Rosemount 3144P Temperature Transmitter

Product Description

The Rosemount 3144P Temperature Transmitter delivers exceptional precision and reliability for critical industrial processes. It supports dual-sensor input, allowing continuous measurement even if one sensor fails. Moreover, advanced diagnostics such as Hot Backup™, sensor drift alerts, and thermocouple degradation detection ensure uninterrupted process monitoring. Its robust dual-compartment housing enables field installation in harsh environments while maintaining stable operation.

By leveraging Rosemount X‑well™ Technology, the 3144P can measure temperature without process penetration, reducing installation costs and minimizing maintenance requirements. This transmitter is certified for SIL 2/3 applications, making it ideal for safety-critical systems in oil & gas, chemical, power generation, and food processing industries. In addition, flexible communication options, including HART® and FOUNDATION™ Fieldbus, simplify integration into modern automation systems.
