The Deif Norcontrol 150-0-150 RPM Meter is a bidirectional analogue speed indicator designed for use within marine control and monitoring systems. Spanning a range from 150 RPM astern through zero to 150 RPM ahead, it provides the bridge or engine control room operator with a clear, continuous readout of shaft or engine rotational speed in both ahead and astern directions. The 24VAC/DC illumination enables reliable visibility under all ambient lighting conditions. As a component of a Marine Control System, this instrument plays a critical role in propulsion management, manoeuvring operations, and engine performance monitoring onboard commercial and industrial vessels.
Key Features
✓ Bidirectional RPM indication across a 150-0-150 RPM scale, covering full ahead and full astern operational ranges for precise propulsion monitoring.
✓ Panel illumination rated at 24VAC/DC, ensuring clear dial visibility in dimly lit control rooms, bridge consoles, and engine control panels.
✓ Designed for integration with Deif and Norcontrol marine control and automation systems; compatibility with specific panels or controllers is subject to confirmation based on system model and configuration.
✓ Suitable for flush panel mounting in bridge consoles, engine control rooms, or local control stations; exact cutout dimensions and installation requirements should be verified against vessel drawings.
✓ Replacement of this instrument should reference the original part markings and system documentation to ensure correct signal input compatibility and scale calibration.
Marine Applications
✓ Bridge and engine control room RPM indication on merchant vessels, ferries, and offshore support vessels during manoeuvring and passage.
✓ Propulsion shaft speed monitoring on vessels equipped with Norcontrol or Deif integrated automation and control systems.
✓ Engine telegraph and speed reference display within integrated bridge systems and engine management consoles.
✓ Controllable pitch propeller (CPP) and fixed pitch propeller (FPP) installations where bidirectional shaft speed readout is operationally required.
✓ Retrofit or spares replacement in existing Norcontrol-equipped vessels requiring like-for-like instrument substitution on legacy control panels.
Why Marine Engineers Choose
The Deif Norcontrol RPM meter is a trusted panel instrument recognised for its clear bidirectional scale and compatibility with established marine automation architectures. Its straightforward illuminated analogue display supports fast, reliable speed reading during critical manoeuvring phases without dependence on digital subsystems.
Ideal For
Merchant cargo vessels, tankers, ferries, passenger ships, offshore support vessels, and any commercial marine application running Deif or Norcontrol bridge and engine control systems requiring bidirectional RPM indication.
Technical Support & Compliance
Technical assistance is available to support troubleshooting, onboard diagnostics, installation verification, and commissioning of this RPM meter within existing control panel arrangements. Retrofit feasibility, signal input compatibility, and integration with current or legacy Norcontrol systems can be assessed — subject to confirmation. To confirm suitability, buyers are advised to share nameplate photographs, the original part number or reference codes, panel arrangement drawings, system model and software version where applicable, and vessel name or IMO number together with the intended scope of supply or installation.
