Transducer description
The EM 2040 MKII system uses separate transducers for transmitting and receiving
sound pulses.
The EM 2040 MKII system may be delivered in
different versions with different transmission beam
width.
• EM 2040-04 MKII (0.4 degrees at 400 kHz)
• EM 2040-07 MKII (0.7 degrees at 400 kHz)
The transducers are made from composite ceramics
which enables a wide bandwidth. The material in the
transducer housing is Titanium.
The EM 2040 MKII system is fully prepared for upgrading to cater for more demanding
applications. Adding a second receive transducer increases the angular coverage.
The cables are connected to the transducers with underwater connectors. The standard
length of the transducer cables is 15, 30 or 50 metres.
Caution
The transducers shall under no circumstances be opened or attempted repaired in field.
Malfunctions reported by the Built-In Self Tests shall be reported to Kongsberg Maritime
support for troubleshooting and/or replacement instructions. Any attempts to open
the transducer may void the guarantee.
