ROSEMOUNT 3051S Product Description

The ROSEMOUNT 3051S is a scalable smart pressure transmitter built upon the patented SuperModule™ architecture, delivering premium performance for industrial process measurement and control. This pressure transmitter supports differential, gauge, absolute and multivariable pressure measurement, covering flow, liquid level, tank pressure and pipeline monitoring across heavy industries. The pressure transmitter adopts fully welded hermetic construction, which effectively resists overpressure, line pressure interference and medium corrosion in severe working environments. The pressure transmitter provides outstanding long-term stability of up to 15 years and carries a 15-year limited warranty, greatly lowering periodic calibration and replacement frequency for plant operators.

This ROSEMOUNT series features the well-known Coplanar™ design, which cuts installation steps and reduces potential leak points when matched with manifolds or remote seal assemblies. Its high-precision pressure sensor minimizes measurement drift caused by temperature swings and pressure fluctuations, maintaining consistent accuracy during continuous production cycles. The pressure sensor inside converts physical pressure changes into standard electrical signals, compatible with 4-20mA HART, WirelessHART and FOUNDATION fieldbus communication protocols. On-site configuration and calibration of the pressure sensor can be finished via handheld communicators or digital asset management software without removing the unit from the pipeline. The robust pressure sensor supports a wide 200:1 turndown ratio, allowing one transmitter model to satisfy multiple measurement range requirements for flexible project design.

The ROSEMOUNT 3051S has obtained SIL 2/3 functional safety certification complying with IEC 61508, suitable for safety instrumented systems in high-risk production sites. Reliable process monitoring helps operators capture real-time operating status and trigger early warnings for impulse line blockage, loop failure and abnormal medium conditions. Accurate process monitoring enables fine-tuning of production parameters, improves product quality and enhances overall plant operational safety. Real-time process monitoring data is transmitted to distributed control systems for remote asset management and predictive maintenance scheduling. Stable process monitoring performance effectively reduces unplanned shutdown incidents and optimizes total operational expenditure for chemical, oil & gas, power, pulp and paper industries.

Additional built-in intelligent diagnostic functions extend device health visibility, detecting hidden faults before measurement deviation occurs. Wetted material options include 316L stainless steel, Alloy C-276, Alloy 400 and tantalum to adapt to corrosive liquids, gas and steam media. Users can choose wired or wireless versions according to field layout; the wireless variant removes expensive field wiring work and achieves over 99% data transmission reliability. Pre-assembled flow assemblies are available for fast commissioning, fully leak-tested and calibrated before shipment to shorten site construction time. Whether used for high static pressure pipelines, low-level tank measurement or custody transfer flow calculation, ROSEMOUNT 3051S remains a trusted choice for demanding industrial automation applications worldwide.
