Sonatest Sitescan 150S Ultrasonic Flaw Detector

Setting standards of performance and reliability
For over 20 years the Sitescan name has meant highly reliable, technician focussed flaw detectors and the new range continues this tradition. From the 123W entry level model to the high specification 250S – ease of use, rugged construction and high quality amplifiers are key elements of the design. Typical applications are weld inspection, corrosion testing, small castings/forgings and lamination checking.

Advanced Defect Sizing Tools as Standard
Weld and pipe inspection are major applications for the Sitescan series and we have therefore equipped them with the latest software tools for defect sizing. The 123W has DAC, while the 150S and 250S have DAC, AVG, AWS and API sizing techniques. The use of integrated sizing software reduces analysis time and hence speeds inspection.

Multiple standard sizing techniques are essential for service companies working to different customer standards, especially as service work becomes more international and operators are required to work to different codes.

High Visibility Display
For any flaw detector the display is a crucial element. The Sitescan 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 maximizes 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 PRF.

High Performance with Total Control
The Sitescan 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 previous generation Sitescans 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 minimized to ensure maximum productivity. The Sitescan series 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.

Models in The Range
Based on the 123W the 150S has the same broadband amplifier enhanced with all the software features required to improve operator efficiency and accuracy. These includes standard sizing tools, advanced measurement modes, full screen waveform display, thickness reading memory and an automatic calibration feature.

Features:

• Colour Reference Feature
  • An A-scan from a known defect free component can be stored and recalled in a different colour to the live A-scan. This effectively means that defects are highlighted in a different colour to the natural reflectors, enabling quicker and more reliable defect detection.
• Flexible Measurement
  • Two independent bar monitor gates offer a range of measurement options for signal height or distance using either flank or peak triggering. The echo-to-echo mode gives through paint thickness readings while the G1-G2 mode allows accurate gate positioning for signals which are extremely close together. The TRIG function gives surface distance and depth when using angle beam transducers.
• Curve Surface Correction
  • When using angle beam transducers on a curved surface the Sitescan will calculate the surface distance and depth of defect, taking into account the internal or external radius.
• Flaw Sizing
  • Automatic flaw sizing using DGS/AVG, AWS D1.1, API 5UE, speeds reporting of defect acceptance or rejection.
• Help Facility
  • ance. Full instructions for all functions are clearly displayed. A very useful function for multi-disciplined technicians who use a variety of NDT techniques and do not use the Sitescan on a day-to-day basis.
• Full Screen A-scan
  • In full screen mode the A-scan fills the display improving visibility.
• Fast Set Up Screen
  • The split screen mode enables fast set up and overview of basic parameters.
