A.1 Technical Specification SES smart
Main Technical Parameters
Primary frequency range (PHF) approx. 100 kHz (band 90 – 110 kHz)
Primary source level > 235 dB//µPa re 1m
Secondary low frequencies (SLF) 10 kHz (centre frequency)
SLF total frequency band up to 5 – 15 kHz
SLF pulse type Ricker, CW
SLF pulse width 0.1 – 0.5 ms (user selectable)
Beam width (-3dB) about ±2.5° for all frequencies / footprint <9% of water depth
Heave / roll / pitch compensation heave; depending on external sensor data
Water depth range 0.5 – 100 m
Sediment penetration up to 20 m (depending on sediment type and noise)
Range / layer resolution approx. 1 cm / up to 8 cm
Pulse rate up to 40 pings/s (multi ping, burst ping available)
Data acquisition digital 16 bit / 70 kHz; full waveform
External sensor interfaces HRP (motion) sensor, GNSS position, depth, trigger
Seabed detection / bottom track internal (HF and SLF data) or external depth
Depth accuracy (2 cm @ 100 kHz / 4 cm @ 10 kHz) + 0.06% of water depth
Power supply 100 – 240 V AC / 50 – 60 Hz (fuse 16 A / slow)
or 10 – 30 V DC (optional)
Power consumption <100 W (max. power-on inrush current 20 A / <100 ms)
Environmental conditions Storage: -10…+60°C / <90% non-condensing rel. humidity
Operation: 0…+40°C / <70% non-condensing rel. Humidity
!
If the system is DC powered from a power supply unit (PSU) and not from battery, make
sure the PSU can handle the power-on inrush current (e.g. a 30V / 5A PSU is fine).
Hardware
Topside Unit
Dimensions (L×W×H) 30 cm × 40 cm × 20 cm
Housing ½ 19 inch / 4U
Weight about 13 kg
Transducer
Dimensions (L×W×H) 27 cm × 21 cm × 7 cm
Weight in air incl. 15m cable about 10 kg
The transducer cable is moulded non-removable to the trans-
ducer. The cable length is fixed to 15 meters.
For transducer drawing see page 175.
For operating the topside unit an external control computer (tablet or laptop PC; MS Windows
®
operating system) is required. This PC is not part of the supply, but may be ordered separately.
