Emerson Rosemount 1151DP3S22B1 Pressure Transmitter

The Emerson Rosemount 1151DP3S22B1 Pressure Transmitter is a differential pressure transmitter in the Rosemount 1151 family, marketed as an AlphaLine Smart device for process measurement. It converts differential pressure across a flow element, filter, or other DP sensor into a standardized electrical signal for process control, typically delivering a 4-20 mA analog output suitable for connection to PLCs and DCS systems. The DP3S22B1 suffix identifies this exact variant within the AlphaLine Smart series, reflecting Emerson's configuration for this model and ensuring compatibility with the Rosemount measurement ecosystem. Designed for industrial environments, this transmitter supports common applications such as monitoring pressure drops across valves, orifice plates, or filters to infer flow, detect fouling or blockages, and track system performance. The Rosemount name signifies a long lineage of industrial instrumentation, and the 1151DP3S22B1 is a representative option for teams seeking a differential pressure monitoring solution in sectors like oil and gas, chemical processing, water treatment, and power generation.
