Electro-Magnetic Acoustic Transducer (EMAT)

Electro-Magnetic Acoustic Transducer (EMAT) technology is first in a series of inspection methods and tools that make us a leader and pioneers in the field of corrosion detection. ACTT’s EMAT inspection technique can be used on any conductive material and exotic alloys such as Hastelloy furnace tubes and is ideal for many types of corrosion detection applications.

Speed and accuracy of EMAT is superior to other automated scanning systems and EMAT can handle rough, coated surfaces.

Why Use EMATs?

• Can be used In-Service or during outages
• Can be used in High Temperature Applications up to 1000F
• EMATs can tolerate adverse conditions such as rough, coated, or wet surfaces.
• High speed screening
• Capable of covering large areas (approx. 1 ft per second)
• EMATs can inspect areas not normally accessible such as buried or hidden regions
• Lightweight and portable
• No couplant needed
• Repeatable Data
• Up to 100% Coverage
