The DL1-Multi single axis Doppler speed log system is a vessel mounted system
that measures speed in one axis (longitudinal) through the water. The system
fulfils all class and type regulations based on MED B (wheelmark).
The system requires no external inputs, however adding inputs from other
navigational systems enhances the functionality and allows comprehensive
quality control of the data.
The system comprises of 3 units;
1. The control uni
t – The system requires a small control unit (CD402CU-XX)
to display and set up the required parameters. All setup parameters are also
available by connecting to the electronic units web page via a LAN cable.
2. The electronic unit
– This unit (JB70D1-XX) comprises of a processor/IO
board and a power supply. It is packaged in a compact single euro cabinet.
This units electronics enable the user to interface to both modern and older
navigation systems with all the expected connectivity. The unit has a built-in
web server, allowing the system to be fully integrated into existing navigation
systems (extra approvals may apply).
3. The sensor
– The sensor (DL1SXX-XX) contains 2 acoustic elements and a
fully programmable transceiver unit, allowing the system to adapt itself to the
conditions and requirements. In addition, the sensor contains a temperature
sensor for internal compensation and quality control.
4. The sensor is installed into a sea valve or tank welded into the hull.
