2088A1A02A1AB4 • Absolute Pressure • ½" NPT • 316L SS • 4–20 mA HART® • IP66 • Steam and vacuum applications
2088A3A05F1AB4 • Absolute Pressure • 1" ANSI Flange • FOUNDATION™ Fieldbus • 316L SS • NEMA 4X / IP66 • DCS integrated process plants
📑 Note: Model codes must be verified using Emerson technical documentation and Rosemount datasheets. Final configuration should be determined according to process conditions.
The Rosemount 2088A measures process pressure relative to absolute vacuum instead of atmosphere.
The value detected by the pressure sensor is processed in the electronic sensor cell, temperature compensation is applied and converted into a high‑accuracy digital measurement.
Measurement data is transmitted via:
4–20 mA
HART®
FOUNDATION™ Fieldbus
PROFIBUS PA
to PLC, DCS and SCADA systems.
