The Powerscan 450P Ultrasonic Flaw Detector delivers high performance and advanced features, via enhanced menu navigation keys, providing easy access to functions. The menu structure has been designed to guide the user through their task with operation quickly becoming second nature. The latest developments in amplifier and pulser technology deliver higher levels of near surface resolution, penetrating power and excellent signal to noise ratio. NDT Application areas include Railway Axle Testing, Turbines and large Castings and Forgings.
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.
The Powerscan 450P is constructed to Sonatest’s proven standards for robust deisng and proven realiability, sealed to IP67, giving excellent water resistance so it can withstand the tough environments in which operators work. The Powerscan 450P 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 Powerscan 450P ultraonsic flaw dector is delivered with 2 years warranty, extendable to 5 years with Sonacover, and a worldwide service network.
