TYPE: BRW-1-PC-PY
BRIDGE WING INDICATOR
RANGE: 200-0-200 RPM
INPUT: 2,5-0-2,5 MA
LOAD: <150 OHM
ORDER NO.: 236395.20
The DEIF BRW-1-PC-PY is a bridge wing shaft speed indicator designed to display propulsion RPM data at the bridge wing station. Operating across a range of 200-0-200 RPM with a 2.5-0-2.5 mA analogue input signal and a load impedance of less than 150 Ohm, this instrument forms a critical part of a vessel’s Marine Control System. It enables officers on the bridge wing to monitor engine and shaft speed in real time, supporting safe manoeuvring during berthing, port approach, and close-quarters navigation where direct visual contact with the surroundings is essential.
Key Features
✓ Bidirectional RPM display covering a 200-0-200 RPM range, allowing clear indication of both ahead and astern propulsion states from the bridge wing position.
✓ Analogue current input of 2.5-0-2.5 mA with a load of less than 150 Ohm, as specified in the original product data; all other electrical ratings are subject to confirmation from the unit nameplate or DEIF documentation.
✓ Designed for integration within DEIF bridge control and telegraph systems, including compatible repeater and indicator networks; exact panel or controller compatibility should be confirmed against the installation drawings.
✓ Intended for bridge wing mounting — a weatherproof or protected enclosure environment depending on vessel arrangement — supporting continuous operational visibility during manoeuvring situations relevant to bridge watch requirements.
✓ Direct replacement or retrofit indicator for existing DEIF bridge wing installations; order number 236395.20 should be quoted when cross-referencing against original system documentation to confirm fit and function.
Marine Applications
✓ Merchant vessels including bulk carriers, tankers, and container ships where bridge wing RPM indication is required during port approach and departure.
✓ Ro-Ro and passenger ferries where officers frequently operate from the bridge wing during tight manoeuvring in confined waterways or ferry terminals.
✓ Offshore support vessels and platform supply vessels requiring accurate shaft speed monitoring at all conning positions.
✓ Naval and government vessels fitted with DEIF control and telegraph systems where redundant RPM indication at wing stations is part of the bridge layout specification.
✓ Any vessel where DEIF bridge control infrastructure is installed and a replacement or additional wing indicator is required to maintain full system functionality.
Why Marine Engineers Choose
DEIF bridge wing indicators are valued for their direct compatibility with existing DEIF telegraph and control architectures, their straightforward analogue signal interface, and their reliable readability under bridge wing conditions. Sourcing a genuine DEIF type-matched indicator minimises integration risk and reduces commissioning time compared to non-OEM alternatives.
Ideal For
Merchant fleet operators, ship managers, and vessel owners operating tonnage fitted with DEIF bridge control systems; also suitable for shipyards, system integrators, and marine electrical contractors undertaking bridge refits, control system upgrades, or like-for-like replacements across any vessel class or flag state.
Technical Support & Compliance
Technical assistance is available to support installation verification, signal loop commissioning, and integration with existing DEIF bridge control or telegraph systems, subject to confirmation of the specific installation context. Guidance on wiring, input signal calibration, and panel compatibility can be provided remotely or through onboard support depending on requirements. To confirm suitability and compatibility, buyers are encouraged to share the unit nameplate photograph, order number, relevant system drawings or wiring diagrams, the vessel name and IMO number, and details of the existing DEIF control system model or version. All compatibility and fitment statements are subject to confirmation against the actual installation.
