The DEIF Norcontrol DLQ144-PC-NB is a panel-mounted RPM meter and indicator designed for use within marine control systems aboard commercial and offshore vessels. Operating across a bidirectional range of astern 200-0-200 ahead, the instrument provides real-time rotational speed indication for main propulsion engines, shaft systems, or auxiliary drives. With a ±10% adjustment range and a 10V analogue input signal, it integrates into automation and monitoring panels where precise, continuous RPM readout is operationally critical. As part of the Marine Control System category, this instrument supports safe manoeuvring, engine load management, and bridge or engine room supervisory functions.
Key Features
✓ Bidirectional RPM indication with a range of astern 200-0-200 ahead, with ±10% field adjustment capability for calibration to specific machinery configurations.
✓ Analogue voltage input of 10…0…10V with a load requirement greater than 104Ω, as specified in the original product data — no additional electrical ratings are assumed.
✓ Designed for integration with Norcontrol and DEIF marine automation and monitoring panels; compatibility with specific systems or controllers subject to confirmation based on vessel configuration.
✓ Panel-mount format (DLQ144 series, 144mm square front) suited to engine control room consoles, bridge manoeuvring panels, or local control stations in protected onboard environments.
✓ Replacement and retrofit applications should be verified against the original nameplate reference 1113150035A and the vessel’s existing wiring and signal conditioning setup prior to installation.
Marine Applications
✓ Main propulsion engine RPM monitoring on merchant vessels, tankers, bulk carriers, and general cargo ships operating fixed or controllable-pitch propeller systems.
✓ Bridge manoeuvring and engine control room panels aboard RoRo vessels, ferries, and passenger ships where continuous shaft speed indication is required during port approach and departure.
✓ Offshore support vessels and platform supply vessels utilising DEIF or Norcontrol integrated automation systems for dynamic positioning or conventional propulsion monitoring.
✓ Auxiliary machinery monitoring installations where bidirectional speed indication is required for thrusters, bow thrusters, or stern tube shaft assemblies.
✓ Upgrade and panel refurbishment projects on ageing vessels where original Norcontrol instrumentation requires like-for-like replacement to maintain system continuity.
Why Marine Engineers Choose
The DLQ144-PC-NB is a purpose-built marine RPM indicator from an established automation brand, offering a straightforward analogue interface, field-adjustable calibration, and a form factor suited to standard marine control panels — making it a reliable choice for both OEM replacement and panel retrofit scenarios.
Ideal For
Merchant vessels, tankers, bulk carriers, offshore support vessels, ferries, RoRo ships, and any commercial or industrial marine application operating Norcontrol or DEIF engine monitoring and control systems requiring bidirectional RPM indication.
Technical Support & Compliance
Technical assistance is available to support identification, compatibility checking, installation guidance, testing, and commissioning of this RPM meter within existing marine automation systems. Retrofit and integration support can be provided subject to confirmation of the vessel’s control system architecture and panel configuration. To confirm suitability and avoid misapplication, buyers are encouraged to share nameplate photographs, the full part number, any associated system drawings or wiring diagrams, the control panel or automation system model and software version, and vessel name or IMO number where relevant. All compatibility assessments are subject to confirmation based on the information provided.
