, penetrating power and excellent signal to noise ratio.

High Performance with Total Control

The Powerscan delivers high performance and advanced features, yet our engineer's experience in user interface design has ensured it is easy and quick to use. The acknowledged ease of use of the previous Powerscan generation has been enhanced with the menu navigation key, providing easy access to functions. The menu structure has been designed to guide the user through their task with operation quickly becoming second nature.

Robust and Reliable

Sonatest's reputation for robust design and proven reliability is an important aspect of flaw detector ownership. Down time is expensive and should be minimised to ensure maximum productivity. The Powerscan is constructed to high standards using Xenoy plastics and sealed to IP67, giving excellent water resistance so it can withstand the tough environments in which operators work.

The Powerscan comes with 2 years warranty, extendable to 5 years with Sonacover, and a worldwide service network.

High Visibility Display

For any flaw detector the display is a crucial element. The Powerscan has a colour transflective TFT display as standard, providing high visibility at any light level. The choice of colours for menus and waveform display enhance clarity, with the LCD simulation mode giving direct sunlight readability. The TFT does not suffer the typical black out problems or temperature limitations of LCD giving full weather capability. The new Full Screen mode maximises the A-scan area to improve readability further whilst testing and its fast response and peak capture functionality ensure any indication is clearly displayed, even if it only appears for one cycle of the 500Hz PRF.

High Power - Low Noise

When testing large forgings and castings high power and low noise are essential. The Powerscan's high power 450 Volt square wave pulser and ultra low noise amplifier achieve an excellent signal to noise ratio. This class leading performance enables testing of very attenuative or large components. The 20 metre range and calibrated delay makes the testing of long shafts simple and extremely accurate, while the ability to recall 100 previous waveforms allows quick evaluation of defect growth.

Split DAC & AVG

Split DAC and AVG (DGS) are advanced amplitude defect sizing tools necessary for testing thick welds and large castings and forgings. Due to the decay of the curves it is not possible to evaluate a defect signal on long ranges, where the amplitude is too low. Split DAC/AVG splits the time base into 3 regions, where the height of the curve and amplifier gain is automatically increased by reference
+12dB and reference +24dB when the curve drops to 20% height to re-position at 80% height.

By using this feature it is then possible to inspect the whole region at once without the need to manually increase the curve height or reference gain, in accordance with EN583-2 Sensitivity and Range Settings.

Application Areas

Railway Axle Testing
Long Shafts
Large Castings & Forgings
Thick Attenuative Materials e.g. composites
Rolling Mill Rolls
Turbines

SDMS (Optional Sonatest Data Management Software)

This Windows based data management tool allows the user to interface a Sonatest digital flaw detector with a PC. The software uploads and downloads panel settings and A-scans, which can also be copied and pasted into Word for customised reporting. Thickness readings can be transferred directly into Excel with the ability to produce charts for B & C-Scans, colour 3D mapping etc.
