Broadband 85Khz-180KHz Receiving And Transmitting Acoustic Transducer for Flow Velocity
Measurement content:
1.1. Conductance and Susceptance Curves
Measure the conductance and susceptance parameters of the transducer within the 80 kHz–220 kHz frequency band.
1.2. Transmitting Response
Measure the transmitting response of the transducer within the 80 kHz–220 kHz frequency band.
1.3. Receiving Sensitivity
Measure the receiving sensitivity of the transducer within the 80 kHz–220 kHz frequency band.
1.4. Directivity
Measure the directivity at 125 kHz: horizontal omnidirectionality and a vertical beamwidth of no less than 60°.
1.5. Hydrostatic Pressure Test
The transducer's hydrostatic pressure resistance shall be no less than 1 MPa.

Horizontal Directivity
Hydrostatic pressure test:
After undergoing hydrostatic pressure testing—comprising cycles of 1 MPa for 1 hour and 0 MPa for 0.5 hour—the insulation resistance between the positive and negative terminals of the transducer exceeded 200 MΩ.
Measurement Results
Testing confirmed that the transducer meets the technical specifications.
