Indicators for Azimuth Thruster Systems
Azimuth indicators are typically used for indication of the azimuth pod in thruster propulsion
systems. As a marked standard, these indicators are featuring a rotation disc with a pod
symbol acting as a pointer. However DEIF can also offer a traditional pointer if requested by
users.
The indicators are normally used together with propeller RPM and/or propeller Pitch indicators,
forming a complete indicating system.
Approvals
As all DEIF illuminated indicators, the azimuth indicators have been MED approved. The
azimuth types are included in the rudder indication certificate, because they do not have their
own group in the directive.
Product range
Alternative mounting types are
available, both front mounted
types for console applications or
BW types for deckhead mounting.
Watertight options (IP66) available
for all types.
XL72 XL96 XL144
Design examples
Both the scales and the discs are customisable.
This means that the indicator can be tailormade
for the applicator:
Special versions with white base and black
figures and lines are also possible. These are
intended for use in engine control room switchboards
below deck, where illumination and
other MED requirements are not required.

Transducer types
The input signal to the indicators is generated from an angular transmitter,
typically a potentiometer or an encoder with some kind of
mechanical interface to the pod. DEIF is able to handle the following
types as standard:
1. Single analog signal
Signal generated from a single potentiometer and transmitted as
4-20mA, 0-10V, etc. from an amplifier/driver to the indicator. This
solution has some inherent problems and is typically used in low-cost
solutions.
2. Double analog signal (SIN/COS)
Signal generated from a double SIN/COS potentiometer and transmitted
as 4-20mA, 0-10V, etc. from an amplifier/driver to the indicator.
This solution is almost standard as the analog signal type.
3. CANopen signal
Signal generated from an optical encoder and transmitted as a CANopen
signal. This signal type is gaining use as more and more solutions
are using CAN.

Be sure that the scale designs and the indicators electrical mids are fitted to the actual indicator position (aft or fwd bridge).
The standard range of scale and disc combinations includes versions for both fwd and aft bridge layouts. Note that both the visual design and the position of the
disc have been changed on the Azimuth indicator on the aft bridge.
See the Disc Selector Guide on DEIF’s homepage for more standard design suggestions. Alternatively, let us design a version that fits your special requirements.
