The DEIF Norcontrol DLQ 144-PC-NB is a panel-mounted RPM meter designed for precise shaft or engine speed indication across a range of 0 to 150 RPM in both ahead and astern directions. As part of the Norcontrol marine control system range, this instrument provides critical real-time rotational speed feedback to bridge and engine control room operators. Accurate RPM monitoring is fundamental to safe manoeuvring, engine load management, and propulsion system oversight, making this meter an operationally essential component aboard a wide range of commercial and industrial vessels.
Key Features
✓ Bidirectional RPM indication from 0 to 150 RPM covering both ahead and astern propulsion states, supporting full manoeuvring awareness.
✓ Analogue voltage input rated at 10-0-10V with a minimum load of greater than 94 Ω and an adjustment tolerance of ± 10%, as specified on the unit nameplate.
✓ Designed for integration within DEIF Norcontrol marine control and monitoring panels, compatible with systems utilising the DLQ 144-PC-NB instrument format — subject to confirmation against specific panel configuration.
✓ Panel-mount format suitable for installation in enclosed bridge consoles, engine control room mimic panels, or cargo control stations where environmental conditions are controlled.
✓ Direct replacement for failed or degraded RPM meters within existing Norcontrol installations, supporting continuity of system function without panel modification — compatibility should be verified against original drawings and nameplate data.
Marine Applications
✓ Main propulsion RPM monitoring on merchant vessels including bulk carriers, tankers, and general cargo ships equipped with Norcontrol bridge or engine control systems.
✓ Engine control room instrumentation panels where real-time shaft speed data is required for watch-keeping and manoeuvring operations.
✓ Offshore support vessels and platform supply vessels where precise propulsion feedback is critical during dynamic positioning and close-quarters manoeuvring.
✓ Ferry and RoRo vessel control consoles requiring continuous bidirectional RPM indication during frequent port approach and departure cycles.
✓ Retrofit and panel refurbishment projects on vessels with legacy Norcontrol control systems seeking like-for-like instrument replacement.
Why Marine Engineers Choose
The DEIF Norcontrol DLQ 144-PC-NB RPM meter is a trusted panel instrument with clearly defined electrical parameters, offering straightforward integration into existing Norcontrol control architectures and reliable indication performance for propulsion monitoring duties.
Ideal For
Merchant vessels, offshore support vessels, ferries, RoRo carriers, bulk carriers, and tankers operating Norcontrol or compatible DEIF marine control and monitoring systems.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, onboard diagnostics, installation, and commissioning of this RPM meter within existing control system configurations. Repair, retrofit, and system integration support can be arranged depending on scope and vessel schedule — subject to confirmation. To confirm compatibility and suitability, buyers are advised to share nameplate photographs, the original part number, relevant panel drawings or system schematics, the control system model and software version where applicable, and vessel name or IMO number. Providing this information at enquiry stage allows accurate cross-referencing and avoids fitment errors.
