Cygnus DIVE Underwater Gauge

Wrist-Mountable Underwater Thickness Gage

0 out of 5 based on 3 customer ratings
(3 customer reviews)

With its bright, very large, AMOLED display the Cygnus DIVE is simple to operate, providing accurate and reliable thickness measurements, underwater.  Depth rated to 984 ft (300 metres).

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 gage 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 Instruments builds all of its equipment in the UK using only genuine and original parts and components – including Lemo® Connectors and Peli® Cases.

Features

  • 984 ft (300 m) depth rated
  • Wrist-mountable, giving the diver a free hand
  • A-Scan (selectable)
  • Data logging – stores 5,000 measurements and A-Scans
  • “Auto-Log” – no log button to press
  • AMOLED display, easy viewing from all angles for diver and camera
  • Multiple-Echo, error- checked measurements through coatings up to 0.8 inch (20 mm) thick
  • Single-Echo – for use on uncoated surfaces with heavy back-wall corrosion/ pitting
  • MSI™ Measurement Stability Indicator – exclusive to Cygnus, confirms a stable reading in Single-Echo and Echo-Echo modes
  • Echo-Echo – for use on painted surfaces with heavy back-wall corrosion/ pitting (through up to 0.02 inch (0.5 mm) paint)
  • HelmetView™ – optional remote display.

Deep Coat In Multiple-Echo mode, allows measurement to be made through thicker coatings of suitable materials of up to 0.8 inch (20 mm) thick
Accuracy ±0.004 inch (±0.1 mm) or 0.1% of thickness measurement, whichever is greatest, when calibrated in accordance with Cygnus Instruments calibration procedure
Probe Cables
Double outer jacket in tough PU
Colored yellow for easy locations underwater
Coiled for ease of use

Measurement Ranges
Multiple-Echo (through coatings) with Single Crystal Probes:
  • 2.25 MHz = 0.120 – 10 inch (3 – 250 mm)
  • 3.5 MHz = 0.080 – 6 inch (2 – 150 mm)
  • 5 MHz = 0.040 – 2 inch (1 – 50 mm)
Echo-Echo with Twin Crystal Probes:
  • 5 MHz = 0.160 – 2 inch (4 – 50 mm in steel)
  • 2 MHz = 0.235 – 2 inch (6 – 50 mm in steel)

  • 5 MHz = 0.080 – 4 inch (2 – 100 mm in steel)
  • 2 MHz = 0.120 – 6 inch (3 – 150 mm in steel)

Topside Repeater with Video Overlay

Allows real-time thickness measurements and calibration settings to be overlaid on the dive monitor screen. Also supplied with a hand held repeater unit:

  • Measurements superimposed on to a composite PAL or NTSC video signal
  • Overlay can be re-positioned anywhere on the screen
  • Measurements and locations recorded on the survey video.

 

Surface Repeater

The Cygnus DIVE can be connected to a laptop on the surface running CygLink software. This can then be used to log readings and control gauge settings, for example the velocity of sound. Reports and graphical analysis can then be produced and saved.

 

HelmetView™

Developed by Cygnus for divers in black or limited visibility water. The small remote OLED display is mounted just in front of the lens on the diver’s helmet. With adjustable brightness, the thickness measurement is clearly visible to the diver. When auto-log is being used, the HelmetView™ display will indicate when the reading is logged.

Data Logging

Up to 5,000 measurements and A-Scans can be stored. The “Auto-Log” feature saves each stable measurement meaning the diver doesn’t have to press a button every time a readings needs to be logged. Supplied with CygLink software.

  1. 5 out of 5

    :

    We used the 5MHz dual crystal as it gave the best results on the pitted steel we found on the many corroded ships hulls where we tried the UT gauge. The DIVE was reliable, very easy to use, has simple menu system and displays. The logging function was essential as we only had 13 minutes on the wreck each day; I could make lots of measurements and figure out the answer back home in post processing, we also didn’t have to write anything down or think too much as thinking isn’t so easy in 40m water with the effects of narcosis!

    We have used the equipment with very good results on a job so far.

  3. 5 out of 5

    :

    Regarding the MK-2 this has been working very good and we did over 1.000 readings with the same battery on two different days; we are completing a serial of surveys on pontoon ferries with a total of 4,000 readings and so far we are very happy with the device performance.
