The Rosemount 3051 is a differential pressure-based level transmitter with integrated sensor, designed to deliver accurate and reliable liquid level measurement across a wide range of marine control system applications. Calibrated from 0 to 250 inches H2O with a standard 4-20mA output and a broad supply voltage range of 0.5 to 55 VDC, this transmitter is well suited to continuous process monitoring aboard commercial and industrial vessels. Constructed in 316 stainless steel with a DN50 PN40 process connection, it is built to withstand demanding shipboard environments where corrosion resistance and mechanical integrity are essential to safe operations.
Key Features
✓ Provides continuous level measurement via differential pressure sensing, with a 4-20mA analogue output signal for direct integration with marine control and monitoring systems.
✓ Specified supply voltage range of 0.5–55 VDC and a calibration span of 0 to 250 inches H2O with a maximum working pressure of 9 PSI, as stated on the nameplate.
✓ DN50 PN40 process connection in 316 stainless steel construction, offering robust corrosion resistance suitable for seawater-adjacent or chemically aggressive tank environments.
✓ Compatible with distributed control systems, PLCs, and vessel monitoring panels that accept standard 4-20mA loop-powered transmitter signals — specific system compatibility subject to confirmation.
✓ Suitable for installation in tank tops, void spaces, or process pipework where reliable level data is critical to ballast management, cargo monitoring, or machinery space oversight.
Marine Applications
✓ Ballast tank level monitoring on bulk carriers, tankers, and general cargo vessels where accurate draft and stability management is operationally critical.
✓ Fuel oil and fresh water tank level measurement in machinery spaces, integrated with vessel management or alarm monitoring systems.
✓ Cargo hold or slop tank level sensing on chemical tankers and product carriers requiring continuous process feedback.
✓ Bilge well and grey water tank level control on offshore support vessels, RoPax ferries, and cruise ship auxiliary systems.
✓ Process level measurement in marine industrial installations, including desalination plant feed tanks, cooling water systems, and engine room day tanks.
Why Marine Engineers Choose
The Rosemount 3051 series is widely recognised for long-term measurement stability, robust stainless steel construction, and straightforward loop integration — making it a dependable choice for level monitoring in critical marine control system roles where sensor reliability directly supports safe vessel operation.
Ideal For
Tankers, bulk carriers, offshore support vessels, RoPax and cruise vessels, dredgers, and any commercial or industrial ship requiring accurate continuous level measurement within an automated monitoring or control system.
Technical Support & Compliance
Remote troubleshooting, onboard commissioning support, loop testing, and retrofit or replacement assistance are available for this transmitter, subject to confirmation. For integration into an existing control or alarm system, buyers are advised to share nameplate photographs, the full part number and revision, process connection details, system model and software version, applicable vessel name and IMO number, and the intended installation scope. Compatibility with specific panels, controllers, or monitoring platforms is subject to confirmation based on the information provided.
