Industrial operations depend on pressure measurement for everything from flow control and level monitoring to energy management and system safety. When accuracy can impact production quality, safety compliance, and overall plant efficiency, choosing the right transmitter is essential.

The 3051S Pressure Transmitter is widely regarded as one of the most advanced and reliable pressure transmitters available today. Built on a high-performance platform with exceptional long-term stability, advanced diagnostics, and flexible configurations, it is engineered for applications where precision and reliability cannot be compromised.

What Is the 3051S Pressure Transmitter?

The 3051S is a premium performance transmitter designed to measure:

• Differential pressure (DP)

• Gauge pressure (GP)

• Absolute pressure (AP)

• Level (hydrostatic DP measurement)

• DP-based flow measurement

Its intelligent architecture and robust design make it suitable for harsh environments, high-pressure systems, hazardous locations, and mission-critical industrial processes.

How the 3051S Works

The 3051S transmitter measures pressure using an extremely stable piezoresistive sensor paired with advanced digital signal conditioning.

1. Process pressure is applied to a high-precision diaphragm.

2. The diaphragm deflects, altering the resistance of piezoresistive elements.

3. These changes are converted into a proportional electrical signal.

4. Smart electronics compensate for temperature, pressure, and mechanical factors.

5. The final output is delivered via 4–20 mA, HART®, Fieldbus™, Profibus, or WirelessHART®.

This advanced sensing and compensation technology delivers high-resolution, low-noise, drift-free measurement in real-world industrial conditions.
