Rosemount 3051S Electronic Remote Sensor (ERS) System

The Rosemount 3051S ERS System is a digital DP Level architecture that links two Rosemount 3051S Pressure Sensors together electronically. The pressure sensors are synchronized on a single power loop where the differential pressure, level, and volume are calculated and transmitted using a standard two-wire 4–20mA HART® signal.

A digital upgrade to a proven technology
 90 percent improvement in time response
 Elimination of temperature effects and measurement drift
 Multivariable capabilities including DP, PLO, PHI, volume, and level
 Proven Rosemount 3051S Sensor technology
Simplified installations and maintenance routines
 Elimination of wet legs or dry legs
 Easy installations without need for heat tracing and insulation
 Proactive maintenance and troubleshooting with sensor alerts and diagnostics
 Simplified inventories with sensors and standard cable

Rosemount 1199 Seal Systems

A seal system consists of a pressure transmitter, one or two seals, a fill fluid, and either a direct mount or capillary style connection.
Seal systems provide a reliable process pressure measurement and prevent the process medium from contacting the transmitter diaphragm. Transmitter/diaphragm seal systems should be considered when:
 The process temperature is outside of the operating ranges of the transmitter.
 The process is corrosive and/or requires specific exotic materials of construction.
 The process contains suspended solids or is viscous and is prone to plugging of connections.
 The application requires the use of flush-mount hygienic connections that facilitates CIP/SIP service.
 There is a requirement for easier cleaning of the process from the connections to avoid contamination between batches.

Application flexibility
 Flanged, threaded, and hygienic process connections
 Meets industry standards such as EN 1092-1, ANSI/ASME B16.5, JIS B2238, ANSI/ASME B1.20.1, EN 10226-1, GOST 12815-80, ISO 228-1
 Variety of fill fluids applications including cold temperature, hot temperature, and hygienic and food grade
 Three different capillary diameters allow for optimization of accuracy and time response.

Reliable system construction
 Welded design with no threaded connections
 100% helium leak tested
 Advanced manufacturing techniques ensure air-free, leak-tight system that is stable over time
 Reliable operation in full vacuum applications

Robust seal design
 Backup convolutions on the diaphragm protect seal integrity.
 Recessed diaphragms reduce potential for handling damage.
