Emerson Electric Co. 3144P Temperature Transmitter

Emerson's Rosemount 3144P Temperature Transmitter is a rugged two‑wire process transmitter that converts sensor temperatures into standardized signals for control systems, supporting either a 4–20 mA loop with HART communication or a fully digital FOUNDATION Fieldbus output for modern plant networks. The transmitter uses Rosemount X‑well technology and is housed in an IP66‑rated enclosure, designed to endure harsh industrial environments while delivering fast, stable temperature measurements. Its analog/digital measurement circuitry automatically self‑calibrates to maintain accuracy on every temperature update, and it is intended to work with Rosemount sensors and assemblies, accommodating common sensor types such as RTDs and thermocouples through compatible connection heads. The operating environment specifies an ambient temperature range typically from –40°C to +70°C, with installation guidance published by Emerson to ensure reliable performance in demanding applications. Widely used across process industries such as chemical processing, oil and gas, refining, and power generation, the 3144P is valued for high accuracy, stability, and long‑term reliability in temperature monitoring.
