Frequently Asked Questions – Rosemount 3051CG

1. What does the 3051CG measure?

It measures gauge pressure, which is pressure relative to atmospheric pressure, using Emerson’s Coplanar™ platform for flexible integration.

2. What is the pressure range?

It supports a wide span—from 25 inH₂O to 2000 psi (1.72 mbar to 137.89 bar), depending on the selected sensor range.

3. What is the reference accuracy?

It offers ±0.04% of span accuracy, with a 150:1 turndown ratio, ensuring precise performance across a wide range of applications.

4. What output protocols are available?

1. 4–20 mA HART®
2. WirelessHART®
3. FOUNDATION™ Fieldbus

5. What mounting style does it use?

The 3051CG uses a Coplanar flange, allowing direct mounting to manifolds or remote diaphragm seals.

6. What are typical applications?

1. Tank level monitoring
2. Pump discharge pressure
3. Hydraulic and pneumatic systems
4. Process pressure in sealed systems

7. Is it SIL certified?

Yes, it is SIL 2/3 certified per IEC 61508, making it suitable for Safety Instrumented Systems (SIS).

8. What diagnostics are included?

It features:

1. Loop Integrity Diagnostics
2. Plugged Impulse Line Detection
