Introduction:

The Rosemount 3051CD is a highly accurate and durable differential pressure transmitter designed for demanding industrial applications, offering exceptional precision (±0.04% of span), long-term stability, and versatile integration through its Coplanar™ platform. Ideal for flow, level, and filter monitoring, it supports HART®, Fieldbus, and WirelessHART® communication, making it a trusted choice across industries like oil & gas, chemical, and water treatment.

Rosemount 3051 Series Comparison Guide

Model Measurement Type Pressure Range Mounting Style Key Features
3051CD Differential Pressure ±0.1 inH₂O to ±2000 psi Coplanar™ High accuracy (±0.04%), 10-year stability, ideal for flow/level applications
3051CG Gage Pressure Up to 2000 psi Coplanar™ Measures pressure relative to the atmosphere, same platform as CD
3051CA Absolute Pressure Up to 4000 psia Coplanar™ For vacuum or sealed systems, use a piezoresistive sensor
3051T Gage/Absolute Pressure Up to 10,000 psi In-Line Compact, rugged, ideal for high-pressure pipelines
3051L Level (DP-based) Up to 300 psi Direct/Remote Mount Tuned-System™ assemblies for tanks include capillary options
3051CF Flow (DP-based) Application-specific Integrated w/Primary Combines DP transmitter with flow element (e.g., Annubar™, orifice plate)

Selection Tips

  1. Choose 3051CD for most differential pressure needs, especially when integrating with manifolds or measuring flow.
  2. Use 3051T when space is tight or pressure is extreme.
  3. Opt for 3051L when measuring level in pressurized or vacuum tanks.
  4. For flow-specific setups, 3051CF offers a pre-engineered, leak-tested solution.

Rosemount 3051CD – Frequently Asked Questions

1. What does the 3051CD measure?

It measures differential pressure (ΔP)—the difference between two pressure points—commonly used for flow, level, and filter monitoring.

2. What’s the accuracy of the 3051CD?

Standard accuracy is ±0.075% of span, with options as tight as ±0.04% for high-performance applications.

3. What is the pressure range?

It covers a wide range from ±0.1 inH₂O to ±2000 psi, depending on the selected sensor range.

4. What communication protocols are supported?

  1. 4–20 mA with HART®
  2. FOUNDATION™ Fieldbus
  3. WirelessHART® (optional)

5. What is Coplanar™ technology?

It’s Emerson’s patented design that allows for compact, integrated mounting with manifolds and seals—ideal for space-saving and modular installations.

6. Can it be used in hazardous environments?

Yes. It’s certified for use in explosion-proof, intrinsically safe, and non-incendive environments (ATEX, IECEx, FM, CSA, etc.).

7. How stable is it over time?

It offers 10-year stability of ±0.2% of URL, reducing recalibration needs and maintenance costs.

8. What diagnostics are built in?

  1. Loop Integrity Check
  2. Plugged Impulse Line Detection
  3. Process Alerts for early issue detection

9. What materials are available for wetted parts?

Standard is 316L stainless steel, with options like Alloy C-276, Tantalum, or Gold-plated materials for corrosive media.

10. How do I install and configure it?

It can be configured via a HART communicator, AMS Device Manager, or Field Communicator. Installation requires proper impulse line routing and electrical grounding per the manual.
