Bolting considerations

If the transmitter installation requires assembly of the process flanges, manifolds,

or flange adaptors, 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 illustrates

common transmitter assemblies with the bolt length required for proper

transmitter assembly.

Figure 1. Common Transmitter Assemblies

A. Transmitter with coplanar flange

B. Transmitter with coplanar flange and optional flange adaptors

C. Transmitter with traditional flange and optional flange adaptors

D. Transmitter with coplanar flange and optional Rosemount Conventional Manifold and flange

adapters

Bolts are typically carbon steel or stainless steel. Confirm the material by viewing

the markings on the head of the bolt and referencing Figure 3. If bolt material is

not shown in Figure 3, contact the local Emerson Process Management

representative for more information.

Use the following bolt installation 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.
