Quick Start Guide
1.5 Bolting considerations
If the transmitter installation requires assembly of a process flange, manifold, or
flange adapters, follow these assembly guidelines to ensure a tight seal for
optimal performance characteristics of the transmitter. Only use bolts supplied
with the transmitter or sold by Emerson
™
Process Management as spare parts.
Figure 1 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 1. If bolt material is
not shown in Table 1, contact a local Emerson Process Management
representative for more information.
