2088G2A22A1AB4 • Gauge Pressure • 2" DIN Flange • 316L SS • 4–20 mA HART® • NEMA 4X / IP66 • General process pipelines
2088G4A2B21P1AB4 • Gauge Pressure • ½" NPT • Hastelloy diaphragm • PROFIBUS PA • Stainless Steel Housing • Corrosive processes and offshore applications
📑 Note: Model codes must be verified using Emerson technical documentation and Rosemount datasheets. Final configuration should be determined according to process conditions.
The Rosemount 2088G measures process pressure relative to atmospheric pressure.
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.
