Cygnus Dive Underwater Ultrasonic Thickness Meter

Cygnus Dive Underwater Ultrasonic Thickness Meter

Overview

The Cygnus DIVE is a robust, wrist-mountable ultrasonic underwater thickness gauge - providing an invaluable free hand while performing Ultrasonic Thickness Measurement (UTM) underwater. The large, bright display with Live A-scan is easily viewable by both the diver and his camera - even in the poorest visibility. With only two buttons to press, the gauge is very easy to navigate through an intuitive, user-friendly menu. Ideal for hull UTM inspection, civil engineering, marine structures and offshore platforms.

 

Key Features

  • Multiple-Echo mode for accurate, through-coat measurements as specified by Classification Societies
  • Single-Echo and Echo-Echo modes for heavily corroded metals with a thin or no coating
  • Deep-Coat function to ignore coatings up to 0.8" (20mm) thick
  • A-Scan display to assist with measurement verification
  • Optional Data Logging feature with Auto-Log - storing up to 5000 measurements including A-Scan data without pressing a button
  • MSI (Measurement Stability Indicator) verifies stable, reliable readings
  • Rechargeable Lithium-ion battery giving up to 10 hours continuous measurement
  • Optional remote display HelmetView, Topside Repeater and Cyglink surface display software

3 Versatile Measuring Modes

  • Multiple-Echo modes 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 0.8" / 20mm thick)
  • Single-Echo mode is ideal for measuring uncoated metals with heavy front and/or back wall corrosion. Also effective on a range of cast metals, plastics and composites.
  • Echo-Echo mode works for measuring heavily corroded metals through thin coatings of up to 0.04" (1mm) thick, ideal for measuring painted metals with heavy back wall corrosion.

Transducers

Variety of Cygnus INOX Transducers

  • Stainless steel SINGLE CRYSTAL transducers, used in multiple-echo mode, include replaceable membranes for long life, require no zeroing and have a high linear accuracy.
  • Stainless steel TWIN CRYSTAL transducers, used in echo-echo and single-echo modes, have improved measurability on extreme back wall corrosion and pitting. 

Cygnus INOX Transducers

Measurement Stability Indicator

Exclusive to Cygnus, MSI™ ensures stable and therefore reliable measurements are displayed in Echo-Echo and Single-Echo modes.

Cyglink Computer Software

CygLink is a Windows® based application for topside computer use to display continuous A-Scan output and measurement data. CygLink has the facility to log both data formats into a Survey file for report presentation, which can be emailed, exported as a PDF, or printed.

Options and Accessories

  • Topside Repeater (TSR) Remote Display Unit - The Cygnus Topside Repeater is a remote display unit connected to the DIVE gauge with an umbilical cable. It displays the thickness measurements at the surface in real-time during the survey.
  • Topside Repeater with Video Overlay - The Topside Repeater can also overlay the real-time thickness measurements on to a composite video signal, displaying it on the survey monitor screen. It will also then be recorded (if there is a video of the survey), showing exact locations and the thickness measurement for future reference.
  • HelmetView Display - This is a remote display with a fixing bracket for Kirby Morgan® Helmets that have an accessory mounting point. This is depth rated to 984 ft, and designed for use in situations with extremely poor visibility and ease of viewing by the diver.
