Masterscan 380


Masterscan 380 -
Sonatest Ltd manufacture Digital Flaw Detectors that set standards in performance and reliability. The Masterscan 380M employs latest developments in amplifier and pulser technology, delivering higher levels of near surface resolution, penetrating power and excellent signal to noise ratio. Typical applications are thin walled components, turbine blades, spot welds, power generation (including EMATs), large castings and forgings.

Unique ActiveEdge™ Transmitter Technology
The Masterscan series of flaw detectors have an ActiveEdge™ transmitter that drives the pulse on both the leading edge and trailing edge. This development enhances near surface resolution and removes the need for sensitivity reducing damping resistors. The added control achieved by the design helps the Masterscan optimise characteristics for a wide range of transducers, reaching even higher performance.

Robust and Reliable
Sonatest’s reputation for robust design and proven reliability is an important aspect of flaw detector ownership,  ensuring maximum productivity. The Masterscan 380M is constructed to high standards using Xenoy plastics and sealed to IP67, resulting in excellent water resistance, withstanding the toughest application environments.

High Performance with Total Control
The 380M 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 Masterscans 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.

Systems Integration
The 380M has additional features designed to integrate with automated test systems. The high 5 KHz PRF, interface trigger (IFT) and back wall echo attenuation (BEA) make it an ideal flaw detector for many system applications that require portability or the need to support manual inspection with the same unit. Proportional outputs and alarms update at the PRF, so high speed testing is easily handled, and full remote control via USB interface provides fast set up changes.

High Visibility Display
For any flaw detector the display is a crucial element. The Masterscan 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.

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.
