Product Description

Emerson Rosemount CD3A Pressure Transmitter

The Emerson Rosemount CD3A Pressure Transmitter is a high-precision, industrial-grade solution designed for reliable measurement of gauge or absolute pressure in demanding environments. Engineered for critical applications in oil and gas, chemical processing, power generation, and HVAC systems, the CD3A combines advanced sensor technology with robust mechanical design to deliver unmatched accuracy, durability, and ease of integration. Its ATEX/IECEx-certified explosion-proof construction ensures safe operation in hazardous zones, while its multivariable capabilities support enhanced process control.

Core Technical Performance The Rosemount CD3A offers ±0.075% of span accuracy (standard) and ±0.04% optional accuracy with calibration, covering a wide measurement range from 0–10 kPa to 0–100 MPa (0–1.45 psi to 0–14,500 psi). It provides a 4–20 mA analog output paired with HART® 7 digital communication, enabling seamless integration with PLCs, DCS, and SCADA systems for real-time data acquisition and remote diagnostics. Powered by 10.5–42 V DC loop power, the transmitter operates reliably in extreme ambient temperatures from -40°C to +85°C (-40°F to +185°F), with response times under 100 milliseconds to ensure dynamic process control. Its piezoresistive or capacitive silicon-on-sapphire sensor ensures long-term stability, even in fluctuating conditions.

Innovative Design and Durability Constructed with 316L Stainless Steel, Hastelloy C-276, or Tantalum wetted materials, the CD3A withstands exposure to corrosive, abrasive, or high-temperature media. Available with flanged (ANSI/DIN/JIS), threaded (NPT/BSP), or hygienic clamp-style connections, it adapts to global installation standards (ASME B16.5/B16.47, ISO 7005). The IP66/IP67-rated aluminum or stainless steel enclosure protects against dust, moisture, and mechanical impacts, while its sensors endure vibration (2g RMS) and shock (50g), ensuring reliability in offshore platforms, refineries, and chemical plants.

Advanced Communication and Diagnostics Equipped with HART® 7, the CD3A enables bidirectional communication for remote configuration, sensor health monitoring, and predictive maintenance alerts. This protocol supports integration with modern control systems, reducing unplanned downtime.
