Emerson 2051TG3A2B21AS5 Transmitter Assembly

Emerson's Rosemount 2051TG3A2B21AS5 Transmitter Assembly is an inline pressure transmitter bundled with a Rosemount 306 integral manifold (S5 option) for a compact, install-ready measurement system in piping or panel installations. As part of the Rosemount 2051 family, it provides differential, gauge and absolute pressure measurements and is designed for process environments where precise pressure monitoring matters. The S5 designation confirms that the transmitter ships with the Rosemount 306 integral manifold, and this specific configuration is often bundled with manifold code 0306RT22BA11, streamlining installation and reducing on-site assembly steps. The 2051 platform supports pressure ranges up to 800 psi for compatible configurations, enabling reliable monitoring in medium-pressure service common to oil and gas, refining and chemical processing facilities. In addition to its measurement capabilities, the Rosemount 2051 family emphasizes safety and reliability, with SIL 2/3 certification to IEC 61508 via third-party assessment and availability of prior-use FMEDA data for safety installations. This combination of robust mounting options and validated performance makes the 2051TG3A2B21AS5 a practical choice when a ready-to-install transmitter-manifold assembly is required for inline process connections.
