Benefits
- Multiple-echo, single-crystal
ultrasonic thickness gauge.
- Coatings
do not have to be removed - measures only the metal thickness.
- Accepted by major classification
societies.
- No grinding - minimum surface
preparation.
- Measures on rough corroded
surfaces.
- Speed, accuracy and reliability.
- No false readings - repeatable
results.
- Easy to use - minimum operator
training.
- Greatly reduced inspection time
and cost.
- Measures on metals and some
other materials.

Applications
-
 Metal thickness monitoring on
cranes, marine structures and conveying systems.
- Corrosion checks on ships'
shell plates, bulkheads and structures.
- Metal thickness safety checks
on steam and pressurized water systems, transportable gas
containers and compressed air systems.
- Systematic wall thickness and
corrosion monitoring of storage tanks and process vessels.
- Quality assurance metal
thickness checks.
- Maintenance and safety checks
on bridges and street lighting columns.

Cygnus
Multiple Echo Technology
With
multiple echo technology, readings are taken by
measuring the time delay between any three consecutive
backwall echoes. The time T1 (for coating thickness) is
ignored. The times T2 and T3 are equal to the time that
it takes for sound to travel through the metal. Only by
looking at three echoes can the measurements be made for
the metal thickness, where T2 = T3. |
