The Rosemount 3051S2TG Pressure Transmitter is a state-of-the-art industrial instrument engineered to deliver unparalleled precision, reliability, and versatility in pressure measurement for critical applications across industries such as oil and gas, chemical processing, power generation, water treatment, and pharmaceuticals. As part of the globally recognized Rosemount 3051S Series, this transmitter combines advanced sensor technology, robust construction, and intelligent diagnostics to optimize process efficiency, safety, and operational continuity in even the most demanding environments.
Core Technology and Design Philosophy
The 3051S2TG leverages Rosemount's decades of expertise in pressure measurement, incorporating a next-generation capacitive silicon sensor optimized for gauge pressure applications. This sensor design employs a single-crystal silicon element that deflects minimally under pressure, converting mechanical stress into highly linear electrical signals. The sensor's hermetic isolation via oil-filled chambers ensures immunity to moisture, particulates, and corrosive media, while its temperature-compensated circuitry minimizes thermal errors across the entire operating range.
The transmitter's dual-compartment housing, constructed from 316L stainless steel with optional Hastelloy C-276 or alloy 625 overlays, provides exceptional resistance to pitting, crevice corrosion, and sulfide stress cracking. This design is further enhanced by a welded, torsion-resistant process flange that eliminates potential leak paths and ensures long-term integrity under high-cycle fatigue conditions.
Performance Specifications

The 3051S2TG integrates Rosemount's proprietaryPlantWeb®ecosystem, providing predictive maintenance insights and real-time health monitoring through:
Embedded Diagnostics: Continuous assessment of sensor integrity, electronics stability, and process connection integrity.
Plugged Impulse Line Detection: Advanced algorithms identify blockages in impulse lines using statistical process deviation analysis.
Process Noise Monitoring: Spectral analysis of sensor output detects abnormal turbulence, cavitation, or two-phase flow conditions.
Communication Health Metrics: End-to-end signal integrity checks for HART, FOUNDATION Fieldbus, or PROFIBUS PA networks.
Diagnostic results are communicated via customizable PlantWeb Alerts, which prioritize issues based on severity and recommend corrective actions through AMS Device Manager or control system interfaces.
Hazardous Area Certifications
The 3051S2TG meets global standards for intrinsic safety, flameproof enclosures, and non-incendive protection:
ATEX/IECEx: Ex ia IIC T6 Ga (Zone 0/1), Ex d IIC T6 Gb (Zone 1/2).
FM/FMc: Class I, Div 1, Groups A-D; Class II/III, Div 1, Groups E-G; T6 rating.
CSA: Class I, II, III, Div 1, with optional Canadian Registration Number (CRN) for pressure boundary compliance.
