Electronic Remote Sensor System Includes DP-Level Technology
Emerson Process Management has released its DP-level architecture, the Rosemount 3051S Electronic Remote Sensor system. With more than 10 patents, the 3051S ERS System replaces mechanical impulse piping with two 3051S pressure sensors linked together electronically. Differential pressure is calculated in one of the two sensors and is transmitted using a standard two-wire 4-20 mA HART signal.
Suitable applications for the 3051S ERS system include tall vessels, distillation towers, and other installations that traditionally have required excessive lengths of impulse piping or capillary. The 3051S ERS replaces mechanical components with a digital architecture, potentially resulting in faster response time and a more stable and repeatable measurement, including applications with wide varying temperatures.
Cold-weather installations often require heat tracing or insulation. Impulse lines need to be checked for leaks, condensation, evaporation, and plugging. The digital architecture of the 3051S ERS System eliminates these practices.
The 3051S ERS System is a MultiVariable solution that provides additional process information for optimized control. In addition to the DP calculation, the 3051S ERS provides real-time access to the readings from each pressure sensor and a scaled output for tank level or volume measurement.
