Rosemount 3051S vs. 3051 Pressure Transmitters: Accuracy, Stability, and Selection

The Emerson Rosemount 3051 and 3051S are widely used pressure transmitter families for industrial process measurement.

Both support pressure measurement applications in oil and gas, chemical processing, power generation, and other process industries.

The 3051S is designed for applications requiring higher performance and long-term measurement stability, while the 3051 offers a versatile solution for general industrial pressure measurement.

Actual performance depends on the selected sensor range, configuration, and ordering code.

The Rosemount 3051 is designed for a broad range of gauge, absolute, and differential pressure measurement applications.

Its main advantages include:

• Multiple pressure measurement configurations.

• Flexible communication options.

• Process alerts and diagnostic functions.

• Options for remote display and different installation arrangements.

It is a practical choice for general plant instrumentation and pressure monitoring applications.

The Rosemount 3051S features Emerson's SuperModule design and is intended for applications where measurement performance and long-term stability are important.

Selected 3051S configurations also provide multivariable measurement of differential pressure, static pressure, and process temperature.

This can reduce the number of separate instruments and process connections required in certain flow measurement applications.

However, not every 3051S configuration is a multivariable transmitter. Buyers should specify the required measurement type and model configuration.

Choose the Rosemount 3051 for general industrial pressure measurement where its performance and configuration meet the process requirements.

Consider the 3051S for applications requiring higher reference accuracy, longer-term stability, or specialized multivariable measurement.

Before ordering, confirm:

• Gauge, absolute, or differential pressure.

• Required measurement range and calibration range.

• Operating and static pressure.

• Process temperature.

• Wetted materials and process connections.

• Output signal and communication protocol.

• Remote seal or manifold requirements.

• Hazardous-area certifications.
