Emerson Rosemount 1144G0120A12 Pressure Transmitter

Emerson Rosemount 1144G0120A12 Pressure Transmitter is a legacy Rosemount instrument that converts process pressure into an electrical signal for continuous monitoring and control in industrial facilities. The device senses pressure from a connected process line and provides a standardized output that can be integrated with DCS, PLC, or other instrumentation for real-time supervision, alarming, and data logging. As part of the Rosemount family, the 1144G0120A12 variant represents a specific configuration within the 1144 series, designed for compatibility with Emerson’s measurement ecosystem and the broader Rosemount instrumentation lineup. Common applications include monitoring pressure in chemical processing, refining, water and wastewater treatment, oil and gas upstream and downstream operations, and power generation systems, where stable, long-term performance is essential in demanding environments. The transmitter is suited for use in retrofit and upgrade projects, enabling reliable pressure measurement within existing control architectures while leveraging Rosemount’s legacy reliability and compatibility.
