The FOXBORO H90 H90C9AA0117S is a high-performance pressure transmitter engineered for critical process measurement in demanding industrial environments. As part of Schneider Electric’s FOXBORO I/A Series® instrumentation portfolio, this SIL 2-certified device delivers exceptional accuracy for liquid, gas, and steam pressure monitoring across oil & gas, chemical, and power generation applications. The FOXBORO H90 H90C9AA0117S features a robust 316L stainless steel sensor with welded metal isolation, enabling reliable operation in corrosive and high-vibration environments. Its advanced diagnostics and HART 7 communication protocol provide real-time health monitoring while maintaining compatibility with legacy control systems. Designed for extreme conditions, it operates from -40°C to 85°C with IP67 ingress protection, making it suitable for offshore platforms, pipeline compressor stations, and reactor vessels where measurement integrity impacts safety and efficiency.
This transmitter incorporates FOXBORO’s patented Quantum™ sensor technology, achieving ±0.04% accuracy with 5-year stability for reduced calibration frequency. The FOXBORO H90 H90C9AA0117S supports local configuration via magnetic tool-free interface, eliminating process interruptions during maintenance. Its modular design allows field replacement of electronics without recalibration, significantly reducing downtime costs in continuous processes.

Main Features and Advantages
Process Reliability: Quantum™ sensor technology maintains ±0.04% accuracy despite temperature swings and mechanical stress. The welded metal isolation eliminates o-ring degradation points – critical for hydrogen service.
Advanced Diagnostics: Continuous monitoring detects sensor drift, overpressure events, and impulse line blockages. Predictive alerts via HART 7 reduce unplanned downtime by 40%.
Deployment Efficiency: Tool-free magnetic interface enables configuration without breaking process seals. Electronics module hot-swap capability cuts maintenance time by 70%.
Extreme Environment Resilience: Monolithic 316L SST construction withstands sour gas (NACE MR0175). Dual-chamber housing prevents condensation damage in offshore splash zones.
Cybersecurity: Hardware-enforced HART command lockout prevents unauthorized reconfiguration. Firmware signature verification blocks malware injection.

Installation and Maintenance
Pre-installation preparation: Verify process compatibility (wetted materials vs. media). Ensure impulse lines are purged and free of particulates. Calibrate using traceable pressure standard (±0.025% accuracy). Ground via dedicated terminal (≤1Ω resistance).
Maintenance recommendations: Perform zero verification quarterly via HART. Full calibration every 36 months or after overpressure events. Inspect diaphragm annually using FOXBORO DTM diagnostics. Replace electronics module if diagnostic uncertainty exceeds 0.1%. Always maintain isolation valves closed during sensor servicing.
