Focused Probes for Piping

A focused probe can be used in immersion testing for piping. The curved probe will counteract the effect of the curvature on beam spread, therefore, enhancing the sensitivity.

1. Without the acoustic lens, most of the ultrasound wave remains in the pipe and very little comes back to the probe. Sensitivity is low
2. With the acoustic lens, the ultrasound wave is concentrated on the top of the pipe ensuring that most of it comes back to the probe. Sensitivity is high

In a curved probe, the element of the probe can also be curved allowing for the use of flat wedges.
