RH924YL Foxboro Distributed Control System Industrial Process High Reliability IP68

The Foxboro RH924YL is a high-accuracy differential pressure transmitter engineered for critical process measurement in extreme industrial environments. As part of Foxboro's flagship RH Series, this transmitter features a rugged Hastelloy C-276 sensor with full-welded construction, ensuring unmatched corrosion resistance in aggressive media like sulfuric acid, chlorine, or seawater. Designed for SIL 3 safety compliance, it delivers precise ΔP measurement (spanning 0.1 kPa to 40 MPa) with 4-20 mA + HART® 7 output. The RH924YL's IP68/NEMA 6P-rated stainless steel housing withstands submersible depths up to 20 meters, while its modular electronics enable field reconfiguration without process interruption. Ideal for refineries, chemical plants, and offshore platforms, it integrates seamlessly with Foxboro I/A Series DCS and modern control architectures.

• Measurement Range: 0.1 kPa to 40 MPa (customizable spans)
• Accuracy: ±0.04% of calibrated span (best-in-class)
• Wetted Materials: Hastelloy C-276 diaphragm, 316L SS process fittings
• Output: 4-20 mA analog + HART® 7 digital protocol
• Process Connections: ¼" to 2" ANSI/ASME flanges or threaded options
• Operating Temperature: -50°C to +130°C (-58°F to +266°F)
• Overpressure Limit: 400% of full scale
• Safety Certifications: SIL 3 (IEC 61508), ATEX/IECEx Zone 0/1
• Long-Term Drift: <±0.1% URL/10 years
• Certifications: CE, CRN, PED 2014/68/EU

The RH924YL excels in high-risk process industries:

• Oil & Gas: Offshore platform choke valve monitoring, separator interface detection, and subsea pipeline leak testing
• Chemical Processing: Corrosive reactor ΔP safety shutdown, chlorine gas liquefaction control
• Power Generation: Nuclear reactor coolant flow, turbine condenser vacuum measurement
• Pharmaceutical: Sterile bioreactor pressure balancing and CIP/SIP validation
• Pulp & Paper: Digester vessel pressure profiling and black liquor recovery

Its explosion-proof design (ATEX Category 1G) and SIL 3 certification make it indispensable for safety-instrumented systems (SIS).

1. Extreme Chemical Resistance: Hastelloy C-276 sensor survives pH 0-14 media and halogen exposure
2. Unrivaled Accuracy: ±0.04% precision reduces product loss in custody transfer applications
3. Zero Downtime Upgrades: Hot-swappable electronics and in-situ range adjustment via HART®
4. Lifecycle Integrity: 20-year design life with drift compensation algorithms
5. Global Compliance: PED, CRN, and SIL 3 certifications streamline multinational deployments

• Multi-Parameter Output: Simultaneous ΔP, static pressure, and temperature via HART® 7
• Predictive Diagnostics: Real-time monitoring of diaphragm integrity, plugging risk, and thermal stress
• Intrinsic Safety: IS barriers enable Zone 0 deployment without external isolators
• Data Historian: Stores 500+ event logs (overpressure events, calibration history)
• Auto-Zero Stabilization: Compensates for static line pressure effects
• FOUNDATION™ Fieldbus Option: Direct integration with Foxboro DCS architectures
