RH924WA FOXBORO DCS Module Explosion Proof Stainless Pressure Transmitter

The Foxboro RH924WA is a high-accuracy industrial pressure transmitter engineered for critical process measurement in extreme industrial environments. Part of Foxboro's renowned RH Series, this transmitter features a robust 316L stainless steel housing with IP67/IP68 protection, ensuring reliability in harsh conditions like chemical exposure, high humidity, and submersion. Utilizing advanced piezoresistive sensor technology, it delivers precise gauge, absolute, or differential pressure readings across ranges from 0-10 kPa to 0-100 MPa. The RH924WA supports 4-20 mA analog output with HART® 7 protocol integration, enabling seamless communication with distributed control systems (DCS) like Foxboro I/A Series. Designed for oil and gas, power generation, and chemical processing, its modular electronics allow field calibration without process interruption.

• Measurement Range: 0-10 kPa to 0-100 MPa (field-adjustable)
• Accuracy: ±0.075% of span (incl. linearity, hysteresis, repeatability)
• Output: 4-20 mA analog + HART® 7 digital communication
• Process Connection: ¼" NPT, ½" NPT, or DIN flanges
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Pressure Rating: 400 bar (5800 psi) burst pressure
• Wetted Materials: 316L SS diaphragm; Hastelloy® C-276 optional
• Certifications: SIL 2/3 (IEC 61508), ATEX/IECEx Zone 0/1, CE, RoHS
• Long-Term Stability: <±0.1% URL/year
• Electrical Protection: Reverse polarity/surge protection

The RH924WA excels in mission-critical industrial processes:

• Oil & Gas: Wellhead pressure monitoring, pipeline leak detection, and separator vessel control
• Chemical Processing: Reactor overpressure protection, distillation column optimization
• Power Generation: Steam header pressure control, turbine inlet monitoring
• Pharmaceutical: Bioreactor sterilization validation (CIP/SIP compliance)
• Water Treatment: Pump protection and filter differential pressure sensing

Its ATEX/IECEx Zone 0 certification and SIL 3 safety rating make it ideal for hazardous areas and safety-instrumented systems (SIS).

• Ultra-High Accuracy: ±0.075% precision reduces product loss in custody transfer
• Extreme Durability: 316L/Hastelloy® construction resists pitting, corrosion, and chemical erosion
• Smart Diagnostics: HART® 7 enables predictive maintenance (sensor drift/overpressure alerts)
• Safety Compliance: SIL 3 certification for functional safety-critical applications
• Lifecycle Efficiency: Modular design allows hot-swapping electronics without depressurization

• Multi-Variable Output: Simultaneous pressure, temperature, and calculated flow via HART® 7
• In-Situ Calibration: Remote zero/span adjustment via HART® communicator
• Self-Diagnostics: Real-time monitoring for clogged impulse lines, sensor faults, and EMI
• Temperature Compensation: Auto-correction for thermal effects on measurement stability
• Data Logging: Stores 100+ event records (min/max pressure, alarm history)
• Intrinsic Safety: IS barriers enable Zone 0 deployment without external isolators
