Recommended Calibration Tasks - Emerson Rosemount 3051P Reference Manual

Operation and maintenance
April 2020
WARNING
Replacement equipment or spare parts not approved by Emerson for use as spare parts
could reduce the pressure retaining capabilities of the transmitter and may render the
instrument dangerous.
Use only bolts supplied or sold by Emerson as spare parts. Improper assembly of manifolds
to traditional flange can damage sensor module.
WARNING
Improper assembly of manifolds to traditional flange can damage the device.
For safe assembly of manifold to traditional flange, bolts must break back plane of flange
web (i.e., bolt hole) but must not contact sensor module housing.
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users' equipment. This could be intentional or unintentional and
needs to be protected against.
Physical security is an important part of any security program and fundamental to
protecting your system. Restrict physical access by unauthorized personnel to protect end
users' assets. This is true for all systems used within the facility.

Recommended calibration tasks

CAUTION
Emerson calibrates absolute pressure transmitters at the factory.
Trimming adjusts the position of the factory calibration curve. If you trim the transmitter
improperly or with inaccurate equipment, you may degrade the transmitter's
performance.
