Emerson 3051CD2A22A1AK5M5S8D4 Pressure Transmitter

The Emerson Rosemount 3051CD2A22A1AK5M5S8D4 Coplanar Differential Pressure Transmitter is a rugged Rosemount 3051 series device that converts differential pressure into a scalable 4–20 mA output with HART communication for process control. It covers a differential pressure range of -250 to 250 inches of water, making it suitable for level, flow, and DP measurements across challenging industrial environments; the unit uses 316L stainless steel wetted parts, a glass-filled PTFE O-ring, and silicone fluid, and is housed in an aluminum enclosure with a local LCD readout option (M5). The electrical conduit entry is 1/2-14 NPT, supporting robust field mounting and wiring in harsh plants, while field communications allow remote sensor configuration and diagnostics via HART. Typical applications include oil and gas processing, chemical manufacturing, power generation, and water/wastewater treatment where accurate differential pressure readings are needed for level control, flow measurement, and differential pressure monitoring.
