The DEIF DLQ144-PC-NB is a panel-mount RPM meter designed for accurate rotational speed indication within marine engine control and monitoring systems. Covering a bidirectional range of 100-0-100 RPM, this instrument is suited to applications where both ahead and astern shaft or engine speed must be clearly displayed. As a key component within a vessel’s marine control system, it provides operators and engineers with real-time speed feedback critical to safe manoeuvring, engine management, and machinery protection.
Key Features
✓ Bidirectional RPM display with a 100-0-100 RPM range, allowing both ahead and astern speed indication from a single instrument.
✓ Signal input rated at +10V with an input impedance of greater than 10K OHM, as specified in the original product data; all other electrical parameters are subject to confirmation against system drawings.
✓ Panel-mount 144mm format (DLQ144 series) suitable for integration into engine control consoles, machinery control rooms, and bridge instrument panels — mounting dimensions and cutout requirements should be confirmed prior to installation.
✓ Designed for compatibility with DEIF control and monitoring architectures; suitability for specific panels, controllers, or automation platforms should be verified against the original system configuration.
✓ As a direct OEM replacement carrying the original DEIF order reference, this meter supports like-for-like swap-out, minimising commissioning time and configuration changes during planned maintenance or unscheduled repair.
Marine Applications
✓ Main engine and propulsion shaft speed monitoring on merchant vessels, ferries, and offshore support vessels requiring clear ahead/astern RPM indication.
✓ Engine control room and bridge console instrumentation where centralised speed readout is required as part of an integrated machinery monitoring system.
✓ Thruster and CPP (controllable pitch propeller) control panels where rotational direction and speed must be simultaneously displayed.
✓ Auxiliary engine and generator set monitoring applications where panel-mount analogue or digital speed indication supports operational oversight.
✓ Retrofit and upgrade projects modernising ageing control panels with direct-replacement DEIF instrumentation to maintain system consistency and spare part standardisation.
Why Marine Engineers Choose
The DEIF DLQ144-PC-NB is a recognised OEM instrument from DEIF, a manufacturer with a strong reputation in marine power management and control. Its defined signal interface, bidirectional range, and panel-mount format make it a practical, dependable choice for vessels running DEIF-based control infrastructure, supporting accurate speed monitoring and reducing the complexity of panel replacements.
Ideal For
Merchant cargo vessels, tankers, bulk carriers, RoPax ferries, offshore support vessels, tugs, dredgers, and any commercial or industrial marine application utilising DEIF engine control or machinery monitoring systems requiring panel-mount RPM indication.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, installation guidance, onboard commissioning, and integration of this RPM meter into existing control system configurations. Retrofit and upgrade compatibility is subject to confirmation based on the specific panel version, signal source, and system layout. To confirm suitability before ordering, buyers are encouraged to share nameplate photographs, the original part number and order reference, system model and software version where applicable, relevant wiring or panel drawings, and vessel name or IMO number. All compatibility and fitment claims are subject to confirmation against verified technical documentation.
