M194 High-Frequency Ultrasonic Transducer Applications • River, harbor, and estuary survey Features • Broadband with low Q of 2 • Minimal sidelobes for concentrated energy on target providing excellent definition • Internal transformer provides impedance match to echosounder and allows use of longer cable • 500 W RMS, power rating is at 2% duty cycle • Do not strike or use solvents (especially acetone) on the transducer face. Use water-base anti-fouling paint only. Do not cut transducer cable. • Seamless, SEALCAST™, urethane housing resists cuts and abrasion and has excellent, impact resistance Options • Impedance to customer’s specifications using matching transformer Dimensions Technical Data—200 kHz-BClq TVR in dB re 1μPa/Volt at 1 m RVR in dB re 1 Volt/μPa SPECIFICATIONS Weight: 1.5 kg Acoustic Window: Urethane Cable Type: C-33—Shielded twisted pair (2-20 AWG) with braided shield, black neoprene jacket, 6 mm diameter Frequencies Configuration Beamwidth (@-3 dB) RMS Power (W) FOM (dB) Q Series Imped- ance (R-jX) 200 kHz-BClq Broadband 8° 500 W -16 2 60-j0(t) 180 175 170 165 160 100 150 200 250 300 Frequency (kHz) dB (1) TVR -185 -190 -195 -200 -205 100 150 200 250 300 Frequency (kHz) dB (2) RVR 0 -10 -20 -30 -40 100 150 200 250 300 Frequency (kHz) dB (3) FOM -10 dB -20 dB -30 dB -40 dB 60° 90° 60° 90° 30° 30° 0° Directivity Pattern— 200 kHz-BClq Echogram Vertical: 1E+03 V/DIV Horizontal: 500E-6 SEC/DIV ø 95 mm 72 mm 12 mm 48 mm ø 75 mm ø 110 mm ø 11 mm 6 mm typical ø 6 mm; 6 places equally spaced
