For over 20 years the Railscan 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.
Designed specifically for Rail Testing
Network Rail (UK) procedure and approval Narrow Band amplifiers 2 and 5 MHz G1 +ve trigger, G2 -ve trigger, (0.6 second delay for monitoring rail bottom depth).
Long Battery Life
Latest Li-Ion technology 10-16 hours (brightness dependant) Quick re-charge in 3-4 hours
Walking Stick Compatibility
Sperry walking stick. Others (e.g., NRS bi-directional walking stick) Single-shot PRF for high speed multiplexing RS232 & USB outputs for custom software systems, (e.g. Sperry palmtop with GPS)
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 Railscan 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 Railscan comes with 2 years warranty, extendable to 5 years with Sonacover, and a worldwide service network.
High Performance with Total Control
The Railscan 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 Railscan 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.
High Visibility Display
For any flaw detector the display is a crucial element. The Railscan 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 indicationis clearly displayed, even if it only appears for one cycle of the 1 KHz PRF.
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.
