2.7 Differences between electronic remote sensors
and capillary systems
Rosemount 3051S Electronic Remote Sensors (ERS
™
) System technology utilizes two
Rosemount 3051S Pressure Transmitters connected via an electrical wire instead of a
single pressure transmitter with remote seals and capillary tubing. As the Rosemount
3051S ERS System calculates the differential pressure between the two transmitters,
capillary tubing is not needed, and thus eliminates all head temperature affects on the
system. Seals are not required, but may still be necessary on certain applications that
include high temperature, corrosive, or viscous processes. For more information, refer to
the Rosemount 3051S Series
Product Data Sheet .

2.8 Instrument Toolkit: seal ordering and
application process
Rosemount Instrument Toolkit Software is an instrumentation specification tool that can
be used to assist in product selection. This program analyzes application and process
conditions against a configured Rosemount model number and calculates the total system
performance including expected head and seal temperature effects and system response
times.
