Multi Mode Ultrasonic Thickness Gauge

NEW GENERATION OF CYGNUS MULTI-MODE THICKNESS GAUGES

The NEW Cygnus 4+ ultrasonicthickness gauge is small, tough and accurate.

Designed for the harshest of environments, with a simple to use keypad and intuitive menus and a colour LCD display which can be viewed in all lighting conditions.

The twin shot injection moulded enclosure has a soft but durable TPE outer skin which is both comfortable and extremely durable, while the Inner shell IS strong, keeping the electronics totally sealed, from the outsnde world.

The unit still relies on Multiple-Echo to provide simple and accurate measurements, with the added benefit of Echo-Echo and Single- Echo using twin crystal probes for extreme corrosion. Echo-Echo

for measurements on painted metals but with heavy back wall corrosion / pitting and Single-Echo for measurements on uncoated surfaces with heavy front face and/or back-wall corrosion and attenuative materials such as cast metals or plastics / composites.

Features

  • Multiple-Echo for reliable, accurate through coating measurements
  • Single-Echo and Echo-Echo measuring modes
  • Large bright colour LCD screen with automatic LCD back light
  • Min/max measurement limit functions with visual and vibrate alert
  • Extremely rugged enclosure - shock and impact to MIL STD 810G
  • Environment sealing to IP67 - MIL STD810G
  • Deep-coat mode, measure through coating up to 20 mm thick
  • Cygnus echo-strength bars assist thickness measurements in Multiple-Echo mode TPE over moulded enclosure
  • Buttons designed for minimum of 100,000 depressions
  • Fully sealed battery compartment (contains any leaking battery fluids)
  • A-scan display
  • MSI TM (Measurement Stability Indicator) for Single-Echo and Echo-Echo modes
  • Sequential data logging
  • Automatic probe recognition for S2C and twin crystal probes.

MULTI-MEASURING MODE

Multiple-Echo uses three back wall echoes and measures remaining metal thickness while ignoring coatings. All measurements are error checked using 3 return echoes to give repeatable, reliable results. Accepted by all major classification societies. Uses single crystal probes for linear accuracy (and no probe zero required).

Echo-Echo uses two back wall echoes and measures remaining metal thickness while ignoring coatings up to 1 mm (0.04") thick using twin crystal probes for improved detection of back wall corrosion and pitting.

Single-Echo uses one back wall echo, measures remaining metal thickness on uncoated surfaces and is ideal for areas with extreme front face or back wall corrosion and pitting. Effective on highly attenuative materials such as cast metals, plastics and composites.

CYGLINK SOFTWARE

CygLink is a Windows® application which is used to transfer information from the Cygnus 4+ thickness gauge to a computer. The information can then be used to create reports which can be analysed, stored and exported.

MSI TM (MEASUREMENT STABILITY INDICATOR)

This clever technique helps ensure only stable measurements are displayed in Echo-Echo and Single-Echo modes. Displayed measurements change colour from red to green and vibrate alert to indicate a stable reading.

DATA LOGGING

  • Data logging record format using linear based measurements
  • 5,000 measurement points (includingA-scan)per record (records quantity dependent on SD card capacity)
  • The user can log 'obstructed' and 'no reading' if no thickness measurement can be obtained
  • There are menu functions to: step back; retake-last; stop and resume logging; review measurements; protect records; delete records
  • Data logging screen shows average, highest and lowest thickness measurement values from the record
  • Records can have optional minimum and reference thickness values set which are used to highlight logged measurements, i.e. red if under min, green if between min and ref.
  • Records are saved to removable micro-SD card
  • Records are easily transferred to a computer via USB and CygLink software where they can be examined, saved, turned into a PDF report or exported to a CSV file.

CYGNUS PROBES AND CABLES

Stainless Steel INOX Twin Crystal Probes: Used in Echo-Echo and Single-Echo modes and focussed ultrasound beam with improved measurability on extreme back wall corrosion and pitting.

Stainless Steel INOX Single Crystal Probes: The INOX probes have an updated ergonomic design and an easier to read frequency, identification and serial numbering. All frequencies of INOX probes have a black face and a colour coding system to identify probe frequencies. Used in Multiple-Echo mode, these probes require no zeroing, have a high linear accuracy, are ideal for general thickness gauging and on pipes and have replaceable wear membrane for long life.

Cygnus Cables: Using standard industry connectors the probe lead uses a custom made over moulded cable that offers superior flexibility and resistance to oils and ultraviolet light. The cable will not stiffen after exposure to ultraviolet light.

STANDARD KIT CONTENTS

Cygnus ultrasonic thickness gauge; padded carry case; operating manual; adjustable neck strap and loops; wrist strap; accessory pouch; spare membranes; surface and membrane couplant; test block; 3 xAA batteries; data transfer cable; SD card; optional Krusell® belt clip and attachments accessory.
