Rosemount 3051S1CG4A2B11A1 Scalable Coplanar Gage Pressure Transmitter with Local Display

The Rosemount 3051S1CG4A2B11A1 is a high-performance scalable coplanar gage pressure transmitter designed for level measurement applications in industrial settings. It features a robust design with a local operator interface (LOI) display for easy on-site configuration and diagnostics. This model includes a 3-inch flange connection, making it suitable for tank and vessel level monitoring in processes such as oil and gas, chemical processing, and water treatment. Key benefits include exceptional accuracy of up to 0.04% of span, advanced diagnostics for predictive maintenance, and compatibility with FOUNDATION Fieldbus and 4-20 mA HART protocols. It offers superior stability and reliability over traditional transmitters, reducing downtime and maintenance costs. Drawbacks may include higher initial cost compared to basic models and the need for compatible mounting hardware. The unit supports a wide pressure range and is built with stainless steel wetted parts for corrosion resistance. From the provided images, the transmitter appears to be in used but good condition, with minor cosmetic wear; no visible damage to critical components. Serial number visible as 21050653 on one label. Includes integral display and appears to have an attached diaphragm seal or flange assembly as a child asset for direct tank mounting. Estimated market price range for used units: $800-$1500 USD, based on comparable eBay and industrial surplus listings.
