Cygnus - Model 4+ -General Purpose Multi-Mode Ultrasonic Thickness Gauges
The Cygnus 4PLUS is a small and tough multi-mode ultrasonic thickness gage which features an A-scan display, simple to use sequential data logging and manual and automatic gain control. Designed for the harshest of environments, with a simple to use keypad, intuitive menus and a color LCD display which can be viewed in all lighting conditions.
The twin shot injection moulded enclosure has a soft but durable TPE outer skin which is comfortable to hold and protects against bumps while the hard internal shell offers maximum strength and environmental protection certified to the demanding US MIL STD 810G standard.
The unit still relies on Multiple-Echo to provide simple and accurate measurements, with the added benefit of Echo-Echo and Single-Echo using twin crystal probes for extreme corrosion. Echo-Echo for measurements on painted metals but with heavy back wall corrosion / pitting and Single-Echo for measurements on uncoated surfaces with heavy front face and/or back-wall corrosion and attenuative materials such as cast metals or plastics / composites.
- Multiple-Echo for reliable, accurate through coating measurements
- Single-Echo and Echo-Echo measuring modes with twin crystal probes for extreme corrosion and back wall pitting
- A-scan display
- Manual and automatic gain control
- MSI™ (Measurement Stability Indicator) used in Single-Echo and Echo-Echo measurement modes
- Simple linear data logging
- Large bright color LCD screen with back light
- Deep-coat mode, measure through coatings up to 20 mm thick
- Wrist mountable
- Min/max measurement limit functions with visual and vibrate alert
- Intuitive easy to use menu
- Extremely rugged enclosure – shock and impact to US MIL STD 810G
- Environmental sealing to IP67 – US MIL STD 810G
- Cygnus echo strength bars to assist quick measurements
- Buttons integral with the TPE molding and designed for minimum 100,000 depressions.
Data Logging Key Features
- Versatile data logging which allows measurements and A-scans to be saved
- 5,000 measurement points (including A-scan) per record
- Records are saved to a removable SD card
- Selectable auto-log feature
- Records easily transferred via gage USB port to CygLink software where they can be exported to a .CSV file or a PDF report.
Multiple-Echo uses three back wall echoes and measures remaining metal thickness while ignoring coatings. All measurements are error checked using 3 return echoes to give repeatable, reliable results. Accepted by all major classification societies. Uses single crystal probes for linear accuracy (and no probe zero required).
Echo-Echo uses two back wall echoes and measures remaining metal thickness while ignoring coatings up to 0.04 inch (1 mm) thick using twin crystal probes for improved detection of back wall corrosion and pitting.
Single-Echo uses one back wall echo, measures remaining metal thickness on uncoated surfaces and is possibly helpful for areas with extreme front face or back wall corrosion and pitting. Effective on highly attenuative materials such as cast metals, plastics and composites.
MSI™ (Measurement Stability Indicator)This clever technique helps ensure only stable measurements are displayed in Echo-Echo and Single-Echo modes. Displayed measurements change color from red to green and vibrate alert to indicate a stable reading.
Flexible HandlingAlong with the wrist and neck straps supplied in the kit there is also an optional belt clip, offering a range of flexible handling solutions for all types of applications.
