Sonatest Railscan 125


Category: Tag:


Designed specifically for Rail Testing, the Railscan 125R rises to the demanding challenges set by this environment for NDT and it’s operators.
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: Supporting 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 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 flawOptional Sonatest Data Management Software 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.

Railscan 125 Specification
Test Range: 0 – 5mm (0.2in) up to 0 – 10000 mm (400 in.) at steel velocity. Variable in 1mm & 10mm steps.

(single gate) Mode 4: Trigonometric display of beam path, surface distance and depth of indication, curve surface correction and X-OFFSET for probe index. Half skip indication on screen. Mode 5: T-Min mode for holding minimum thickness reading. Resolution: 0.01mm (0.001in) for distance measurement or 1% FSH for amplitude measurement. Large display of measurement at the top of A-Scan display. Measurement mode selectable between peak and flank. Thickness Logging: Storage for 8000 thickness readings configured either by Block/Location/Number mode or pre-programmable work sheets in sequential mode. Readings can be exported to MS Excel using optional SDMS software. DAC: DAC defined by up to 10 points and digitally drawn on screen. DAC curves meet requirements of EN 1714, JIS and ASME standards, selectable between -2, -6, -10, -12 and -14dB. Amplitude read out selectable between % DAC or relative dB
