Emerson Process Management has released the industry’s first digital DP Level architecture, the Rosemount 3051S Electronic Remote Sensor system. With over 10 patents, the 3051S ERS system is a breakthrough technology that 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.
Ideal 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. When used in these types of applications, the 3051S ERS system can deliver:
* Improved performance: the 3051S ERS system replaces mechanical components with a digital architecture, resulting in faster response time and a more stable and repeatable measurement even in applications with wide varying temperatures.
* Simplified installation and maintenance: 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, resulting in cleaner installations with less maintenance and upkeep.
* Additional process insight and diagnostics: the 3051S ERS system is a MultiVariable solution that provides additional process information for optimised 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.
