Ultrasonic Thickness Gauging
Ultrasonic thickness gauging is a widely used non-destructive test technique for measuring the thickness of a material from one side. It is fast, reliable, and versatile, and unlike a micro meter or calliper it requires access to only one side of the test piece.
Virtually any common engineering material can be measured ultrasonically. Ultrasonic thickness gages can be set up for metals, plastics, composites, fiberglass, ceramics, and glass. On-line or in-process measurement of extruded plastics and rolled metal is often possible, as is measurement of individual layers or coatings in multilayer fabrications. Liquid levels and biological samples can also be measured. Ultrasonic gauging is always completely non-destructive, with no cutting or sectioning required.
The three most common formats are known in the NDT world as A-scan, B-scan and C-scan presentations. Each presentation mode provides a different way of looking at and evaluating the region of material being inspected.
Some of the advantages of ultrasonic thickness gauging:
- Non-destructive technique
- Does not require access to both sides of the sample
- Can be engineered to cope with coatings, linings, etc.
- Good accuracy (0.1 mm and less) can be achieved using standard timing techniques.
- Can be easily deployed, does not require laboratory conditions.
- EMAT can conduct thickness measurements through corrosion and other surface coatings on metals.
- No need to remove the coating of the metal.
