Emerson 2051CD1A02A1AS5 Smart Pressure Transmitter

Emerson's Rosemount 2051CD1A02A1AS5 Coplanar Differential Pressure Transmitter is part of the Rosemount 2051 family, engineered to sense differential pressure with a dedicated sensor module and electronics housing that provide robust isolation. The 2051CD variant uses capacitance sensor technology and is designed for direct compatibility with Rosemount Coplanar interfaces, enabling straightforward installation with manifolds, diaphragm seals, or primary flow elements as configured. It supports differential pressure ranges up to 2000 psi (137.9 bar) and outputs a 4-20 mA HART signal, with an optional 1-5 Vdc low-power protocol available on configured variants. A Local Operator Interface with built-in configuration buttons facilitates easy commissioning, and the unit can be delivered fully assembled for quick integration into DP systems. The Rosemount 2051 Coplanar family emphasizes safety and reliability, with SIL 2/3 certification to IEC 61508 via third-party assessment, making it suitable for safety-conscious process installations.
