Reach New Heights with Your Instrumentation

Rosemount 3051S Electronic Remote Sensors

A New Answer to an Old ProblemEveryone has an installation that

consumes time and resources,

whether it’s a distillation column

or an outdoor vessel with wide

varying temperatures. Impulse

lines can be unreliable, and long

lengths of capillary are hard

to work with. The Rosemount

3051S ERS™ System eliminates

mechanical worries and delivers

digital results.

Improve Performance

Measurement drift, caused by changes in ambient temperature,

is magnified by long lengths of impulse piping or capillary. The

3051S ERS System replaces mechanical components with a digital

architecture, resulting in a stable and repeatable measurement.

Simplify Maintenance and Reduce Costs

Cold-weather installations often require heat tracing. Impulse

lines need to be checked for leaks, condensation, evaporation,

and plugging. The 3051S ERS System eliminates these practices,

leaving you with more time to run your plant rather than fixing it.

Gain Greater Process Insight

Differential Pressure is a critical measurement for operating a

vessel or tower, but it doesn’t tell you everything. The 3051S ERS

System is a MultiVariable™ solution that gives you the information

you need to properly monitor and control your processes.

Go With What You Know

Using the latest technology does not have to be complicated and

require hours of training. The 3051S ERS System is simply a digital

upgrade to a proven and well understood technology: DP Level.

A Digital Upgrade to a Proven TechnologyThe Rosemount 3051S ERS

System is a new digital DP

Level architecture that replaces

impulse piping and capillary

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.

•Improve time response

by over 90%

•Eliminate temperature effects

and measurement drift

• Loop wiring and LCD can go

at top or bottom connection

• Process connections include

flanges, manifolds, and

remote seals

the applications you have

never been able to solve.

Emerson has the tools

and expertise to help you

implement the 3051S

ERS System and other

technologies successfully.

Taking a Proven Technology to New Heights

The 3051S ERS System

and Rosemount Tuned-

System™ Assemblies

are complimentary

technologies, allowing

you to use DP Level

instrumentation in more

places than ever before. Maximize your success

by using the 3051S ERS

System on distillation

towers, tall vessels, and

other applications with

long spans or wide-

varying temperatures.

Tuned-System Assemblies

will continue to be ideal

for installations with

shorter spans and

higher pressures.
