Ultrasonic Thickness Gauges - Cygnus
Subsea Thickness Gauges
NEW Cygnus Underwater
Ultrasonic Thickness Gauge
Specifically designed for divers undertaking ultrasonic thickness measurement (UTM) of underwater structures, the Cygnus Underwater has been built to withstand harsh subsea environments while providing quick and accurate metal thickness measurements through coatings or heavy corrosion. This diver-held gauge is simple to operate using 3 function keys, an intuitive menu and a large LCD display – highly visible, even in low-visibility waters.
Three Selectable Measuring Modes
Multiple-Echo mode uses three error checked back wall echoes to provide the most reliable and accurate remaining thickness measurements, with no need to remove coatings (up to 20mm/0.8 in thick).
Single-Echo mode is ideal for measuring uncoated metals with heavy front and/or back-wall corrosion. Also effective on many cast metals, plastics and composites.
Echo-Echo mode works best for measuring heavily corroded metals through thin coatings of up to 1mm/0.04in thick, ideal for measuring coated metals with heavy back wall corrosion.
Exclusive to Cygnus, Measurement Stability Indicator (MSI™) ensures stable and therefore reliable measurements are displayed in Echo-Echo and Single-Echo DEPTH modes.
FEATURES
- 3 measuring modes for levels of corrosion, various materials and through-coat measurements
- Depth sensor – live depth display providing the diver with an accurate depth indicator
- Live A-Scans aid visual measurement verification
- Extremely Simple-to-Use with 3 function keys and up to 4 screens
- Comprehensive data-logging: linear and grid
- Deep Coat function ignores thick coatings
- RTC (Real Time Clock) for tagging date/time on measurement points
- Auto-set Gain to optimise the probe’s gain settings for optimal performance
- Multiple Echo Mode to verify accurate through-coat measurements as specified by Class Societies
- Measurement Stability Indicator (MSI™) verifies stable and therefore reliable measurements
- Available in STD, PLUS and PRO variants with upgradeable options, e.g. Topside Repeating and Data Logging
