Product Overview
The Foxboro H90 H90C9AA0117S is a high-precision differential pressure transmitter designed for critical process measurement in demanding industrial environments. Part of Foxboro’s (a Schneider Electric company) renowned H90 series, this device delivers exceptional accuracy for monitoring pressure, level, and flow in oil & gas, chemical processing, and power generation applications. The Foxboro H90 H90C9AA0117S features a robust 316L stainless-steel sensor capsule with SIL 2 certification, ensuring compliance with IEC 61508/61511 safety standards. Its advanced capacitive sensing technology achieves ±0.075% accuracy across a wide measurement range (0-100 mbar to 0-400 bar), making it ideal for both low-pressure and high-pressure scenarios.
Engineered for reliability, the Foxboro H90 H90C9AA0117S integrates HART 7 and Foundation Fieldbus protocols for seamless communication with DCS/PLC systems. The transmitter’s modular design allows for in-situ calibration and diaphragm replacement without process interruption, minimizing downtime. With IP66/IP68 protection and a -40°C to +85°C operating range, the Foxboro H90 H90C9AA0117S excels in offshore platforms, cryogenic storage, and high-vibration installations. Its corrosion-resistant construction and optional ATEX/IECEx certifications further enhance suitability for hazardous areas.
