⚙️ Emerson Rosemount 2051TG / 2051TA Coplanar Pressure Transmitter \| Technical Guide, Model Codes and Price Advantage
Reliable Coplanar Pressure Measurement
The Rosemount 2051TG and 2051TA series provide direct process connection with coplanar body design.
- 2051TG: Used for gauge pressure measurement.
- 2051TA: Used for absolute pressure measurement.
Compared to other transmitter families, these coplanar models are preferred in compact mounting and manifold integration applications. They deliver high accuracy, long‑term stability, and low maintenance cost.
