RH924YA Foxboro Distributed Control System Explosion Proof Industrial Pressure Transmitter

The Foxboro RH924YA is a high-precision industrial pressure transmitter designed for critical process measurement in harsh industrial environments. Part of Foxboro's renowned RH Series, this transmitter features a robust 316L stainless steel housing with IP68/IP69K protection, ensuring reliability in extreme conditions such as high humidity, corrosive chemicals, and high-pressure washdowns. Utilizing advanced piezoresistive sensor technology, it delivers highly accurate gauge, absolute, or differential pressure measurements across a wide operational range. The RH924YA supports 4-20 mA analog output with HART® 7 protocol compatibility, enabling seamless integration into distributed control systems (DCS) and SCADA networks. Its modular design simplifies maintenance and calibration, making it ideal for oil and gas, chemical processing, and power generation industries.

• Measurement Range: 0-10 kPa to 0-100 MPa (field-adjustable spans)
• Accuracy: ±0.05% of span (including linearity, hysteresis, and repeatability)
• Output: 4-20 mA analog with HART® 7 digital communication
• Process Connection: ½" NPT, G½", or DIN 16288 flanges
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Pressure Rating: 400 bar (5800 psi) burst pressure
• Wetted Materials: 316L stainless steel, Hastelloy® C-276 optional
• Certifications: SIL 2/3 (IEC 61508), ATEX/IECEx Zone 0/1, CE, RoHS
• Long-Term Stability: <±0.1% of URL per year

The RH924YA is engineered for mission-critical industrial processes:

• Oil & Gas: Wellhead pressure monitoring, pipeline integrity management, and separator vessel control
• Chemical Processing: Reactor pressure safety, distillation column optimization, and aggressive fluid handling
• Power Generation: Steam turbine pressure monitoring, boiler feedwater systems, and condenser vacuum measurement
• Pharmaceutical: Sterilization autoclave validation and CIP/SIP (Clean-in-Place/Sterilize-in-Place) processes
• Water Treatment: Pump protection, filter differential pressure monitoring, and reservoir level calculations

Its explosion-proof design (ATEX/IECEx) and SIL compliance make it indispensable for safety-instrumented systems (SIS).

1. Superior Accuracy: ±0.05% precision minimizes process variability and enhances product quality
2. Extreme Durability: 316L/Hastelloy® construction resists pitting, corrosion, and chemical erosion
3. Smart Diagnostics: HART® 7 enables predictive maintenance via real-time device health monitoring (e.g., sensor drift, overpressure alerts)
4. Safety Compliance: SIL 2/3 certification for functional safety-critical applications
5. Global Compatibility: Seamless integration with legacy Foxboro I/A Series systems and modern DCS platforms

• Multi-Variable Output: Simultaneously transmits pressure, temperature, and calculated flow rate via HART® 7
• In-Situ Calibration: Remote zero/span adjustment without interrupting the process
• Diagnostic Suite: Self-monitoring for clogged impulse lines, sensor faults, and electrical anomalies
• Temperature Compensation: Auto-correction for thermal effects on measurement stability
• Data Logging: Stores 200+ event records (e.g., min/max pressure, alarm history) for compliance audits
• Redundant Power Options: Supports dual power supplies for fail-safe operation
