INPUT: 10-0-10V
The Deif Norcontrol DLQ144-PC-NB is a panel-mounted analog RPM meter designed to provide clear, continuous indication of engine shaft speed across both ahead and astern directions. With a bidirectional range of 100-0-100 RPM, this instrument is purpose-built for marine engine control applications where precise rotational speed monitoring is critical to safe manoeuvring and machinery management. As a key component within the Marine Control System, it integrates into bridge and engine room control consoles to give operators immediate visual feedback on propulsion status.
Key Features
✓ Bidirectional analog RPM indication with a 100-0-100 ahead/astern range, suitable for direct-reading propulsion monitoring on marine vessels.
✓ Accepts a 10-0-10V analog input signal, with an adjustment tolerance of ±10%, allowing calibration to match specific machinery signal outputs — subject to confirmation for exact system configurations.
✓ Designed for integration with Deif Norcontrol marine control and automation panels, making it compatible with existing Norcontrol bridge and machinery automation systems typical of its generation.
✓ Panel-mount format suitable for installation in enclosed control consoles, bridge wing stations, or engine control rooms; exact enclosure rating and mounting dimensions should be confirmed against installation drawings.
✓ As a direct OEM-type replacement component, sourcing the correct meter supports system integrity and minimises recalibration effort during maintenance or instrument changeout.
Marine Applications
✓ Main propulsion control consoles on merchant vessels requiring continuous ahead/astern RPM indication during manoeuvring operations.
✓ Engine control rooms on cargo ships, bulk carriers, and tankers fitted with Deif Norcontrol automation and bridge control systems.
✓ Integrated bridge systems where shaft speed data must be displayed locally alongside telegraph and pitch indicators.
✓ Offshore support vessels and platform supply vessels where precise propulsion feedback is essential for dynamic positioning and close-quarters manoeuvring.
✓ Retrofit and refurbishment projects on vessels with legacy Norcontrol control systems requiring like-for-like instrument replacement.
Why Marine Engineers Choose
The Deif Norcontrol DLQ144-PC-NB is a recognised instrument within established Norcontrol control architectures, offering a direct replacement path that preserves signal compatibility and display consistency without requiring panel modifications or signal conditioning — a practical advantage during time-sensitive maintenance windows.
Ideal For
Merchant cargo vessels, bulk carriers, tankers, container ships, offshore support vessels, and any vessel class operating with Deif Norcontrol marine automation and propulsion control systems requiring analog RPM indication.
Technical Support & Compliance
Technical assistance is available to support installation, commissioning, calibration, and troubleshooting of this RPM meter within Norcontrol control system environments. Repair and retrofit guidance can be provided depending on the scope of work required, subject to confirmation. To verify compatibility and ensure the correct part is supplied for your application, buyers are encouraged to share nameplate photographs, the original order number, control system model and software version where applicable, installation or wiring drawings, and vessel name or IMO number. All compatibility and fitment claims are subject to confirmation based on documentation provided.
