1 About this guide
This guide provides basic guidelines for Rosemount 2051 Pressure
Transmitters. It does not provide instructions for configuration, diagnostics,
maintenance, service, troubleshooting, Explosion-proof, Flameproof, or
intrinsically safe (I.S.) installations. Refer to Rosemount 2051 Reference
Manual for more instructions. This guide is also available electronically at
Emerson.com/Rosemount.
1.1 Safety messages
WARNING
Explosions could result in death or serious injury.
Installation of these transmitters 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 2051
Reference Manual for any restrictions associated with a safe installation.
In an explosion-proof/flameproof installation, do not remove the transmitter
covers when power is applied to the unit.
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 marked, the conduit/cable entries in the transmitter housing use a
½–14 NPT thread form. Entries marked “M20” are M20 × 1.5 thread form.
On devices with multiple conduit entries, all entries will have the same
thread form. Only use plugs, adapters, glands, or conduit with a compatible
thread form when closing these entries.

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.

2 System readiness
2.1 Confirm correct device driver
•Verify the correct device driver (DD/DTM™) is loaded on your systems to
ensure proper communications.
•Download the correct device driver at your host vendor download site,
Emerson.com or Fieldbus.org.
2.1.1 Device revisions and drivers
Table 2-1 provides the information necessary to ensure you have the correct
device driver and documentation for your device.

3.4 Bolting considerations
If the transmitter installation requires assembly of the process flanges,
manifolds, or flange adapters, follow the 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 3-2 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 3-1. If bolt material is not shown in Table 3-1, contact a local Emerson
representative for more information.
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.
Use the following bolt installation procedure:
Procedure
1. Tighten the bolts by hand.
2. Torque the bolts to the initial torque value using a crossing pattern.
See Table 3-1 for initial torque value.
