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, explosionproof,

flameproof, or intrinsically safe (I.S.) installations. Refer to the

Rosemount 2051 Pressure Transmitter Reference Manual for

more instructions. This guide is also available electronically at

Emerson.com.

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 explosionproof/flameproof installation, do not remove the

transmitter covers when power is applied to the transmitter.

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 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 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.

Note

Before installing the transmitter, confirm the correct device driver is

loaded on the host systems.

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/DeviceInstallKits, or FieldCommGroup.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.

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, do not

apply any additional lubricant when installing either type of bolt.

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.

3. Torque the bolts to the final torque value using the same

crossing pattern.

See Table 3-1 for final torque value.
