| Definition | A multibeam (swath) echosounder with video-imaging capability that uses a 120 kHz acoustic frequency. The Delta T is designed for low power consumption without a surface control box enabling it to be integrated into ROV and AUV systems. The sensor measures the depth and nature of the sea floor using a field of view of 120 x 2.5 degrees. The 2.5 degree field of view is applicable to obstacle avoidance in near-bottom applications where the narrow vertical extent of the beam reduces false obstacle detection. Operates with 120, 240 or 480 beams (3, 1.5 or 0.75 degree beam widths). Sensor can be fitted with either stainless steel or aluminium housing as standard. Resolution is 0.02% of the range. Operating depth is 1000 m. Can be combined with an azimuth drive to obtain readings from direction which may limit depth. | ||
