The Foxboro RH924WA is a high-accuracy industrial pressure transmitter designed for critical process measurement in demanding industrial environments. Part of Foxboro’s renowned RH Series, this transmitter features a robust stainless-steel housing with IP67 protection, ensuring reliability in harsh conditions like chemical processing, oil and gas, and power generation. Utilizing advanced piezoresistive sensor technology, it delivers precise gauge, absolute, or differential pressure measurements across a wide operating range. The RH924WA supports industry-standard 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, reducing lifecycle costs.
The RH924WA excels in mission-critical industrial processes:
