Technical specifications The following specifications are valid when all four quadrants are wired in parallel. Note that the specifications may be altered without prior notice. • Resonant frequency: 120 kHz • Circular beamwidth: 7 deg • Directivity: 28 dB • Equivalent two-way beam angle: -20,7 dB • Side lobes: Less than -23 dB • Back radiation: Less than -35 dB • Nominal impedance: 19 Ω (Each quadrant: 75 Ω) • Transmitting response: 183 dB re 1μPa per V • Receiving sensitivity, open circuit: -187 dB re 1V per μPa • Electro-acoustic efficiency: 0.6 Introduction The Simrad ES120-7CD is a 120 kHz split-beam composite transducer with a large bandwidth. This provides a fine range resolution, which is important for single fish detection and target strength measurements. The transducer has four quadrants. The ES120-7CD has been designed to withstand a large water pressure. It is therefore well suited for towed bodies.
