85Khz-180KHz Broadband Receiving And Transmitting Acoustic Transducer for Flow Velocity
Technical Parameters:
1. 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.
