Cygnus 2+ Hands Free

Ultrasonic Thickness Meter

The 2+ is a simple, versatile thickness meter designed for “hands free” operation; the unit employs an end-mounted display and three distinct measuring modes to measure the wall thickness of a variety of metals of any level of corrosion and pitting. This meter can also be used on a wide range of engineering materials such as plastics / HDPE etc.

Key Features of the Cygnus 2+ Hands-Free Meter

  • Echo-Echo and Single-Echo modes for heavily corroded metals
  • Multiple-Echo mode for the most accurate, through-coat measurements (as specified by Classification Societies)
  • Uses both single and twin crystal transducers
  • Deep Coat function ignores coatings up to 0.8 inch (20 mm) thick
  • “Hands free operation”: wrist, waist belt and harness mountable
  • MSI™ (Measurement Stability Indicator) verifies stable, reliable readings
  • Simple to use menu
  • Environmental sealing (water and dust proof) to IP67 – US MIL STD 810G
  • Highly ruggedized enclosure – shock and impact proof to US MIL STD 810G
  • One and two point calibration
  • Can be upgraded to 4+ or 6+ at an additional cost.

Three Versatile Measuring Modes

  • Multiple-Echo mode uses three (error-checked) back wall echoes to provide the most reliable and accurate remaining thickness measurements. Multiple echo automatically measures through coatings up to 0.8 inch (20 mm)
  • Echo-Echo mode works best for measuring heavily corroded metals through thin coatings of up to 0.04 inch thick, and is ideal for measuring painted metals with heavy back wall corrosion.
  • Single-Echo mode is ideal for measuring uncoated metals with heavy front and/or back-wall corrosion. This mode is also effective on a range of cast metals, plastics and composites
  • Measurement Stability Indicator (MSI™)
  • Exclusive to Cygnus, MSI™ ensures that stable and reliable measurements are displayed in Echo‑Echo and Single-Echo modes.

To compliment our ultrasonic thickness gages we offer a range of ultrasonic transducers. The performance of any ultrasonic thickness gage relies heavily on the transducer and its suitability to the material being measured. Therefore, selecting the right transducer is vital. All Cygnus’ transducers are made from stainless steel and have a hard wear face or a wear membrane to protect the transducer.

Variety of Cygnus INOX Transducer

  • 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.
  • Transducers for use with the Cygnus 2+, 4, 4+ and 6+ gages are fitted with a BNC or Lemo 00 connector.

5 reviews for Cygnus 2+ Hands Free

We were asked to test the New Cygnus UTM Instruments 2+ and 4+, using their single and twin crystals probes.

Tests carried out in our premises on specially prepared samples and in real working conditions on a 15 years old dry cargo ship of 10.000 M.Tns.
Both instruments, apart they are well designed, they proved to be fast and accurate.

The gauging confirmation through the new measuring experience of MSI System, was a pleasant surprise.

User-friendly with high analysis full coloured LCD screen and very easy menu.

The strong tight case together with the strong cable and its twin lemo locking connector give the immediate impression of the unit being very rugged.

Believe it or not in the company that I belong to, we have an old one Cygnus 2 (single crystal) since 1990 or less, we compare to other devises that we have and confiability of Cygnus is incredible, there are certain surface that other can not measure. And our Cygnus has not the possibility to calibrate but when we test with the test block always is correct.

Haven’t had it long (9 months) but seems reliable and robust, despite being an older model (MK3)
