The EA440 also supports portable and hull mounted sidescan and sub-bottom applications for shallow waters.\n\nThe standard 4-channel Wide Band Transceiver (WBT) of the EA440 transmits and receives simultaneously on 4 channels from 10 kHz to 500 kHz, and the channels can be configured for different applications or redundancy. The EA440 covers hydrographic depth observations from 30 kHz to 500 kHz, sidescan sonar from 100 kHz to 500 kHz and sub-bottom profiling from 10 kHz to 30 kHz, for applications from 0.2 m to 3000 m water depth. CW and FM pulse forms are supported, with a ping rate of max 40 per second and a precision of 0.3 cm at 500 kHz (CW 32 to 512 µs) to 9.8 cm at 10 kHz (CW 1 to 16 ms).\n\nThe WBT communicates over Ethernet with a Windows 10 computer running the EA440 software, and several WBTs with different configurations can be used. Transducers are enabled through license management, with license codes provided by Kongsberg Maritime Support, and both Kongsberg and third-party transducers can be interfaced. The EA440 accepts GPS, gyro, motion, speed, temperature and sound speed sensor inputs, outputs NMEA (DBS, DBP, DPT), Simrad, Atlas and Hymas, and exports raw data, XTF, SEG-Y, XYZ, echogram, EA400, marker and parameters. The EA440 map view shows the vessel, vessel tracks and sidescan coverage on user-supplied WMS or GeoTIFF maps, and all raw sample data, including external sensor data, is stored internally for replay.\n\nThe EA440 WBT measures 438 × 213 × 84 mm (W × D × H), weighs 5 kg, has an IP42 rating and requires 12 to 15 VDC, 5 A, with a power supply for 220\u002F110 VAC operation provided with the delivery. The EA440 operates at 0 to 50 °C, can be stored at −40 to 70 °C and handles relative humidity of 5 to 95 %, non-condensing. The datasheet also covers the EA440SP splash proof version, with an 11 kg unit, an IP56 suitcase when closed and an IP65 rugged PC.",[235,236,237,238,239,240],"4-channel wide band transceiver, 10–500 kHz","Applications from 0.2 m to 3000 m water depth","Ping rate max 40 per second","Precision 0.3 cm at 500 kHz (CW 32–512 µs)","Sidescan 100–500 kHz, sub-bottom 10–30 kHz","WBT 5 kg, IP42, 12 to 15 VDC","Kongsberg",{"_type":243,"asset":244},"image",{"_ref":245,"_type":229},"image-5bcb546cb0c504c4b254e59f18af8ad45bab3fe0-759x584-png","Rent a Kongsberg EA 440 single beam echosounder: 4-channel wide band transceiver from 10 to 500 kHz, CW and FM pulses, for 0.2 m to 3000 m water depths.","EA 440 Single Beam Echosounder","Kongsberg EA 440 hydrographic wide band single beam echosounder with a 4-channel transceiver covering 10–500 kHz, for applications from 0.2 m to 3000 m water depth at up to 40 pings per second.",{"_type":250,"current":251},"slug","kongsberg-ea-440-single-beam-echosounder","Hydrographic Wide Band Single Beam Echosounder",[254,259,263,267,271,275,279,283,287,291,295,299,303,307,311,315,319,323,327,331,335,339,343,347,351,355,358,362,366,370,374,378,382,386,390,394,398,402,406,410,414],{"_key":255,"_type":256,"label":257,"value":258},"a58015bfd2ed","specRow","Transceiver","4-channel Wide Band Transceiver (WBT), 10 kHz to 500 kHz",{"_key":260,"_type":256,"label":261,"value":262},"30aedd753eef","Application depth","0.2 m to 3000 m water depths",{"_key":264,"_type":256,"label":265,"value":266},"da7394873164","Hydrographic depth observations","30 kHz to 500 kHz",{"_key":268,"_type":256,"label":269,"value":270},"5901ea35b4dd","Sidescan sonar application","100 kHz to 500 kHz",{"_key":272,"_type":256,"label":273,"value":274},"3e27ac96c99d","Sub-bottom profiler application","10 kHz to 30 kHz",{"_key":276,"_type":256,"label":277,"value":278},"9c7c563c3ac3","High power output","30 kHz to 50 kHz (available)",{"_key":280,"_type":256,"label":281,"value":282},"56e49854314a","Pulse forms","CW and FM",{"_key":284,"_type":256,"label":285,"value":286},"127c401153f2","Pulse length and precision, 500 kHz","CW 32 to 512 µs, 0.3 cm",{"_key":288,"_type":256,"label":289,"value":290},"c1d04fa3c05b","Pulse length and precision, 200 kHz","CW 64 to 1024 µs, 0.6 cm",{"_key":292,"_type":256,"label":293,"value":294},"db06e56b947b","Pulse length and precision, 38 kHz","CW 256 to 4096 µs, 2.4 cm",{"_key":296,"_type":256,"label":297,"value":298},"0554df8d0442","Pulse length and precision, 15 kHz","CW 512 to 8192 µs, 4.9 cm",{"_key":300,"_type":256,"label":301,"value":302},"feb6307e4ca0","Pulse length and precision, 10 kHz","CW 1 to 16 ms, 9.8 cm",{"_key":304,"_type":256,"label":305,"value":306},"5941402aabfa","Ping rate","Max 40 per second",{"_key":308,"_type":256,"label":309,"value":310},"6492679cf310","Display range","1 to 12.500 m (as written in datasheet)",{"_key":312,"_type":256,"label":313,"value":314},"b8c775cfd145","Transducer range","30 to 500 kHz",{"_key":316,"_type":256,"label":317,"value":318},"cd5353e0c864","Sub-bottom range","10 to 30 kHz",{"_key":320,"_type":256,"label":321,"value":322},"2bb1620a60a3","Sound speed","Manual (1400 to 1700 m\u002Fs), calculated from temperature and salinity, or from sound velocity probe",{"_key":324,"_type":256,"label":325,"value":326},"e7ce70beb758","Transceiver interface","Ethernet communication",{"_key":328,"_type":256,"label":329,"value":330},"1fca4fa28ac8","Network","Ethernet to ship's network",{"_key":332,"_type":256,"label":333,"value":334},"1b8bb42fcc48","Sensor inputs","GPS, gyro, motion, speed, temperature and sound speed",{"_key":336,"_type":256,"label":337,"value":338},"d71bb1cf34d8","Remote control","Remote stop\u002Fstart logging on serial line or network",{"_key":340,"_type":256,"label":341,"value":342},"7b081b68c4e8","Main control","Mouse, trackball or touch screen",{"_key":344,"_type":256,"label":345,"value":346},"ed1cce68c0ce","Menu languages","English, Norwegian and a variety of other languages",{"_key":348,"_type":256,"label":349,"value":350},"45d1e1e52ae2","Supported output","NMEA (DBS, DBP, DPT);
