PHASCAN- Ultrasonic Phased Array Flaw Detector
PHASCAN portable ultrasound Phased Array Flaw Detector is a phased array inspection equipment developed for professional technician use by Doppler. The PHASCAN is designed for powerful detection, capable of a variety of scanning and focus modes which offers excellent detection reliability.
A PHASCAN unit makes use of a universally recognisable, friendly user interface, which is simple to operate. Combined with Doppler (or other) phased array probes it is the perfect device for solving a variety of complex problems whilst offering a cost saving in testing hardware.
Applications
Applications Include:
- Pipeline Weld Inspection
- Corrosion Mapping
- Aerospace and Composite Testing.
Overview
(1) The PHASCAN has 32/128 Pulser/Receiver channels for Phased Array. There is also high-performance TOFD detection using dual independent channels
(2) Calibration is very convenient to implement and can be verified for each beam.
(3) An Embedded focal law calculator allows:
- 4 modes of scanning: linear, sectorial, depth and static.
- True Depth, sound path, projection, and focal plane with 4 variations of focus types
- Display modes: A/S/B/C
(4) Multiple group for parallel scanning- which is the equivalent of multiple instruments working simultaneously.
(5) Negative square-wave emission, with resolution up to 2.5ns, PRF up to 20KHz.
(6) 10.4'' TFT LCD colour touch screen, with resolution 800*600 pixel.
Features
(1) Convenient setup wizard
- Materials selection, with a velocity database
- Workpiece configuration for flat or curved surfaces.
- Library of probes and wedges for fast selection as well as user-defined options
- Multiple options for scanning modes and depth are available with the same probe simultaneously
(2) Accurate calibration
- Every beam is a single channel detector, ensuring calibration of each channel.
- Interactive menus allow operators to quickly adjust the velocity, wedge delay and sensitivity calibration.
(3) Powerful data analysis
- Measurement and Reference cursors can be used to quantify defects that are found and this information can be used to generate reports.
- Interactive analysis in all modes: A, B, S and C-scan. Defect analysis is, therefore, more precise.
- All measurement results are obtainable online. An off-line analysis is performed on the saved complete A-scan.
(4) Excellent focus imaging
- Precise image resolution
- Angle accuracy of up to 0.1 °.
- Focus type can be set which more clearly shows defects
