⚙️ Emerson Rosemount 3051TG / 3051CG / 3051S2TG Gauge Pressure Transmitter
Reliable Line and Tank Pressure Measurement
Gauge pressure transmitters are essential for monitoring line and tank pressures in industrial processes. Emerson Rosemount 3051 series models — 3051TG, 3051CG, and 3051S2TG — deliver high accuracy, long service life, and global certifications, making them trusted solutions in process automation worldwide.
This guide covers the technical features, operating principles, and full product code explanations for Rosemount gauge pressure transmitters.
🔎 Meaning of Model Codes
Rosemount gauge pressure transmitter codes indicate the type:
- GP (Gauge Pressure): Measures pressure relative to atmosphere.
- TG (Traditional Gauge): Standard gauge transmitter.
- CG (Coplanar Gauge): Coplanar connection gauge transmitter.
- S TG (Smart Gauge): Advanced gauge transmitter with enhanced electronics.
These codes are critical for selecting the correct configuration during procurement.

⚙️ Operating Principle
Gauge pressure transmitters work as follows:
- Pressure detection – Line or tank pressure is sensed.
- Atmospheric reference – Measurement is compared against atmospheric pressure.
- Signal conversion – Value is converted to 4–20 mA, HART, or digital protocol.
- System integration – Signal is transmitted to DCS/PLC systems.
Applications include:
- Line pressure monitoring
- Tank pressure control
- Pump and pipeline pressure tracking
🏭 Application Areas
- ⚡ Power plants: Steam line pressure monitoring
- 🛢️ Petrochemical & Refinery: Tank and pipeline pressure measurement
- 💧 Water & Wastewater: Pump and tank pressure monitoring
- 🔧 General process automation: Line and tank pressure applications
