Product Description

Emerson Rosemount 3051CD Stainless Steel Shell Pressure Transmitter

The Emerson Rosemount 3051CD Stainless Steel Shell Pressure Transmitter is a high-precision, durable solution engineered to deliver accurate and reliable pressure measurement in demanding industrial environments. Part of Emerson's renowned 3051 family, the 3051CD combines advanced capacitive sensor technology, robust stainless steel construction, and digital communication capabilities to meet the needs of critical processes across industries such as oil and gas, chemical processing, power generation, and water/wastewater treatment. Its stainless steel shell ensures exceptional resistance to corrosion, mechanical stress, and extreme environmental conditions, making it ideal for applications where durability and long-term performance are paramount.

Core Technology and Operating Principle
The 3051CD utilizes capacitive sensing technology to measure gauge or differential pressure with exceptional precision. The core of the transmitter is a silicon resonant sensor, which detects pressure-induced changes in capacitance and converts them into a proportional electrical signal. This design ensures high sensitivity and repeatability while minimizing drift over time. The transmitter's digital signal processing (DSP) further enhances performance by compensating for temperature variations, mechanical stress, and environmental noise, delivering stable readings even in dynamic process conditions.

A key innovation is the integration of HART 7 communication, enabling bidirectional digital communication over traditional 4–20 mA analog signals. This allows operators to remotely configure the device, perform diagnostics, and retrieve process data without interrupting operations. Optional FOUNDATION Fieldbus or PROFIBUS PA protocols provide seamless integration into modern control systems, supporting advanced process analytics and asset management strategies.

Technical Performance and Features
The 3051CD delivers exceptional accuracy and versatility:

Measurement Accuracy: ±0.065% of span, ensuring precise pressure monitoring for critical process control.
Pressure Range: Available from 0.15 psi to 400 psi (1 kPa to 2,758 kPa), accommodating applications from low-pressure ventilation systems to high-pressure industrial pipelines.

Advanced Diagnostic and Asset Management Features
The 3051CD incorporates predictive diagnostics to enhance operational reliability and reduce unplanned downtime. Key diagnostic capabilities include:

Sensor Health Monitoring: Detects sensor degradation, overpressure events, or abnormal drift, providing early warnings of potential failures.
Signal Integrity Checks: Identifies electrical noise, grounding faults, or wiring issues affecting measurement accuracy.
Device Health Alerts: Notifies operators of internal component failures, such as power supply anomalies or microprocessor errors.
These diagnostics are accessible via HART or digital communication protocols and can be integrated into Emerson's PlantWeb® digital ecosystem or other asset management systems like AMS Device Manager. This enables proactive maintenance planning, optimizing equipment uptime and reducing lifecycle costs.

Ease of Use and Integration
Installation and configuration of the 3051CD are streamlined through intuitive local and remote interfaces:

Local Configuration: A backlit LCD display with push-button controls allows on-site setup and troubleshooting without removing the transmitter from the process.
Remote Configuration: HART or digital protocols enable adjustments using handheld communicators, mobile devices, or control system interfaces.
Flexible Mounting Options: Compatible with direct-mount, flange-mount, or remote-seal configurations for adaptability to diverse piping systems.
The 3051CD's universal design supports multiple process connections (e.g., threaded, flanged, or sanitary) and integrates seamlessly with legacy 4–20 mA systems while supporting modern digital upgrades.

Applications Across Industries
The 3051CD's versatility makes it suitable for critical applications:

Oil and Gas: Monitoring pipeline pressure, wellhead pressure, and separator vessels in upstream, midstream, and downstream operations.
Chemical Processing: Ensuring precise pressure control in reactors, distillation columns, and storage tanks handling corrosive or reactive materials.
Power Generation: Measuring boiler pressure, turbine exhaust, and condenser pressure to optimize efficiency and prevent equipment damage.
