Product Description
200khz Echo Sounder Transducer Single Beam Transducer for Underwater Acoustic
Measurement content
Conductance, capacitance
Measure the conductivity and capacitance curves of the transducer, and provide the conductivity and susceptance data within the working frequency band.
Working frequency band
The working frequency band of the transducer is 190kHz-210kHz.
Transmitter response and efficiency
Measure the transmit response within the working frequency band of the transducer, of which the 200kHz is not less than 175dB,
The fluctuation within the working frequency band does not exceed 3dB, and the efficiency is not less than 50%.
Receiver sensitivity
The 200kHz receiver sensitivity should not be less than -185dB. 4.5. Directivity
The 200kHz opening angle is 5°~7°, and the side lobe is less than -23dB.
Hydrostatic pressure test
The hydrostatic pressure resistance of the transducer should be not less than 1Mpa.
Measurement data
