Dual Element Transducers
 Dual Element Transducers contain two separate elements within a single housing. These elements, mounted on delays, are acoustically isolated and are slightly angled towards each other to create a pseudo focusing effect in a test material. This tandem arrangement provides superior near surface resolution and improved performance on corroded back walls.
Dual Element Transducers use separate elements to transmit and receive ultrasound signals. The elements are typically cut at an angle and mounted on delay lines. This helps to improve near surface resolution and the cross-beam design also helps to create a focus which makes Dual Element Transducers more sensitive to echoes from irregular defects caused from corrosion and pitting.
Advantages:
- Improved near surface resolution
- Superior sensitivity of corroded back wall surfaces
- Improved signal to noise ratio on castings and other grainy materials
- Suitable for all commercial flaw detectors and some thickness gauges
