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 uses a 260 kHz acoustic frequency and 120 x 3 degrees field of view to measure the depth and nature of the sea floor. Operates with 120, 240 or 480 beams (3, 1.5 or 0.75 degree beam widths). Sensor is fitted with titanium housing as standard. Resolution is 0.02% of the range. Can be combined with an azimuth drive to obtain readings from direction which may limit depth."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1345" ; skos:note "accepted"@en ; skos:prefLabel "Imagenex Delta T 837B 4000 m (profiling) multibeam echosounder"@en ; skos:related , . skos:related . skos:related . skos:narrower . skos:narrower . skos:narrower . skos:related .
