Horizontal directivity

Vertical directivity

Hydrostatic Pressure Test:

After undergoing hydrostatic pressure tests at 1 MPa/1 hour, 1 MPa/0.25 hour, 1 MPa/1 hour, and 0 MPa/0.25 hour, the transducer's appearance remained intact and normal, and the insulation resistance between the transducer cores was greater than 200 MΩ.

Measurement Results:

All transducers met the technical specifications.
