Description

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.

Technical Specifications

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.
