| Definition | A series of multibeam (swath) echosounders with video-imaging capability. 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 system uses 120, 260 or optional 675 kHz acoustic frequencies to measure the depth and nature of the sea floor depending on the sub-model used. The field of view ranges from 120 x 2.5 degrees, 120 x 3 degrees or 120 x 20 degrees. Operating depth ranges from 300 - 6000 m using stainless steel, aluminium or titanium housing. All models operate with 120, 240 or 480 beams (3, 1.5 or 0.75 degree beam widths) and have a resolution of 0.02% of the range. Image update rate is 20 fps. The system can be combined with an azimuth drive to obtain readings from direction, which may limit operating depth to either 300 m or 2000 m. | ||
