NOTICE
This installation guide provides basic guidelines for Rosemount 3051 Transmitters. It does not provide
instructions for configuration, diagnostics, maintenance, service, troubleshooting, Explosion-Proof,
Flame-Proof, or intrinsically safe (I.S.) installations. Refer to the Rosemount 3051 Reference Manual for
more instruction. This manual is also available electronically on EmersonProcess.com/Rosemount.
WARNING
Explosions could result in death or serious injury.
Installation of this transmitter in an explosive environment must be in accordance with the appropriate
local, national, and international standards, codes, and practices. Review the approvals section of the
Rosemount 3051 Reference Manual for any restrictions associated with a safe installation.
Do not remove the transmitter cover in explosive atmospheres when the circuit is live.
Process leaks could result in death or serious injury.
To avoid process leaks, only use the O-ring designed to seal with the corresponding flange adapter.
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause
electrical shock.
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.

1.5 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 1-10 illustrates common transmitter assemblies with the bolt length
required for proper transmitter assembly.

Bolts are typically carbon steel (CS) or stainless steel (SST). Confirm the
material by viewing the markings on the head of the bolt and referencing
Table 1-1. If bolt material is not shown in Table 1-1, contact a local Emerson
representative for more information.
Procedure
1. Carbon steel bolts do not require lubrication and the stainless steel
bolts are coated with a lubricant to ease installation. However, no
additional lubricant should be applied when installing either type of
bolt.
2. Finger-tighten the bolts.
3. Torque the bolts to the initial torque value using a crossing pattern.
See Table 1-1 for initial torque value.

4. Torque the bolts to the final torque value using the same crossing
pattern. See Table 1-1 for final torque value.
5. Verify the flange bolts are protruding through the isolator plate before
applying pressure.

1.6 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 below.

B. O-ring
C. PFTE-based profile (square)
D. Elastomer profile (round)
Whenever the flanges or adapters are removed, visually inspect the O-rings.
Replace them if there are any signs of damage, such as nicks or cuts. If you
replace the O-rings, re-torque the flange bolts and alignment screws after
installation to compensate for seating of the PTFE O-ring.
1.7 Environmental seal for housing
Thread sealing (PFTE) tape or paste on male threads of conduit is required to
provide a water/dust tight conduit seals and meets requirements of NEMA®
Type 4X, IP66, and IP68. Consult factory if other Ingress Protection ratings are
required.
For M20 threads, install conduit plugs to full thread engagement or until
mechanical resistance is met.
1.8 In-line gage transmitter orientation
The low side pressure port (atmospheric reference) on the in-line gage
transmitter is located in the neck of the transmitter, behind the housing. The
