The Rosemount® 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. 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, simplified installations and maintenance, and additional process insight and diagnostics. The Electronic Remote Sensor system is built on the scalable 3051S architecture and is part of a broader portfolio of Rosemount DP level and process level technologies that include Tuned-System™ Assemblies, radar, ultrasonic, and switches.
