Cygnus DIVE Underwater Gauge

With its bright, very large, AMOLED display the Cygnus DIVE is simple to operate, providing accurate and reliable thickness measurements, underwater. Depth.....
  • 300 m depth rated
  • Wrist-mountable, giving the diver a free hand
  • A-Scan (selectable)
  • Data logging - stores 5000 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 20 mm thick
  • Single-Echo - for use on extreme corrosion, anchor chain links and some plastics
  • MSI™ Measurement Stability Indicator - exclusive to Cygnus, confirms a stable reading in single echo mode
  • HelmetView™ - optional remote display.
Display 2.8” quarter VGA colour AMOLED (320 x 240 pixels)
Large clear thickness measurement (15 mm high numbers), viewable from all angles
A-Scan display with automatic X axis
Battery level, signal strength, probe type, velocity
Measurement mode and units indication
Battery Single 3.6V Li-ion 8.2 W battery
11 hours continuous measurement
Low battery warning ‘alert’ message
Measurement Modes                                 Multiple echo (three back-wall echoes) using Single Crystal (zero-degree) probes automatically ignores surface coatings and measures only metal thickness
Single echo (first back-wall echo) using Twin Crystal probes
Deep Coat In Multiple Echo mode, allows measurement to be made through thicker coatings of suitable materials of up to 20 mm thick
Accuracy ±0.1 mm (±0.004”) or 0.1% of thickness measurement, whichever is greatest, when calibrated in accordance with Cygnus Instruments calibration procedure
Probes Single Crystal probes:
2.25 MHz 13 mm (standard) S2C
2.25 MHz 19 mm S2D
3.5 MHz 13 mm S3C
5.0 MHz 6 mm S5C

Twin Crystal probes:
2.0 MHz 13 mm x2 (for some plastics e.g. outfall pipes) T2C
5.0 MHz 8 mm x2 (standard) T5B
Probe Cables Double outer jacket in tough PU.  Coloured yellow for easy locations underwater.  Coiled for ease of use.  Fischer S105 series connectors.
Measurement Ranges Multiple Echo (through coatings) with Single Crystal probes:
2.25 MHz = 3.0 to 250 mm
3.5 MHz = 2.0 to 150 mm
5.0 MHz = 1.0 to 50 mm

Single Echo with Twin Crystal probes:
5.0 MHz = 1.5 to 50 mm in steel
2.0 MHz = 2.5 to 150 mm in steel
Measurement Resolution Multiple Echo with Single Crystal probes - 0.1 mm or 0.05 mm
Single Echo with Twin Crystal probes - 0.1 mm or 0.01 mm
Measurement Units mm or inches
Probe Zero Fully automatic probe zeroing for all probes types
V-Path Correction Automatic V-Path correction for all Twin Crystal probes
Velocity Range 2000 to 9000 m/s in 1 m/s setps
Pulser Twin channel 70 V spike pulser
Receiver / Amplifier 10 MHz bandwidth, 120 dB range, automatic TCG
60 MHz measurement time-base
Data Logging One-handed automatic logging of stable measurements.  Capacity for up to 5000 points including 640 point A-Scan data.
Data Output RS-485 single pair, half duplex for surface connection
Computer Software CygLink v4 allows remote logging and viewing of A-Scan graphs.  Survey and report generation to PDF file. Graphic analysis of data and statistical calculations.  Designed for Windows 7 and Windows 8.
