MECHANICAL
CONSIDERATIONS
This section contains information you should consider when preparing to
mount the transmitter. Read this section carefully before proceeding to the
mechanical installation procedure.
Mount the Rosemount 1153 Series B Transmitter to a rigid support (i.e. a
support with a fundamental mechanical resonant frequency of 40 Hz or
greater). A mounting bracket included with the transmitter facilitates panel
mounting. Figure 2-4 on page 2-8 shows the qualified mounting
configurations. The transmitter was seismic qualified with the bracket
mounted with four
5
/
16
-in. diameter bolts. Orientation with respect to gravity is
not critical to qualification. However, if the transmitter is mounted with the
flanges in a horizontal position, for maximum accuracy, zero the transmitter to
cancel the liquid head effect caused by the difference in height of the process
connections.
If the transmitter is mounted to a non-rigid panel, the user must ensure that
seismic input to the mounting bracket does not exceed qualification levels
given in Rosemount Report 108025.
Process Connections
Process tubing installation must prevent any added mechanical stress on the
transmitter under seismic disturbances. This may be done by using
stress-relief loops in the process tubing or by separately supporting the
process tubing close to the transmitter.
The process connections to the transmitter flanges were qualified with
3
/
8
-in.
tubing using Swagelok
®
compression fittings. For options using
1
/
4
–18 NPT
connections, the user assumes responsibility for qualifying the interface.
Transmitters with Flange Options A, D, H, J, L, or M are shipped with
Swagelok fittings for process connections. Included are front ferrule, rear
ferrule, and nut. Ensure that the fittings are placed on the tubing with the
orientation and relative position shown in Detail A, Figure 2-5 on page 2-9.
Process tubing used is
3
/
8
-inch outside diameter, and of suitable thickness for
the pressure involved.
