Description

The GE 339-E-P5-G5-H-E-S-N-N-3E-D-N is a high-accuracy multivariable pressure transmitter designed for demanding industrial applications requiring simultaneous measurement of differential pressure (DP), static pressure, and process temperature—enabling direct mass or energy flow computation without external sensors. As part of GE’s (now Baker Hughes) renowned 339 series, this model integrates three sensing elements into a single compact housing, significantly reducing installation complexity and cost compared to traditional multi-instrument setups. The GE 339-E-P5-G5-H-E-S-N-N-3E-D-N delivers a primary 4–20 mA output proportional to differential pressure, with full digital access via HART protocol to all measured variables, making it ideal for custody transfer, boiler efficiency monitoring, and natural gas pipeline metering.

Engineered for reliability in harsh environments, the 339-E-P5-G5-H-E-S-N-N-3E-D-N features a rugged stainless steel enclosure rated IP66/NEMA 4X and includes built-in surge protection compliant with IEC 61000-4-5. Its dual-isolated electronics architecture ensures signal integrity even in electrically noisy plants such as refineries or power stations. With an accuracy of ±0.075% of span on DP and ±0.1% on static pressure, the GE 339-E-P5-G5-H-E-S-N-N-3E-D-N meets stringent requirements for fiscal metering and regulatory compliance. Fully compatible with major asset management platforms—including Emerson AMS, Yokogawa PRM, and GE Proficy—the device supports remote configuration, calibration verification, and predictive diagnostics, minimizing site visits and enhancing operational safety.

Technical Specifications

Main Features and Advantages

True multivariable measurement in a single device:
Unlike conventional DP transmitters that require separate static pressure and temperature sensors for compensated flow calculations, the GE 339-E-P5-G5-H-E-S-N-N-3E-D-N integrates all three measurements internally. This eliminates alignment errors, reduces impulse line complexity, and cuts installation time by up to 40%. The onboard microprocessor computes fully compensated mass flow (e.g., for steam or natural gas) using AGA, API, or ISO standards—delivering engineering units directly over HART without external flow computers.

Unmatched stability and diagnostic intelligence:
The 339-E-P5-G5-H-E-S-N-N-3E-D-N employs GE’s patented silicon resonant sensor technology, offering long-term stability of <±0.1% per year—critical for applications where recalibration downtime is costly. Advanced self-diagnostics monitor sensor health, ambient conditions, and loop integrity, flagging issues like plugged impulse lines, grounding faults, or electronic drift before they cause process deviations. These alerts are accessible via HART handhelds or asset management systems, enabling condition-based maintenance.

Robust design for global hazardous areas:
Certified for use in Zone 1/2 and Class I Div 1/2 hazardous locations, the GE 339-E-P5-G5-H-E-S-N-N-3E-D-N meets international safety standards including ATEX, IECEx, and CSA. Its dual-compartment housing separates electronics from process connections, enhancing safety and simplifying wiring. Integrated transient protection (6 kV/3 kA) safeguards against lightning-induced surges—essential for offshore platforms and rural pipelines. The modular design also allows field replacement of the electronics module without re-pressurizing the process.

Application Field

The GE 339-E-P5-G5-H-E-S-N-N-3E-D-N excels in applications where accurate, compensated flow or level measurement is critical to safety, efficiency, or revenue assurance. In natural gas transmission and distribution networks, it serves as the core of fiscal metering skids, providing AGA-compliant mass flow calculations using real-time DP, static pressure, and temperature—eliminating the need for separate transmitters and reducing uncertainty in billing. Similarly, in steam systems at power plants or district heating facilities, the 339-E-P5-G5-H-E-S-N-N-3E-D-N enables precise energy flow tracking for efficiency optimization and emissions reporting.

In oil & gas production, the GE 339-E-P5-G5-H-E-S-N-N-3E-D-N is deployed on wellhead test separators and multiphase flow meters to monitor phase-specific flow rates under varying backpressure conditions. Its ability to withstand wide ambient temperature swings and resist corrosion makes it suitable for desert, arctic, and offshore installations. In chemical and petrochemical plants, it supports reactor level control, distillation column pressure profiling, and flare gas monitoring—often in SIL 2 safety instrumented functions (SIFs). By consolidating three measurements into one certified device, the 339-E-P5-G5-H-E-S-N-N-3E-D-N not only lowers capital expenditure but also enhances data coherence and system reliability across the entire automation lifecycle.

Installation and Maintenance

Pre-installation preparation: Mount the GE 339-E-P5-G5-H-E-S-N-N-3E-D-N with impulse lines properly sloped to prevent liquid traps (for gas) or gas pockets (for liquid). Use equal-length, same-diameter tubing for high/low sides to minimize thermal imbalance. Ensure the process flanges match the specified rating (e.g., 150# or 300# RF). Power the loop with 24 VDC and verify HART communication using a standard communicator before pressurization. For custody applications, perform a zero trim after installation but before process startup.

Maintenance recommendations: The GE 339-E-P5-G5-H-E-S-N-3E-D-N requires no routine calibration if operating within specified conditions, thanks to its high stability. However, annual verification using a HART communicator is recommended for fiscal or safety-critical loops. Monitor diagnostic flags for sensor health, ambient temperature excursions, or loop resistance anomalies. Clean the vent/drain plugs periodically to prevent clogging. If the electronics module fails, it can be replaced in the field without depressurizing the process—simply unbolt the top housing and swap the module, then re-upload configuration from backup.
