Description
DEIF
NOR CONTROL
150-0-150 RPM METER
The DEIF NOR Control 150-0-150 RPM Meter is an analogue indicating instrument designed to display engine or shaft rotational speed across a bidirectional range, covering ahead and astern operation. Forming part of a ship’s Marine Control System, this type of RPM meter is typically installed at the engine control console, bridge panel, or local machinery control station, giving operators a direct, continuous readout of propulsion shaft speed. Accurate RPM indication is operationally critical for engine order execution, manoeuvring control, and propulsion load management.
Key Features
✓ Bidirectional 150-0-150 RPM scale covering both ahead and astern shaft rotation, suitable for controllable and fixed pitch propeller installations.
✓ Analogue panel meter format typical of DEIF NOR Control instrumentation; exact voltage input, signal type, and dimensional specification subject to confirmation from nameplate or documentation.
✓ Designed for integration with DEIF NOR Control engine telegraph and propulsion control systems; compatibility with specific panels or controllers should be confirmed against system drawings.
✓ Intended for installation in enclosed control stations such as ECR consoles or bridge instrumentation panels; mounting configuration and cutout dimensions subject to confirmation.
✓ Replacement of this meter supports continuity of propulsion monitoring capability; sourcing an OEM DEIF unit helps maintain system consistency and reduces recalibration requirements.
Marine Applications
✓ Engine control rooms on motor vessels requiring continuous shaft RPM display during manoeuvring and sea passage.
✓ Bridge propulsion control consoles on ferries, RoRo vessels, and offshore support vessels where ahead and astern indication is critical.
✓ Local machinery control panels on bulk carriers, tankers, and general cargo vessels fitted with DEIF NOR Control systems.
✓ Retrofit and replacement applications where an original DEIF NOR Control RPM meter requires like-for-like substitution.
✓ Vessel upgrade projects integrating or refurbishing existing NOR Control propulsion instrumentation panels.
Why Marine Engineers Choose
DEIF NOR Control instrumentation has a long-standing presence in marine propulsion and engine control applications. Engineers specify original DEIF panel meters to maintain measurement consistency, preserve system aesthetics, and avoid reconfiguration of existing signal wiring and control panel layouts.
Ideal For
Motor vessels, ferries, offshore support vessels, bulk carriers, tankers, RoRo vessels, and general cargo ships fitted with DEIF NOR Control propulsion monitoring and engine control systems.
Technical Support & Compliance
Technical assistance is available to support troubleshooting, identification, and integration of this RPM meter into existing control systems. Support can extend to installation guidance, panel retrofit advice, and compatibility verification, subject to confirmation. To confirm suitability, buyers are encouraged to share nameplate photographs, any available part numbers or drawing references, the specific NOR Control panel or system model and version, and vessel name or IMO number where applicable. Providing this information at enquiry stage allows accurate cross-referencing and ensures the correct unit is supplied for the intended application.
