1 About this guide
This guide provides basic guidelines for Rosemount 3051
Transmitters.
It does not provide instructions for configuration, diagnostics,
maintenance, service, troubleshooting, explosion-proof, flameproof,
or Intrinsically Safe (IS) installations. Refer to the Rosemount 3051
Pressure Transmitter Manual for more instructions. This guide and
the referenced manual are also available on Emerson.com.
1.1 Safety messages
WARNING
Explosions
Explosions could result in death or serious injury.
Before connecting a communication device in an explosive
atmosphere, ensure that the instruments are installed in
accordance with intrinsically safe or non-incendive field wiring
practices.
In an explosion-proof/flame-proof installation, do not remove the
transmitter covers when power is applied to the transmitter.
WARNING
Process leaks
Process leaks may cause harm or result in death.
To avoid process leaks, only use the O-ring designed to seal with
the corresponding flange adapter.
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
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 in protecting your system. Restrict physical access by
unauthorized personnel to protect end users’ assets. This is true for
all systems used within the facility.
NOTICE
Conduit/cable entries
Unless otherwise marked, the conduit/cable entries in the housing
enclosure use a ½–14 NPT form. Only use plugs, adapters, glands, or
conduit with a compatible thread form when closing these entries.
Entries marked M20 are M20 × 1.5 thread form. On devices with
multiple conduit entries, all entries will have the same thread form.
When installing in a hazardous location, use only appropriately listed
or Ex certified plugs, glands, or adapters in cable/conduit entries.

2 Mounting the transmitter
WARNING
Process connection temperatures above +185 °F (+85 °C) require a
limited ambient temperature, reduced by a 1:1.5 ratio.
Consider process connection and ambient temperatures when
installing the 3051 with hazardous location certifications. See Table
2-1.
Table 2-1: Intrinsically safe/increased safety
Process connection temperature Maximum ambient temperature
-76 to +185 °F (-60 to +85 °C) +158 °F (+70 °C)
+185 to +250 °F (+85 to +121 °C) +158 to +320 °F (+70 to +160 °C)(1)
(1) Maximum ambient temperature is reduced by a ratio of 1:1.5 as process
connection temperature increased beyond +185 °F (+85 °C).
2.1 Mount the transmitter in a liquid flow application
Procedure
1. Place taps to the side of the line.
2. Mount the transmitter beside or below the taps.

3. Mount the transmitter so that the drain/vent valves are
oriented upward.
2.2 Mount the transmitter in a gas flow application
NOTICE
A bracket is required to support the transmitter and the ¼-inch
tubing going into the transmitter.
Procedure
1. Place taps in the top or side of the line.

2. Mount the transmitter beside or above the taps.
2.3 Steam flow applications
Procedure
1. Place taps to the side of the line.
2. Mount beside or below the taps.
3. Fill impulse lines with water.

2.5 Bolting considerations
If the transmitter installation requires assembly of the process
flanges, manifolds, or flange adapters, follow these assembly
guidelines to ensure a tight seal for optimal performance
characteristics of the transmitters.
Use only bolts supplied with the transmitter or sold by Emerson as
spare parts. Figure 2-2 illustrates common transmitter assemblies
with the bolt length required for proper transmitter assembly.

Bolts are typically carbon steel or stainless steel. Confirm the material
by viewing the markings on the head of the bolt and referencing
Table 2-2. If bolt material is not shown in Table 2-2, contact your local
Emerson representative for more information.
2.5.1 Install bolts
NOTICE
Carbon steel bolts do not require lubrication and the stainless steel
bolts are coated with a lubricant to ease installation. Do not apply any
additional lubricant when installing either type of bolt.

Procedure
1. Finger-tighten the bolts.
2. Torque the bolts to the initial torque value using a crossing
pattern (see Table 2-2 for torque values).
3. Torque the bolts to the final torque value using the same
crossing pattern (see Table 2-2 for torque values).
4. Verify that the flange bolts are protruding through the isolator
plate before applying pressure.

2.6 O-rings with flange adapters
WARNING
Failure to install proper flange adapter O-rings may cause process
leaks, which can result in death or serious injury.
The two flange adapters are distinguished by unique O-ring grooves.
Only use the O-ring that is designed for its specific flange adapter, as
shown in Figure 2-3.
