Deep penetration probes are specially designed to generate more powerful ultrasound signals. Leverage the improved penetration provided by these probes’ wider elevations (element heights) to perform nondestructive testing of thicker carbon steel as well as noisy and granular materials.
Advantages
- Extra-wide elevation generating increased ultrasonic energy
- Available in different frequencies, depending on your need for higher definition or deeper penetration
- Available with higher element counts (A33) for advanced techniques such as TFM, PCI, or compound scans.
Typical applications
A3, A4, A5 and A33 probes
Deep penetration inspection applications
- Thick plates and welds
- Forging
- Noisy or granular material
