A dual-crystal straight transducer is a transducer with independent transmitting and receiving crystals, creating a focused image within the workpiece.

● Performance Characteristics:
1. No initial wave blind zone.
2. Low scattering, improving the signal-to-noise ratio in the detection of high-attenuation, high-scattering materials.
3. Good coupling effect on curved or rough surfaces.
4. Two types of probes to meet most detection requirements:
"PL" general-purpose series, "C" piezoelectric composite ceramic series

● Applications:
1. Corrosion monitoring
2. Remaining wall thickness measurement
3. Coating measurement
4. Near-surface defect detection
5. Detection of cracks, porosity, inclusions, and porosity in castings and forgings
6. High-attenuation material detection
