Overview
Advantages of Phased Array Probes
- Ability to transmit and receive longitudinal waves in granular materials.
- Increased penetration in stainless steel, including austenitic, corrosion-resistant alloys, and dissimilar welds.
- Excellent signal-to-noise ratio.
- Higher frequencies and smaller elements provide benefits for applications requiring detection of very small indications.
