INSTALLATION
PROCEDURES
For dimensional drawing information refer to Appendix A: Reference Data.
Electronics Housing
Provide 0.75 inches (19 mm) of clearance for units without an LCD display.
Three inches of clearance is required for cover removal if a meter is installed.
Cover Installation
Always ensure a proper seal by installing the electronics housing cover so the
o-ring is engaged. Use Rosemount O-rings.
Mount the Transmitter
The Rosemount 4500 is designed to be mounted directly to a process pipe or
vessel using a standard sanitary fitting. The transmitter is available with either
a 1.5 or 2-inch Tri-Clamp
®
connection or a fractional line fitting.
When installing the transmitter to the sanitary fitting it is important to use the
proper sanitary clamp and gasket (user-supplied). Check the clamp and
gasket specifications before installing. Refer to Table 2-2 for a list of standard
sanitary clamps, their respective maximum pressure ranges, and the
recommended torque to be applied when mounting.
