We are the experts… Cygnus was founded in 1983

Founded in 1983, Cygnus pioneered the digital Multiple-Echo technique. This technique has long since been the industry standard for through coating measurement of material thickness.

Driven by the need for a hand-held device, we successfully developed Multiple-Echo digital thickness gauges which measure metal thickness through protective coatings in a reliable and repeatable way. The range has recently been extended to include Echo-Echo and Single-Echo measurement modes to expand even further the usability of Cygnus gauges.

Simplicity through technology…

Cygnus gauges are all robust and simple to use. They are engineered to withstand the harshest environments.

New Innovation…

Our roots are in marine inspection services. Now building on strong foundations, Cygnus has entered a new phase of innovation. We are investing heavily in market research and product development. We believe in an entirely application-driven, user-focused approach. For this reason we put a huge emphasis on listening to customer requirements and feedback.

As a result of thousands of hours of research, development and continued investment, Cygnus has set and raised the standard for accurate thickness measurement devices, manufacturing gauges that are utilised in almost all industries including:

  • Ship hull surveys
  • Rope access surveys
  • Underwater inspections
  • Explosive environments.

These are just a few of the diverse industries in which Cygnus thickness gauges are used.

Remaining within the scope of using ultrasound for inspection, we have also developed the Hatch Sure, an ultrasonic hatch cover leak detector. Used predominantly for checking hatches on bulk carriers it also has many other applications e.g. weather-tight door testing.

Highest Quality…

Cygnus is an ISO-9001 accredited company. On account of this and our intrinsically safe certifications (BASEEFA and CSA), we are constantly being audited guaranteeing you the best quality products.

At Cygnus, high quality comes first and foremost.

Available with data logging, topside, HelmetView™ and twin crystal probe options.
MSI™ Measurement Stability Indicator - this is a feature exclusive to the Cygnus. When using the DIVE Gauge in Single-Echo and Echo-Echo modes, MSI™ confirms when a reading is stable by turning the thickness measurement numbers from red to yellow.

Cygnus Underwater Diver Hand-Held Underwater Thickness Gauge

underwater

The Cygnus Underwater is the original diver held subsea multiple echo Ultrasonic Thickness Gauge. It was designed for use by divers undertaking subsea maintenance and surveys 3 decades ago… and today it is still the industry standard.
The unit is depth rated to 300 metres and it provides an accurate metal thickness measurement through coatings up to 20mm thick. The bright LED display ensures easy viewing even in poor visibility conditions.
The Underwater Thickness Gauge is supplied ready to use as a complete kit with 2 rechargeable batteries in a protective carry case.

Cygnus ROV Mountable Multiple Echo Ultrasonic Thickness Gauge

ROV Mounted

Specifically designed for underwater remotely operated vehicles, Cygnus offer two dedicated ROV Mountable thickness gauges, the M5-ROV-2K - 2,000 m depth rated, and the M5-ROV-4K - 4,000 m depth rated. These mountable measurement gauges again benefit from the multiple-echo technology found in all our ultrasonic measuring devices. They are truly versatile and designed to measure metal thickness through coatings in the harshest operating conditions.
Dedicated software reveals the date, time and thickness readings on the surface which may be logged or stored. In addition, a Topside Repeater (TSR) is available providing the ability to present the thickness measurements remotely and overlay them on to a video signal. This permits the measurements to be superimposed on the ROV camera’s monitor screen.

Cygnus Heavy Duty

Heavy Duty

Cygnus Instruments have designed the Cygnus Heavy Duty ultrasonic thickness gauge for use in tough and demanding environments where a rugged construction is essential to accurately gauge corrosion measurement and determine metal thickness without having to remove protective coatings.
The Cygnus Heavy Duty is dirt resistant, dust resistant and water resistant. Its shock-proof construction takes into account the unstable environments in which corrosion thickness measurements and structural inspections are performed, resulting in a metal thickness gauge that is able to withstand accidental drops, bangs and knocks.
The Cygnus Heavy Duty is supplied ready to use as a complete kit in a protective carry case

Hatch Cover Testing

Hatch Cover

Sea water ingress is one of the major sources of damage to cargo which often results in expensive insurance claims. Cygnus Instruments designed the ultrasonic hatch leak detector to test for water leaks and weather tightness of cargo hatch covers and doors.
The Cygnus range of ultrasonic hatch cover testing equipment includes the Cygnus Hatch Sure.

Probes: Ultrasonic Single Crystal Probes / Ultrasonic Twin Crystal Probes

Ultrasonic Single Crystal Probes

Ultrasonic Single Crystal Probes :

Cygnus single crystal probes are for use with the gauge in Multiple-Echo mode to read through and ignore coatings.

These have one piezo-ceramic crystal. This crystal both sends and receives the ultrasound energy.

The S2C single crystal 2.25 MHz 13 mm probe is recommended for the majority of applications and can be used to read through coatings up to 20 mm thick with the gauge in Deep Coat mode.

Cygnus twin crystal

Ultrasonic Twin Crystal Probes

Cygnus twin crystal (dual element) probes are for use with the gauge in Single-Echo or Echo-Echo modes.

The probe face is divided into two: one semi-circle transmits the ultrasound energy and the other receives it back.

They have a hard wear face which will eventually wear down. The gauge will automatically "Zero” the probe to compensate for wear (until there is excessive wear when the probe should be replaced). The gauge will indicate when the probe needs changing with a warning message.

In Echo-Echo mode, up to 1 mm of coating can be read through and ignored. Single-Echo mode can only be used on bare surfaces or where coatings have been removed.

The T5B twin crystal 5 MHz 8 mm probe is recommended for the majority of applications in Single-Echo and Echo-Echo modes.
