CDIT's Composite Piezoelectric Transducer (CPT)
features the following super performances:
composite piezoeletric transducers including contact, dual element, protected,
delay line, angle beam, immersion, and special transducers with frequency
from 0.5MHz to 7.5HMz, element size from 0.25" to 1.125".
- High Sensitivity
The composite material has a relatively low acoustic impedance(Z), so it
has a better acoustic match with low acoustic impedance materials, such
as plastic wedges or delay line and water for immersion inspections.
Electrical energy can be converted to acoustic energy much efficiently.
- Broad Bandwidth with High Resolution & High Sensitivity
- CPT has high axial resolution and broadband (60% - 100%) traits.
- High Signal to Noise Ratio
CPT features high signal to noise (S/N) ratio. Since CPT has high
coupling coefficiency(Kt), converting between electrical energy and acoustic
energy is much efficient.
