WARNING
Electrical shock
Electrical shock can result in death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads
can cause electrical shock.
WARNING
Spare parts
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.
CAUTION
Improper assembly
Improper assembly of manifolds to traditional flange can damage sensor module.
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.

Considerations

3.3.1 Installation considerations
Measurement accuracy depends upon proper installation of the transmitter and impulse
piping. Mount the transmitter close to the process and use a minimum of piping to
achieve best accuracy. Keep in mind the need for easy access, personnel safety, practical
field calibration, and a suitable transmitter environment. Install the transmitter to
minimize vibration, shock, and temperature fluctuation.
Important
Install the enclosed pipe plug (found in the box) in unused housing conduit opening with a
minimum of five threads of engagement to comply with explosion-proof requirements.
For material compatibility considerations, refer to Material Selection
3.3.2 Environmental considerations
The best practice is to mount the transmitter in an environment that has minimal ambient
temperature change.
The transmitter electronics operating temperature limits are -40 to 185 °F (-40 to 85 °C).
Refer to the Specifications section in the Rosemount
sensing element operating limits. Mount the transmitter so it is not susceptible to
