CYGNUS 4 PLUS GENERAL PURPOSE

MULTI-MODE ULTRASONIC THICKNESS GAUGE
The Cygnus 4+ General Purpose thickness gauge is a light, tough multi-mode thickness gauge. It features a sunlight readable display with Live A-scan, intuitive menu and sequential data logging for easy reporting and analysis. Used with Cygnus High Temperature Probe, the Cygnus 4+ can measure remaining wall thickness of high-temperature, in-service assets without shutdown or isolation. The C4+ UTG is ideal for plant maintenance, civil engineering, ship inspections, oil and gas facilities as well as high-temperature, in-service thickness surveys across refining, oil and gas, energy and process sectors.

Probes

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

Variety of Cygnus INOX Probes

  • Stainless steel SINGLE CRYSTAL probes, used in multiple-echo mode, include replaceable membranes for long life, require no zeroing and have a high linear accuracy.
  • Stainless steel TWIN CRYSTAL probes, used in echo-echo and single-echo modes, have improved measurability on extreme back wall corrosion and pitting.
  • Probes for use with the Cygnus 2+, 4, 4+ and 6+ gauges are fitted with a BNC or Lemo 00 connector.

Single Crystal Probes

Twin Crystal Probes

High Temperature Probe

Twin element ultrasonic probe designed for high-temperature, in-service thickness measurements and corrosion surveys across oil & gas, refining, energy and process sectors.

  • No cooling period required – reducing inspection time and facilitating effective measurement
  • For use on hot surfaces up to 300°C
  • Measures remaining wall thickness from 1.5 to 250 mm (0.05 to 9.8 inch) – depending on temperature and material.
