Frequently Asked Questions – Rosemount 3051CG

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

The 3051CG measures gauge pressure, which is the pressure relative to atmospheric pressure.

2. What is the accuracy of the 3051CG?

It offers up to ±0.04% of span reference accuracy, making it ideal for precision-critical applications.

3. What output protocols are supported?

  1. 4–20 mA HART®
  2. FOUNDATION™ Fieldbus
  3. Profibus®
  4. WirelessHART®
  5. Low-power voltage output (select models)

4. What is the maximum pressure range?

Depending on the range code, it can measure up to 6000 psi (413 bar).

5. What’s the difference between the 3051CG and 3051CA?

  • 3051CG: Measures gauge pressure using a capacitance sensor.

  • 3051CA: Measures absolute pressure using a piezoresistive silicon sensor.

6. How much does the 3051CG weigh?

Approximately 5.7 lbs (2.6 kg) without mounting brackets.

7. Can it be used in hazardous environments?

Yes, it has multiple certifications, including SIL 2/3, explosion-proof, and intrinsically safe approvals.

8. What mounting options are available?
