Product Description

3051CD Low Pressure Transmitter

2.5 lbs 3051CD Low Pressure Transmitter /- 0.075% Accuracy 0

Introduction:

The Rosemount 3051CD is a high-precision differential pressure transmitter engineered for low-pressure applications. Built on Emerson’s Coplanar™ platform, it delivers exceptional accuracy (±0.04% of span) and long-term stability, making it ideal for critical measurements in flow, level, and filter monitoring systems.

With a wide turndown ratio (up to 150:1) and support for multiple communication protocols like HART®, WirelessHART®, and FOUNDATION Fieldbus, the 3051CD offers flexible integration into modern process control systems. Its robust design, diagnostic capabilities, and material options ensure reliable performance even in harsh industrial environments.

Selection Tips

  1. Choose 3051CD for low differential pressure applications like filter monitoring or flow across orifice plates.
  2. Use 3051CG when measuring gauge pressure in tanks or pipelines.
  3. Opt for 3051CA for absolute pressure in vacuum or sealed systems.
  4. Select 3051S when ultra-high accuracy, diagnostics, or scalability are critical.

Frequently Asked Questions – Rosemount 3051CD

1. What type of pressure does the 3051CD measure?

The 3051CD is a differential pressure transmitter, ideal for measuring the pressure difference between two points in low-pressure applications.

2. What is the minimum pressure range it can detect?

It can measure as low as ±3 inH₂O (±7.46 mbar), making it suitable for ultra-low pressure monitoring like cleanrooms or filter diagnostics.

3. How accurate is the 3051CD?

It offers a reference accuracy of ±0.04% of span, with long-term stability of ±0.2% of URL over 10 years.

4. What communication protocols are supported?

The transmitter supports 4–20 mA HART®, WirelessHART®, FOUNDATION Fieldbus, Profibus, and low-power HART® options.

5. Can I install and commission it before wiring?

Yes. The 3051CD can be commissioned before or after installation, offering flexibility during setup.

6. What diagnostics are included?

It features Loop Integrity and Plugged Impulse Line diagnostics to detect wiring issues or blockages in impulse lines.

7. Is it suitable for hazardous environments?

Yes. It carries certifications such as SIL 2/3, ATEX, IECEx, FM, CSA, and NEPSI, making it safe for use in explosive or corrosive environments.

8. What materials are available for wetted parts?

Standard is 316L stainless steel, with options for Alloy C-276, Tantalum, and others for corrosive media compatibility.

9. Can I use it for level or flow measurement?

Absolutely. When paired with a primary element or diaphragm seal, it can be used for DP flow or level measurement in pressurized vessels.

10. How do I configure the transmitter?

You can use a HART communicator, AMS Device Manager, or Local Operator Interface (LOI) for setup and diagnostics.
