| KW980 Dual Axis Speed Log |
| |
The KW980 Log provides
dual axis speed over ground data. This information
is invaluable when conducting docking and anchoring
manoeuvres.
The KW980 uses a standard 12-channel GPS equipment to produce original outputs,
which are then displayed in real-time

The water speed transducers
use the correlation principle which
is influenced less by turbulence and
fouling than electromagnetic logs.
For refits AMI, or a shipyard, can
produce a housing for the new transducer
to match the old transducer, allowing
an existing gate valve or tank to be
reused. The transducer is supplied
with a simple housing for new fittings.
Gate valves are made by Lloyds/DNV/etc
approved manufacturer.
The ground speed measurement is
based on the proven SMIDS "doppler" docking
system.
The KW992 master unit processes
the raw data and has selectable graphic display screens.
Additional KW992 repeaters may be connected. Their displays show
1. All data and system
health.
2. Large figures with arrows for water speed. Distance run, ahead.
3. Large figures with arrows for ground speed. Distance run, ahead.
4. Settings screens control operation and data output formats.
Additional displays may be connected using the internal power supply. The
NMEA outputs may feed ECDIS, radar, VDR, a conning display or small display
instruments available from other manufacturers. Miniature screened cable
is used and long runs are no problem at all.
