The DEIF DLQ 144-PC-PY is a panel-mounted bar meter produced under the STN Atlas and DEIF brand portfolio, designed to provide clear, continuous pressure indication within marine control systems. Accepting a standard 4–20mA analogue input across a measurement range of 0 to 40 bar, this instrument converts process signals into a readable bar-graph or pointer display directly on the control panel fascia. Onboard vessels, accurate pressure monitoring is essential to safe and efficient machinery operation, making instruments of this type a critical component in engine room and machinery control consoles.
Key Features
✓ Measures pressure across a 0 to 40 bar range via a 4–20mA analogue input signal, with a loop load of less than 4.5 Ω, compatible with standard transmitter outputs found throughout marine installations.
✓ Panel illumination operates on 24VAC/DC, consistent with the low-voltage DC supplies commonly distributed across marine control and monitoring panels.
✓ Designed to the DLQ 144 form factor, indicating a 144mm panel-cut instrument — a widely adopted standard size for integration into existing control console cutouts without modification.
✓ Suitable for installation within enclosed control stations, engine control rooms, and machinery monitoring panels; mounting environment and ingress protection rating should be confirmed against vessel-specific requirements.
✓ As a direct-replacement instrument, it is suited to like-for-like substitution in existing STN Atlas or DEIF-equipped panels, subject to confirmation of signal compatibility and dimensional fit.
Marine Applications
✓ Engine control room panels monitoring lube oil, fuel oil, or cooling water pressure across main and auxiliary machinery systems.
✓ Integrated automation and monitoring systems on merchant vessels including bulk carriers, tankers, container ships, and general cargo vessels.
✓ Offshore support vessels and platform supply vessels where centralised machinery monitoring requires reliable analogue display instrumentation.
✓ Pump control and ballast system panels where continuous pressure indication is required to support safe operational decision-making.
✓ Retrofit and upgrade projects on vessels with legacy DEIF or STN Atlas control systems requiring replacement panel instruments to match original specifications.
Why Marine Engineers Choose
The DEIF DLQ 144-PC-PY offers a known-specification, standardised analogue bar meter that integrates directly into existing marine control panel infrastructure. Its defined input range, low loop load, and standard illumination voltage reduce commissioning complexity during replacement or retrofit, making it a practical choice for vessel operators and service engineers working to minimise machinery downtime.
Ideal For
Merchant fleet operators, offshore vessel managers, ship repair yards, and marine electrical contractors maintaining or upgrading DEIF and STN Atlas control systems across a broad range of commercial, offshore, and industrial vessel types.
Technical Support & Compliance
Remote troubleshooting guidance, commissioning support, and integration assistance are available to help confirm suitability and facilitate installation, subject to confirmation. To verify compatibility with your existing panel or control system, buyers are encouraged to share nameplate photographs, the original part number or drawing reference, the panel or system model and software version where applicable, and vessel name or IMO number. Scope of supply, exact specifications, and any applicable approvals should be confirmed prior to order to ensure the instrument meets your installation requirements.
