The DEIF 2FQ96-X is a panel-mounted double frequency meter designed to simultaneously display and monitor two independent frequency signals within a marine electrical power system. Operating across a voltage range of 340–506V and a frequency span of 55–65Hz, this instrument is purpose-built for applications where continuous, accurate frequency comparison is operationally critical. As part of a vessel’s Marine Control System, it provides essential visibility into generator and busbar frequency, supporting safe paralleling, synchronisation, and load management onboard.
Key Features
✓ Dual frequency display function allows simultaneous monitoring of two frequency sources, supporting generator synchronisation and busbar comparison within a single compact panel instrument.
✓ Rated for 340–506V input with a frequency measurement range of 55–65Hz, as specified in the original product data — additional technical tolerances are subject to confirmation from the original documentation.
✓ Designed for integration into marine switchboard panels and power management control systems; compatibility with specific DEIF controllers or third-party panels should be confirmed against system drawings.
✓ Panel-mount format (96mm face referenced by model designation) is suited to main switchboard, generator control panels, or engine room control consoles in a dry, protected installation environment.
✓ Replacement of this meter in an existing installation should reference the part number 1200027058A and original panel wiring diagrams to ensure correct signal input configuration and accurate reading calibration.
Marine Applications
✓ Generator control panels and main switchboards aboard cargo vessels, tankers, and offshore support vessels where dual frequency monitoring is required during parallel generator operation.
✓ Onboard power management systems where frequency comparison between incoming and running generators is essential prior to synchronisation and busbar connection.
✓ Engine room automation and control consoles on passenger ferries, RoRo vessels, and platform supply vessels operating variable generator configurations.
✓ Retrofit and upgrade projects on ageing switchboard installations where original DEIF instrumentation requires like-for-like replacement to maintain system integrity.
✓ Shore power and emergency generator changeover panels where frequency matching between shore supply and vessel generation must be visually confirmed by engineering crew.
Why Marine Engineers Choose
DEIF instrumentation is widely respected in the marine industry for its reliability in demanding shipboard electrical environments. The 2FQ96-X provides a straightforward, dedicated dual-frequency readout that supports confident decision-making during generator synchronisation — a function where precision and clarity directly affect vessel safety and power system stability.
Ideal For
Cargo ships, tankers, offshore vessels, platform supply vessels, passenger ferries, RoRo vessels, and any commercial or industrial vessel operating multi-generator power systems requiring accurate frequency monitoring and synchronisation support.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, onboard diagnostics, commissioning guidance, and retrofit or integration projects involving this DEIF frequency meter. Repair and bench-testing options may be available subject to confirmation. To verify compatibility with your specific installation, buyers are encouraged to share nameplate photographs, existing panel drawings or wiring diagrams, the system model and software version where applicable, vessel name or IMO number, and the full scope of the replacement or upgrade requirement. All compatibility and suitability assessments are subject to confirmation based on documentation provided.
