Dimension of piezo hemisphere:
P-5H material
80 mm OD x 5.5mm wall thickness hemispheres
Fs(Hz): 24632
Fp(Hz):29510
Capacity(pf): 46000
Application: underwater acoustic
Application of Hydroacoustic Transducers:
Collecting Multibeam Sonar DataHydroacoustics can be used to detect the depth of a water body (bathymetry), as well as the presence or absence, abundance, distribution, size, and behavior of underwater plantsand animals. Hydroacoustic sensing involves "passive acoustics" (listening for sounds) or active acoustics making a sound and listening for the echo, hence the common name for the device, echo sounder or echosounder.

PZT Material:
- PZT4 Piezoelectric ceramics have a double behavior of receiving and transmitting, with higher sensitivity and lower dielectric loss.
- PZT5 Piezoelectric ceramics have higher electro-mechanical coupling coefficient, the moderate dielectric constant and higher sensitivity.
- PZT8 Piezoelectric ceramics of high power transmission type have good piezoelectric property, high mechanical strength, high coercive field, low dielectric loss in strong fields.
