Cygnus Launches NEW Range of Multi-Mode Ultrasonic Thickness Gauges

Cygnus Instruments Ltd, leading manufacturer of Multiple-Echo digital ultrasonic thickness gauges, unveils their latest range of surface instruments.

The new range of thickness gauges is launched following extensive customer engagement, working within industry standards and following careful and exhaustive design reviews.


Cygnus has now incorporated two additional measuring modes in to their latest range of thickness gauges. Single-Echo and Echo-Echo modes, both using twin crystal probes, can assist in obtaining measurements in areas of extreme corrosion or back wall pitting:

  • Single-Echo measuring mode – ideal for measuring uncoated surfaces with heavy front face and/or back-wall corrosion and attenuative materials such as cast metals, plastics and composites.
  • Echo-Echo measuring mode – used for measuring painted metals but with heavy back wall pitting for improved back wall detection.

The new range consists of 4 models offering an array of new features including: A-scan display; hands free units for climbing or rope access; simple sequential data logging; vibrate alert to warn the operator when the measurement is out of tolerance; and MSI™ (Measurement Stability Indicator).

MSI™ is both clever and simple. Used in Single-Echo and Echo-Echo modes, this trademarked technique samples returning echoes to ensure they are all identical. If the returning echoes are identical the display changes colour or format which indicates the reading is stable and reliable.

The Cygnus 4+ offers simple sequential measurements to be recorded and records up to 5,000 measurement points, including A-scans, and comes supplied with CygLink software.

CygLink is a Windows® application for PC’s running Windows 7 and above and is used for uploading data from a data logging gauge. The information can then be analysed, stored, reports can then be created and the data can be exported as a .pdf or .csv file.

While the new range from Cygnus offers many new features, the simple to use menu structure means that these new gauges are quick to learn and simple to use.

The new instrument enclosure has allowed Cygnus to achieve the tough American Military Standard MIL SPEC 810G for environmental protection. These new gauges will survive the harshest operating conditions including drop, vibration, dust and water ingress (IP67) together with low and high temperature cycling.
